Encrypted USB flash drives fall into two camps: affordable software-encrypted models and pricier hardware-encrypted drives that meet strict government standards. My top pick, the Apricorn Aegis Secure Key 3 NX 64GB, earns the best overall spot thanks to its onboard keypad, FIPS 140-2 Level 3 validation, and rugged, dust- and water-resistant housing. For buyers on tighter budgets, the Integral 32GB Secure 360 delivers PIN-protected encryption at a fraction of the price, while the Kingston IronKey Vault Privacy 50 suits everyday users who want solid protection without a physical keypad. The main tradeoffs to weigh are cost versus certification level, capacity versus security features, and whether you need keypad entry for devices without keyboards. Keep reading for the full breakdown of all eight drives.
Key Takeaways
- Hardware encryption with physical keypads (Apricorn Aegis Secure Key 3 NX, iStorage datAshur PRO, Kingston IronKey Keypad 200) offers markedly stronger protection than software-based models, but costs more per gigabyte and adds bulk.
- Integral dominates the value end: its Secure 360 and Crypto-197 lines cover capacities from 4GB to 64GB, making them the go-to choice for budget buyers who still want real encryption rather than none at all.
- Capacity does not equal security: the 4GB Integral Crypto-197 offers the same 256-bit encryption as its larger siblings, so buyers paying for big storage should confirm they are not paying twice for the same protection tier.
- Keypad drives are the only practical choice for use with TVs, projectors, printers, and other host devices without a keyboard, which single-handedly justifies their premium for many business users.
- Only the Apricorn Aegis Secure Key 3 NX and iStorage datAshur PRO carry FIPS 140-2 Level 3 validation in this lineup, a hard requirement for healthcare, government, and defence-related work.

More Details on Our Top Picks
Integral 32GB Secure 360 Encrypted USB 3.0 Flash Drive
For most people who need to keep tax documents, work files, or personal backups safe without wading through security jargon, this is where I would point them first. The 256-bit AES encryption runs automatically once you set a password, and the zero-footprint design means nothing gets installed on the host computer — a genuine convenience compared with the PIN-entry routine the Kingston IronKey Keypad 200 demands every single time. USB 3.0 speeds and the rotating capless housing make it pleasant to live with day to day. The tradeoff is seriousness: unlike the IronKey or the iStorage datAshur PRO, it carries no FIPS certification, so regulated workplaces may not accept it. The auto-erase after failed attempts is protective but unforgiving if you fat-finger your password too often.
Pros:- 256-bit AES encryption with no software installation needed
- Works on both Windows and macOS out of the box
- Automatic data erasure after repeated failed attempts stops brute-force guessing
- USB 3.0 speeds with a practical rotating capless design
Cons:- Only 32GB of storage, which fills up fast with media or backups
- Auto-erase can permanently destroy your data if you mistype the password repeatedly
- No certification backing, so it falls short of professional compliance requirements
Best for: Students and office workers who want set-and-forget encryption for everyday files on a modest budget
Not ideal for: Anyone handling regulated or classified data — there’s no FIPS validation, and compliance teams will reject it
- Capacity:32 GB
- Encryption:256-bit AES
- Interface:USB 3.0
- Software Required:No — zero footprint, no installation
- Security Feature:Intelligent password protection with automatic data erasure
- Compatibility:Windows, macOS
- Warranty:2 years
Our verdict“This is the pick for ordinary people who want strong encryption without complexity — as long as their data isn’t compliance-sensitive.”
Integral 16GB Crypto-197 256-Bit Hardware Encrypted USB 3.0 Secure Flash Drive
What separates this model from its sibling, the Integral Secure 360, is that the encryption happens in hardware and carries FIPS 197 certification — meaning an independent body has validated the AES implementation. That matters if anyone audits how you protect files. The waterproof double-layer housing also makes it the more durable of the two Integral options, surviving conditions that would kill a standard plastic drive. Compared with the Apricorn Aegis Secure Key 3 NX, it lacks admin modes and read-only options, so it’s not an IT-deployment tool — but for a single user moving sensitive documents between machines, it covers the fundamentals honestly. The sting is capacity: 16GB is genuinely tight if you handle large files, and the forced high-strength password policy will annoy casual users.
