Secure USB flash drive for regulated data

The IronKey D500S is a 16GB USB 3.2 Gen 1 Type A drive built around hardware-based XTS-AES 256-bit encryption. It targets government, military and enterprise users who must meet FIPS 140-3 Level 3 (Pending) requirements and data-protection laws such as GDPR, HIPAA, SOX and CCPA. The zinc casing is waterproof, dustproof and crush-resistant with epoxy filling to resist physical tampering.

Practical limits of the USB 3.2 Gen 1 interface

The drive reads at up to 165MB/s and writes at up to 22MB/s over the USB 3.2 Gen 1 connection. These speeds are well below the interface’s theoretical ceiling, so the drive will not saturate the bus on large sequential transfers. The Class 4 rating reflects sustained write performance suited to documents and records rather than high-bitrate media workflows.

Replaces software-encrypted

It upgrades from drives that rely on host-based encryption or offer no hardware protection, removing the risk of keys or plaintext remaining on the host system. The jump is worth it when compliance mandates hardware encryption, tamper evidence and a certified secure microprocessor. Buyers who need higher capacity or faster write throughput for media production should look elsewhere.

Questions about this item

Should I pick the 16 GB D500S or a larger capacity?

The D500S is listed here as a single 16 GB model; no other capacities appear in the product data.

What does the 165 MB/s read speed mean when I plug the drive into my PC?

Up to 165 MB/s is the maximum sequential read rate over USB 3.2 Gen 1; real-world transfers will be lower depending on file size, host controller and system load.

The drive uses USB 3.2 Gen 1 — what does that limit in practice?

USB 3.2 Gen 1 caps the bus at 5 Gb/s, so the 165 MB/s read and 22 MB/s write figures cannot exceed that bandwidth ceiling.
