DataLocker, Inc Sentry 5 128GB USB 3.2 Gen 1 Type A Flash Drive

SKU CH-KS0M-1VSEA

A hardware-encrypted 128 GB USB flash drive with waterproof construction and read speeds up to 260 MB/s

  • Hardware encryption protects data on the drive
  • Password protection restricts access to authorised users
  • Waterproof construction resists liquid damage
  • Read speeds up to 260 MB/s transfer files quickly
  • Write speeds up to 190 MB/s save data fast

Secure portable storage

The DataLocker Sentry 5 provides 128 GB of hardware-encrypted storage in a USB 3.2 Gen 1 Type A flash drive. It targets professionals and organisations that must protect sensitive data while moving files between air-gapped or standard workstations. The drive uses a built-in keypad for PIN entry so no host software is required. It suits users who need FIPS-validated encryption without managing certificates.

Thermals noise and power

The solid-state design has no moving parts, so the drive runs silently and generates minimal heat during normal file transfers. Peak sequential reads reach 260 MB/s and writes reach 190 MB/s, drawing power only from the USB port itself. Typical workloads stay well within the bus power budget, and the waterproof casing adds environmental resilience without active cooling. No fan noise or thermal throttling occurs in standard office use.

Replaces software encrypted drives

This drive replaces USB sticks that rely on host-based encryption software or lack password protection entirely. The jump is worth it when compliance requires hardware AES encryption with a physical keypad, when IT policies forbid installing drivers, or when devices must survive exposure to liquids. It is not suited for users who need capacities beyond 128 GB or who require USB 3.2 Gen 2 speeds for large media workflows.

Questions about this item

How do I set up the hardware encryption on this Sentry 5 drive?

Enter an admin password on the built-in keypad to initialise the drive, then create user PINs; the encryption engine secures all 128 GB automatically

What part of the drive is most likely to wear out first?

The NAND flash cells degrade with each write cycle; the controller spreads wear across the 128 GB, but heavy sustained writes will exhaust the rated endurance first

Which speed limit will I hit first during a long, large-file transfer?

The 190 MB/s maximum write speed is the lower ceiling, so sustained writes will plateau there while reads can reach 260 MB/s