Pros:- FIPS 197 certified AES 256-bit hardware encryption
- Waterproof, shock-resistant double-layer construction
- Auto-lock and brute-force attack protection without any software
- Cross-platform plug-and-play on PC and Mac
Cons:- 16GB capacity limits it to documents and smaller archives
- Mandated high-strength passwords make casual access tedious
- No admin or multi-user modes for managed deployments
Best for: Field workers and contractors who need certified hardware encryption that survives rain, drops, and rough bags
Not ideal for: Anyone transporting large files or media — 16GB disappears quickly, and there’s no bigger sibling in this exact line with the same rugged build
- Capacity:16 GB
- Encryption:AES 256-bit hardware encryption
- Certification:FIPS 197
- Interface:USB 3.0
- Waterproof:Yes
- Protection Features:Brute-force attack protection, auto-lock, rugged double-layer design
- Software Required:No
Our verdict“The smart choice when durability and certified encryption matter more than storage space.”
Kingston IronKey Keypad 200 16GB Encrypted USB
This is the drive for people whose threat model includes someone else’s computer. Because you enter the PIN on the onboard alphanumeric keypad, the password never touches the host machine — no keyloggers, no malware scraping your credentials. That’s a layer of protection neither the Integral Secure 360 nor the Integral Crypto-197 can offer, since both rely on host-typed passwords. The XTS-AES 256-bit encryption with multi-PIN support (admin plus user PINs) puts it in the same professional tier as the Apricorn Aegis Secure Key 3 NX, though its FIPS 140-3 Level 3 status is still pending, which buyers in strict regulatory environments should verify before committing. The keypad also means the drive is chunkier and heavier than software-based rivals, and 16GB won’t hold much beyond documents.
Pros:- On-device alphanumeric keypad defeats host-based keyloggers
- Multi-PIN support separates admin and user access
- XTS-AES 256-bit hardware encryption with BadUSB attack protection
- Brute-force protection physically locks the drive after failed attempts
Cons:- FIPS 140-3 Level 3 certification is pending, not finalized
- 16GB capacity is small for anything beyond documents
- Keypad adds noticeable size and per-use effort
Best for: Journalists, consultants, and executives who frequently plug into untrusted machines and need PIN entry that bypasses the host entirely
Not ideal for: Anyone wanting a pocketable everyday drive — the keypad hardware makes it bulky, and typing a PIN each use adds friction for casual file transfers
- Capacity:16 GB
- Encryption:XTS-AES 256-bit hardware encryption
- Certification:FIPS 140-3 Level 3 (pending)
- Access Method:Onboard alphanumeric keypad
- Security Features:Multi-PIN, brute-force protection, BadUSB protection
- Software Required:No
Our verdict“The most defensible option here for use on compromised or public computers, provided the pending certification isn’t a dealbreaker for your compliance team.”
Apricorn Aegis Secure Key 3 NX 64GB Encrypted USB 3.0 Flash Drive
Where most drives in this lineup serve one person, the Aegis Secure Key 3 NX is built for managed deployments. Separate admin and user modes let an IT department control access without sharing the master PIN, and the two read-only modes let you share files with confidence that nothing on the drive gets modified or infected. Add data recovery PINs and you have recovery paths the Kingston IronKey Keypad 200 matches in spirit but with less configurability. At 64GB, it also doubles the practical storage of every hardware-keypad rival here except the larger Integral options, which lack these admin features entirely. The honest caveats: its FIPS 140-2 Level 3 validation is listed as pending, and security features of this caliber push the price well above simple encrypted sticks — overkill for a lone user with a folder of tax PDFs.
Pros:- Separate admin and user modes for managed multi-user access
- Two read-only modes protect data integrity when sharing
- Recovery PINs provide a path back in if a user PIN is lost
- 64GB capacity comfortably handles larger encrypted archives
Cons:- FIPS 140-2 Level 3 validation is pending rather than confirmed
- Enterprise feature set commands a premium over simpler drives
- Heavier configuration burden than plug-and-go options like the Integral Secure 360
Best for: IT departments issuing encrypted drives to staff, where admin controls, read-only sharing, and recovery PINs are non-negotiable
Not ideal for: Individual users with modest security needs — you’d be paying for enterprise management features you’ll never configure
- Capacity:64 GB
- Encryption:256-bit hardware encryption
- Validation:FIPS 140-2 Level 3 (pending)
- Interface:USB 3.0
- Access Modes:Admin mode, user mode, two read-only modes
- Recovery:Data recovery PIN support
Our verdict“The right buy when one person manages the security and many people use the drive — solo buyers can safely skip it.”
