Save $40 on this price drop. When your workflow involves sensitive data moving between machines, a budget thumb drive stops being a cost saver and starts being a liability.

Kingston Ironkey D500S Encrypted Flash Drive Dual drops to $239.99 - save $40. That 14% discount puts it below the 30-day average of $254.94 and the 180-day average of $243.37.

Get This Deal

For just $239.99, down from its list price of $279.99. This is a meaningful cut for a drive that rarely moves off its sticker. The all-time low sits at $212.30, so there is minor room below this level, but the current price still undercuts the 30-day average by roughly $15. For a piece of hardware with this security pedigree, that gap is worth acting on now rather than waiting for a deeper dip that may not come.

What You're Getting

The D500S packs FIPS 140-3 Level 3 (pending) certification, the flagship standard for government and military-grade storage. It adds brute force and BadUSB attack protection, plus a multi-password option with complex and passphrase modes. The standout is the industry-first dual hidden partition, which lets you run two separate encrypted zones with different passwords. A crypto-erase password wipes the drive on demand in an emergency, and the rugged zinc casing defends against physical penetration attempts.

Who This Is For

This is aimed at IT admins, contractors, and anyone who carries regulated or proprietary data between environments. The dual partition alone makes it a strong fit for separating work and personal files on a single stick.

If your data is all public or you can live with software encryption, a standard flash drive at a fraction of the price does the job.

The Caveat

This is a premium security product, so you are paying for protection rather than raw speed or capacity per dollar. The 256GB tier is the current listing, and buyers who need more room will want to check the larger variants separately.

Final Verdict

The FIPS 140-3 Level 3 certification and dual hidden partition justify the $239.99 price for anyone whose data is worth more than the drive. If you handle sensitive files daily. This is the price to move on.
