A 32 GB encrypted USB flash drive with FIPS-certified hardware encryption, metal construction and built-in cloud backup. It offers strong security features but requires specific Windows drive-letter configuration and lacks password recovery.
The Kingston DataTraveler 100 G3 128 GB offers solid read performance and a convenient sliding cap, but its write speeds and random performance are extremely low, making it best for occasional read-heavy tasks.

Products in the top-left offer the best value (high score, low price).
Professional reviewers acknowledge the drive's solid sequential read capability but criticize its abysmal write and 4K random performance, giving it an AS SSD benchmark score of 0.
Users appreciate the large capacity and easy sliding cap, but many complain about painfully slow write speeds and inconsistent copying.
“Sleek case and worked very nicely for what I needed it for”
“Does exactly what you expect it to do”
“Great product!!!”
Professional reviewers commend the LP50 for its robust, FIPS-certified hardware encryption, user-friendly passphrase mode, and the convenience of built-in USBtoCloud backup, noting that the mandatory drive-letter allocation and absence of any password-recovery option may hinder less-technical users.
Everyday users appreciate the drive's straightforward plug-and-play setup, the confidence of hardware encryption, and the practical metal design with a key loop. Common frustrations revolve around Windows drive-letter conflicts, permanent data loss if passwords are forgotten, occasional slower write performance, and the device warming up.