iStorage datAshur PRO 4GB Encrypted USB Memory Stick
No other drive in this batch arrives with heavier paperwork: FIPS 140-2 Level 3 certification (finalized, not pending, unlike the Apricorn Aegis Secure Key 3 NX and the Kingston IronKey Keypad 200), plus NATO Restricted and NLNCSA DEP-V approvals. If your organization literally requires those acronyms on a procurement form, this is the only compliant answer here. The IP57 water and dust resistance and AES-XTS 256-bit hardware encryption with onboard PIN entry put it in the same durability and security tier as the IronKey, with markedly broader platform support — Linux, Android, Citrix, and thin clients included. The compromise is stark: at 4GB, you’re carrying documents, credentials, and small archives, nothing more. And like all PIN-entry drives, every use starts with typing a code, which grates if you access files dozens of times a day.
Pros:- Finalized FIPS 140-2 Level 3 certification plus NATO Restricted and NLNCSA approvals
- Onboard PIN authentication keeps credentials off the host machine
- IP57 water and dust resistance for harsh environments
- Extremely broad compatibility including Linux, Android, Citrix, and thin clients
Cons:- 4GB capacity is the smallest in this roundup by a wide margin
- PIN entry adds friction to every access session
- No biometric or convenience-focused alternative to PIN authentication
Best for: Government contractors and defense-sector staff whose data handling policies mandate FIPS 140-2 Level 3 or NATO Restricted certification
Not ideal for: Anyone storing more than a few gigabytes — media, backups, and large datasets simply won’t fit on 4GB
- Capacity:4 GB
- Encryption:AES-XTS 256-bit hardware encryption
- Certification:FIPS 140-2 Level 3, NLNCSA DEP-V, NATO Restricted
- Access Method:Onboard PIN authentication
- Durability:IP57 water and dust resistance
- Transfer Speeds:Up to 169MB/s read, 135MB/s write
- Compatibility:Windows, macOS, Linux, Chrome, Android, thin clients, Citrix, VMware
- Software Required:No
Our verdict“Buy it when the certification list is the requirement — skip it the moment you need actual storage space.”
Integral 4GB Crypto-197 256-Bit USB 3.0 Encrypted Flash Drive with Waterproof Double Layer Design
Most encrypted drives in this roundup promise to keep your files safe from hackers, but very few address the more common threat: physical damage. This model stands out for its waterproof double-layer housing, which makes it a better fit for fieldwork, job sites, and travel than the standard Integral Secure 360, which offers no environmental protection at all. Like the larger Integral 16GB Crypto-197, it carries FIPS 197 certification with 256-bit AES hardware encryption and brute force attack protection, so the security pedigree matches its pricier siblings. The tradeoff is stark, though: 4GB is genuinely small. Compared with the Kingston IronKey Vault Privacy 50, you give up capacity and multi-password flexibility in exchange for a lower cost of entry and a tougher shell. No software installation is needed, which keeps setup painless on both PC and Mac.
Pros:- FIPS 197 certified 256-bit AES hardware encryption with brute force protection
- Waterproof double-layer housing survives conditions most encrypted drives can’t
- No software installation needed — works immediately on PC and Mac
- Auto-lock feature protects data if the drive is left unattended
Cons:- 4GB capacity is far too small for modern file sets or backups
- Password-only access with no biometric or keypad option like the IronKey Keypad 200
- USB 3.0 speeds lag well behind drives like the Secure 360 lineup
Best for: Field technicians, students, and travelers who carry only small batches of sensitive documents and need a drive that shrugs off rain and rough handling
Not ideal for: Anyone moving large files, video footage, or encrypted backups — 4GB fills up after a handful of documents or presentations
- Capacity:4GB
- Encryption:256-bit AES hardware
- Certification:FIPS 197
- Connection:USB 3.0
- Protection Features:Waterproof, brute force attack protection, auto-lock
- Software Required:None
- Compatibility:PC and Mac
Our verdict“This pick makes the most sense for buyers who prioritize physical durability and certified encryption over storage space.”
