SanDisk Ultra 16GB USB 3.0 Flash Drive

This USB flash drive offers 16GB of storage capacity and a USB 3.0 interface for fast file transfers. It suits students, office workers and anyone needing portable storage for documents, photos or videos. The drive is backward compatible with USB 2.0 ports for broad device support. It is not intended for users who require larger capacities such as 32GB, 64GB, 128GB or 256GB.

Thermals noise and power draw

The compact drive measures 0.43" x 0.84" x 2.24" and weighs 0.48 oz, drawing power directly from the USB port without an external adapter. Solid-state construction means silent operation and minimal heat generation during normal read and write activity. No active cooling or fan is required or present. Power consumption scales with the host controller and transfer workload.

SanDisk SecureAccess software and ReadyBoost

The bundled SanDisk SecureAccess software provides 128bit AES encryption with password protection for private files on the drive. ReadyBoost support allows the drive to be used as a cache device on compatible Windows systems to improve system responsiveness. The software runs directly from the flash drive without a separate installation process. No additional accessories such as cables or adapters are included in the package.

Questions about this item

How do I install the SanDisk SecureAccess software that provides 128bit AES encryption on this drive?

Plug the drive into a USB 3.0 port, open the drive in File Explorer, and run the SanDisk SecureAccess installer stored on the drive; the step people skip is creating and confirming the vault password before dragging files into the encrypted folder.

What maintenance or replacement will the 16GB flash memory need later?

Flash memory has a finite number of write cycles; when the drive becomes slow or fails to write, replace the entire unit — there are no user-serviceable parts inside.

At what point does the up to 100MB/s read speed limit show up during sustained use?

The 100MB/s ceiling is the interface maximum; during long sequential reads the controller will saturate at that rate and cannot exceed it regardless of file size.
