Capacity and interface

The SanDisk Ultra Luxe is a 256 GB USB flash drive with a Type A connector and USB 3.2 Gen 1 interface. It is built for anyone who needs portable storage that plugs directly into standard USB-A ports on laptops, desktops or compatible devices.

Software bundle and physical extras

Downloadable software enables 128-bit AES encryption with password protection for sensitive files. The package also includes a licence for RescuePRO Deluxe recovery software and a built-in keyring loop on the all-metal casing for attachment to a keychain.

Who this suits and who should look elsewhere

This drive suits users who want a compact, metal-bodied stick with hardware-backed encryption and file-recovery tools for everyday document, photo or video transfers. Buyers who need a USB-C connector, higher capacities than 256 GB, or ruggedised water and dust resistance should consider other options.

Questions about this item

How long will the 128-bit AES encryption remain effective on the SDCZ74-256G?

The 128-bit AES encryption is a hardware feature of the drive itself and does not degrade or expire with use; it remains effective for the lifetime of the device.

What limits sustained write performance on the USB 3.2 Gen 1 interface?

The USB 3.2 Gen 1 interface caps theoretical bandwidth at 5 Gbps, and the drive's rated read speed is up to 400MB/s; sustained writes will hit the lower of the controller or NAND limits first.

Does the metal casing get hot during all-day file transfers?

The all-metal body acts as a heatsink; it will become warm to the touch during continuous 400MB/s reads but has no moving parts or fan, so it stays silent and within safe operating temperatures.