Integral 64GB Secure 360 Encrypted USB 3.0 Flash Drive
When the job is moving big encrypted archives quickly, capacity and throughput matter more than rugged housings, and that’s exactly where this drive earns its spot. With 64GB of storage and read speeds quoted up to 625 MB/s, it outpaces every other Integral option here, including the Integral 32GB Secure 360, which halves your storage for similar security. The 256-bit AES encryption matches what you get on the Crypto-197 line, so you’re not trading protection for speed. The compromises are real, though: unlike the Crypto-197, there’s no waterproof shell, and unlike the Apricorn Aegis Secure Key 3 NX, there’s no physical keypad — you’re relying on software-based unlocking. Its 60 MB/s write speed is also noticeably slower than its read rate, so large outbound transfers take patience. For buyers whose bottleneck is storage size rather than attack resistance, this is the strongest Integral offering in the lineup.
Pros:- 64GB capacity is the largest in this roundup’s Integral range
- Very fast read speeds of up to 625 MB/s for quick file retrieval
- 256-bit AES encryption protects data at rest
- Compact and lightweight enough for pocket or keychain carry
Cons:- Write speed of 60 MB/s makes large save operations slow
- No waterproofing or shockproofing unlike the Crypto-197 line
- Lacks FIPS certification and physical keypad options found on Apricorn or iStorage rivals
Best for: Photographers, video editors, and IT staff who need to transport large encrypted archives between machines on a budget
Not ideal for: Government or high-security users who need FIPS certification, a physical keypad, or rugged environmental protection
- Capacity:64GB
- Encryption:256-bit AES
- Connection:USB 3.0
- Read Speed:Up to 625 MB/s
- Write Speed:60 MB/s
- Color:Black
- Compatibility:USB-equipped PCs and Macs
Our verdict“Choose this if you need the most encrypted storage per dollar and care more about transfer speed than military-grade physical security.”
Kingston IronKey Vault Privacy 50 16GB Encrypted USB
This model is better suited to regulated workplaces than any other drive in this batch, and the reasons are specific rather than cosmetic. TAA compliance means it can pass procurement rules that rule out the Integral drives entirely, and protection against BadUSB and brute force attacks addresses firmware-level threats that basic AES encryption alone doesn’t cover. Compared with the IronKey Keypad 200, the Vault Privacy 50 swaps the onboard keypad for multi-password (Admin and User) support plus a write-protect switch — arguably more practical for IT teams managing shared devices than punching codes on the drive itself. Its 180 MB/s write speed comfortably beats the Integral Secure 360‘s 60 MB/s, so encrypted backups finish faster. The catch: 16GB is modest next to the 64GB Secure 360, and at this price point the capacity-to-cost ratio favors consumer drives if compliance isn’t a requirement.
Pros:- TAA compliant for government and regulated procurement
- Multi-password Admin/User mode and write-protect switch for flexible access control
- Protection against BadUSB and brute force attacks at the firmware level
- 180 MB/s write speed is quick for an encrypted 16GB drive
Cons:- 16GB capacity limits use for large archives or full backups
- Higher cost per gigabyte than non-compliant consumer alternatives
- No rugged waterproof housing like the Integral Crypto-197
Best for: Government contractors, corporate IT departments, and compliance-driven organizations that need TAA-compliant, policy-manageable encrypted storage
Not ideal for: Budget buyers or anyone needing large capacity — cheaper Integral options deliver similar AES encryption with more storage
- Capacity:16GB
- Encryption:AES 256-bit hardware
- Connection:USB 3.2 Gen 1
- Read Speed:250 MB/s
- Write Speed:180 MB/s
- Security Features:Multi-password, write-protect, BadUSB and brute force protection
- Compliance:TAA compliant
- Color:Blue
Our verdict“If your organization demands verified compliance and firmware-level attack protection, this is the drive to buy; everyone else can save money elsewhere.”
How We Picked
I evaluated each drive against the factors that actually determine whether an encrypted USB stick does its job: encryption strength and certification (hardware versus software, 256-bit AES, FIPS validation), usability (keypad entry, admin PINs, auto-lock behavior, cross-platform compatibility), build quality (water, dust, and tamper resistance), and capacity relative to price. Drives that self-destruct their encryption keys after repeated wrong PIN attempts scored higher, because brute-force resistance matters more than raw transfer speeds for this category.
The ranking logic is straightforward: certified hardware-encrypted drives with keypads sit at the top because they protect data even on compromised machines; mid-tier hardware-encrypted models without keypads follow; and affordable software-encrypted Integral models fill out the value end for lower-risk everyday use. I also factored in warranty length, since a drive that fails takes your data with it, and whether each model works across Windows, macOS, Linux, and embedded hosts without extra software.

