The Corsair Flash Padlock 2 secure USB drive offers external buttons to enter a key code, which unlocks the drive for use on virtually any type of computer. Because the drive doesn't require software to unlock, and because the data on it is protected with 256-bit encryption, reviewers had a lot of good things to say about its features. It is not FIPS 140-2 compliant, so government offices or other workplaces requiring that level of security will not be able to use the Flash Padlock 2. Some user reviews offer another caution, suggesting that, depending on the network configuration of the computer you use to read the drive, not having administrator access on the computer may keep you from accessing your files.
But with those caveats, reviewers found a great deal to like, including the drive's rugged casing and ease of use. While it is not completely waterproof, it did survive at least one reviewer's washing machine test. Transfer speeds were consistently low, barely average for a USB 2.0 drive, but a tradeoff most reviewers were willing to make for the extra security.
Most reviews date from the Flash Padlock 2's 2010 launch, when it was only available in an 8 GB size, but their tests still apply to the current model, which is also available as a 16 GB drive. Detailed reviews at a number of sites test the drive's transfer speeds and durability. TechReport.com runs it through a washing machine, TechPowerUp.com gives an extensive overview of the strengths and weaknesses of its data security, and ThinkComputers.org hosts a video detailing exactly how the drive works.

While dated, this review of the 8 GB version of the Corsair Flash Padlock 2 USB drive still pertains to the model currently for sale. LegitReviews.com praises the hardware-based security on the drive; the security code is entered with buttons on the drive, so it works equally well on PC, Mac and Linux platforms and is protected from keyloggers and software hacks. However, because it requires administrative rights on some host computers to use (depending on your network setup), it may not be suitable for all users, Joe Evans writes.

R. Scott Clark praises the Corsair Flash Padlock 2 Secure USB drive in this review, noting its strong security, "master PIN" for parents or system administrators, platform independence, and cooldown after unsuccessful code attempts. It is not FIPS 140-2 government security standard compliant, he notes, and offers only moderate transfer speeds. "Corsair's Flash Padlock 2 secure flash drive is hands-down your best option for transporting sensitive data that's not government classified," Clark writes.

The transfer speeds are average, but the drive makes it through the wash with flying colors, still functioning perfectly a month later. Tester Cyril Kowaliski praises the drive's security, ruggedness and 10-year warranty, but says transfer speeds and the price are still disappointing.
