SanDisk Ultra Flair 256GB USB 3.0 Drive

The SanDisk Ultra Flair is a 256GB USB 3.0 flash drive built for people who move large files between computers. Its Type A connector fits standard ports on desktops and laptops. The black metal casing protects the drive during daily transport. It suits students and professionals who need quick, portable storage.

128-bit AES encryption and SanDisk SecureAccess

The drive includes 128-bit AES hardware encryption managed through SanDisk SecureAccess software. Users can create a password-protected vault for private files without installing drivers. The software runs directly from the drive on Windows and Mac. This keeps sensitive data secure if the drive is lost or stolen.

256GB capacity with up to 150MB/s read speed

The 256GB capacity holds thousands of photos, documents or several full-length movies. Read speeds reach up to 150MB/s, so large transfers finish quickly. Write speeds are lower, so saving huge single files takes longer. The drive is not suited for running operating systems or applications directly.

Questions about this item

How long does the metal casing typically last before it needs replacing?

The drive uses a durable metal casing designed to handle knocks, and solid-state storage has no moving parts to wear out, so no scheduled replacement is required.

What speed limit appears first during a long, continuous file transfer?

Sustained write speed will settle below the quoted up to 150 MB/s read figure, and the USB 3.0 interface caps theoretical throughput at 5 Gbps.

Does the drive get hot or draw extra power when left plugged in all day?

With no moving parts and a low-power USB 3.0 design, the drive stays cool during extended use and draws only the standard bus power allowed by the port.
