Secure portable storage for regulated data

The iStorage datAshur Pro IS-FL-DA3-256-32 is a 32GB USB flash drive built for users who must keep personal or corporate data encrypted at rest. It authenticates with a 7-15 digit PIN entered on an on-board alphanumeric keypad before the drive becomes visible to the host. AES-XTS 256-bit hardware encryption operates in real time with no software installation required. The drive locks automatically when unplugged or after a configurable timeout.

Keypad authentication

The integrated keypad means decryption happens on the device itself, so no password utility runs on the host computer and no trace remains in system memory. A rechargeable battery powers the keypad while the drive is disconnected. The supplied waterproof sleeve raises the ingress rating to IP57, protecting the USB connector and electronics from dust and temporary immersion during transport. The drive is bootable, allowing it to serve as a secure OS or recovery volume.

Verify physical port space

The drive measures 0.41 inches wide by 0.79 inches thick with the sleeve fitted, so adjacent ports on tight hubs or slim laptops may be blocked. Without the sleeve the body is 0.31 inches by 0.71 inches. The internal battery recharges from the USB port; hosts that limit bus power below the USB 3.2 Gen 1 specification could prevent charging and leave the keypad inoperable. Ensure the operating system recognises standard mass-storage class devices without proprietary drivers.

Questions about this item

How often does the on-board rechargeable battery need replacing after repeated PIN entries?

The built-in rechargeable battery powers the keypad for PIN entry; it recharges each time the drive is plugged into a USB port, so no user replacement is required.

Which speed limit appears first during long sequential transfers — the 139 MB/s read ceiling or the 43 MB/s write ceiling?

Sustained writes hit the 43 MB/s ceiling well before reads approach 139 MB/s, making write throughput the first bottleneck.

Does the IP57-rated sleeve and AES-XTS engine raise surface temperature or fan noise during all-day operation?

The drive has no fan and draws power only during active transfers; the IP57 sleeve adds no measurable heat, so it stays silent and cool in continuous use.
