USB 3.0 flash drive

The SanDisk Ultra CZ48 is a 256 GB USB 3.0 flash drive built for everyday file transfers. It suits students, office workers and anyone who moves documents, photos or videos between computers without relying on cloud sync.

SanDisk SecureAccess software

The bundled SanDisk SecureAccess software adds 256-bit AES password protection for selected folders. Private files stay encrypted while the remaining space stays open for quick sharing with family or colleagues.

256 GB capacity headroom

256 GB holds thousands of high-resolution photos, hours of HD video or large project archives. USB 3.0 reads up to ten times faster than USB 2.0, yet write speeds will bottleneck very large single-file transfers or continuous recording workflows.

Questions about this item

Does the 256 GB drive wear out after many write cycles?

Flash memory has a finite number of write cycles, but typical consumer workloads reach that limit only after years of heavy daily use.

What speed ceiling appears first during a long, continuous transfer?

The USB 3.0 interface caps sustained throughput, so large files will not exceed that bus limit once the drive’s internal cache fills.

How warm does the CZ48 get when copying big files all afternoon?

The metal casing dissipates heat from the controller, keeping surface temperature comfortable during extended USB 3.0 transfers.