Factors to Consider When Choosing Encrypted USB Flash Drives
Choosing an encrypted flash drive involves more than picking a capacity. These are the factors that separate a drive that genuinely protects your files from one that only looks secure.Hardware vs. Software Encryption
This is the single biggest fork in the road. Software-encrypted drives rely on a program running on your computer to scramble files, which means they can be vulnerable to keyloggers, malware, and screen-capture attacks on a compromised machine. Hardware-encrypted drives handle encryption inside the drive itself with a dedicated chip, so the PIN is entered on the device (or via a pre-boot environment) and never touches the host operating system. If you handle client data, financial records, or anything covered by GDPR or HIPAA-style rules, hardware encryption is not a luxury, it is the baseline. Software encryption remains reasonable for personal files like tax documents or family photos, where the realistic threat is a lost bag rather than a targeted attack. A common mistake is assuming the word “encrypted” on the box means hardware encryption; always check the specification for an onboard encryption processor.
FIPS Certification and Compliance
If you work in healthcare, government, legal services, or for an enterprise with a security policy, check whether your organization mandates FIPS 140-2 or 140-3 validation. Only a handful of drives in this roundup carry it, and it is not a badge you can retrofit: the certification covers the specific cryptographic module inside the drive. Paying extra for a certified model when your employer does not require it is wasted money, but buying a non-certified drive when it is required can get data handling policies violated and contracts lost. The practical takeaway is to confirm requirements with your IT or compliance team before buying, not after. Also verify which level applies, since FIPS 140-2 Level 3 (tamper-evident and tamper-responsive designs) demands far more from the hardware than Level 2.
Keypad Entry and Host Compatibility
A physical keypad sounds like a gimmick until you try using a PIN-only drive with a smart TV, photocopier, car stereo, or industrial machine that has no keyboard input. Keypad drives like the Apricorn, iStorage, and IronKey Keypad 200 work with virtually any USB host because unlocking happens on the drive itself. The tradeoff is physical: keypads add thickness, moving parts that can wear, and a higher price. Software-based unlocking is fine if you only ever plug into your own laptop, but it quietly locks you out of embedded devices. Another often-missed point: keypad drives let you unlock on one machine and remain readable if you move them, whereas software drives may need their app installed on every computer you touch.
Brute-Force Protection and Self-Destruct
Serious encrypted drives do not just lock after wrong attempts, they cryptographically erase the encryption key, rendering the stored data permanently unreadable. This is the feature that stops someone from trying thousands of PIN combinations over months. Look for specifics: how many wrong attempts trigger the wipe (typically around 10), whether admin mode can rescue a locked drive, and whether the wipe can be disabled if you are worried about a toddler or a bad memory. Buyers with a history of forgotten passwords should think hard here, because self-destruct means there is no recovery path, no manufacturer backdoor, and no data-recovery service that can help. That finality is exactly what makes it good security and bad user experience at the same time.
Capacity, Speed, and Real-World Use
Encrypted drives lag behind plain flash drives on price per gigabyte, sometimes by a wide margin, so overbuying capacity is an expensive habit. Ask what actually needs encrypting: most people carrying contracts, scans, and password vaults need well under 16GB, while backups of client projects justify 64GB or more. USB 3.0 is the practical floor in 2026; USB 2.0 models make encrypted file transfers painfully slow because the encryption process adds overhead on top of the bus speed. Also note that hardware-encrypted drives often read and write slower than their plain counterparts even on USB 3.0, since every byte passes through the encryption engine. Waterproof and dustproof ratings (IP57 and similar) matter more for field workers than office users, but they cost little extra on some models and add genuine peace of mind.
Admin Mode, Multiple PINs, and Deployment
Beyond the basic user PIN, better drives offer an admin mode that lets an administrator reset a forgotten user PIN without wiping the drive, configure read-only modes, or set policy-enforced PIN lengths. This distinction matters most for teams: a single-user drive handed between staff becomes a liability the first time someone forgets their code. If you manage several drives, look for one-time recovery codes and the ability to program multiple drives from a central utility, features the Apricorn and iStorage models in this roundup support. Solo users can safely ignore these features and save money. The mistake I see most often is small businesses buying consumer-grade drives for staff use, then discovering there is no way to recover a locked drive without destroying the data.
Frequently Asked Questions
Do I really need a FIPS-certified encrypted drive, or is 256-bit AES enough?
The encryption algorithm itself is rarely the weak point; both certified and uncertified drives typically use 256-bit AES, which is computationally unbreakable with current technology. FIPS validation is about the implementation: it certifies that the key generation, storage, and tamper protections meet audited standards, closing loopholes like keys held in readable memory or predictable random number generation. You need FIPS if your employer, a client contract, or a regulation like HIPAA explicitly requires it. For personal files, a well-designed non-certified hardware-encrypted drive still offers far better protection than no encryption or software-only solutions. Paying double for certification you are not required to have makes little sense, but assuming all 256-bit drives are equivalent is an even bigger mistake.
What happens if I forget my PIN on a hardware-encrypted drive?
On most serious encrypted drives, forgetting the user PIN is survivable only if an admin PIN was set up beforehand; the admin can issue a new user PIN without data loss. If no admin PIN exists, or you forget both, the data is gone for good, because these drives have no manufacturer backdoor or recovery service. After the configured number of wrong attempts (commonly ten), the drive cryptographically erases its own encryption key, and no laboratory can decrypt the storage afterward. My advice is to always configure the admin PIN during setup and store it somewhere separate from the drive, like a password manager. This is the single most common way people lose their own encrypted data, and it is entirely preventable.
Can I use a keypad-encrypted USB drive with a TV, printer, or car stereo?
Yes, and that is precisely the scenario where keypad drives justify their higher price. Because you enter the PIN on the drive’s own buttons rather than through the host device, the drive unlocks before the host ever sees it, so it behaves like a normal USB stick to whatever it is plugged into. Software-encrypted drives generally cannot do this, since they need an app or at least a keyboard to accept your password. The Kingston IronKey Keypad 200, Apricorn Aegis Secure Key 3 NX, and iStorage datAshur PRO all work this way. One caveat: some embedded devices have strict file system support, so confirm the drive presents a standard format the host can read once unlocked.
Is a cheap encrypted drive like the Integral Secure 360 actually secure?
For its price bracket, yes, provided you understand what you are getting. The Secure 360 line offers PIN-based protection and encryption that is leagues ahead of carrying unencrypted files, and it is a sensible choice for students, home users, and low-sensitivity work documents. Where it falls short of premium drives is in certification, tamper resistance, and resilience against a determined attacker with physical access to the device or a compromised computer. If your threat model is a lost or stolen bag, it is entirely adequate. If your threat model includes targeted attacks or regulatory obligations, spend more on a FIPS-validated hardware-encrypted model.
How much capacity do I need on an encrypted flash drive?
Most buyers overestimate this. Encrypted drives are for sensitive files, not bulk storage, and the typical payload of documents, scans, and small archives fits comfortably in 16GB. Choose 64GB only if you regularly move encrypted backups, large client projects, or media files, and remember that encrypted drives command a premium per gigabyte compared with ordinary flash storage. Also consider that smaller certified drives like a 4GB Crypto-197 deliver identical protection to larger models, so if your files are small, the low-capacity version is the smarter buy. Speed is the other side of the coin: larger transfers on USB 3.0 encrypted drives still take noticeably longer than on plain drives due to encryption overhead.
Conclusion
The right pick depends entirely on what you are protecting and where you plug in. For most buyers who need serious security, the Apricorn Aegis Secure Key 3 NX 64GB is the best overall choice: FIPS 140-2 Level 3 validation, keypad unlocking that works with any USB host, and a rugged housing make it the most complete package here. The iStorage datAshur PRO is the best premium alternative when you want similar certified protection in a different form factor or need its specific admin and deployment features.
Value seekers should look at the Integral 32GB Secure 360, which brings genuine PIN protection to a budget-friendly price point, with the 64GB version for those needing more room. Beginners and casual users are well served by the Kingston IronKey Vault Privacy 50, which balances strong hardware encryption with simple everyday usability. For specific needs, the Kingston IronKey Keypad 200 handles locked-down corporate environments, the 16GB Integral Crypto-197 suits small document sets on a strict budget, and the waterproof 4GB Crypto-197 is a rugged, pocketable option for field work where capacity matters less than survivability. Match the drive to your real threat level rather than buying the most expensive option by default, and you will land on the right one.
