Compact plug-and-stay storage

The SanDisk Ultra Fit USB 3.1 Flash Drive delivers 256GB of capacity in a tiny form factor designed to stay inserted. It suits laptops, game consoles and in-car audio systems that need extra space without a protruding drive. Read speeds reach up to 130MB/s and write performance is up to 15 times faster than standard USB 2.0 drives. A full-length movie transfers in less than 30 seconds.

Fits any USB-A port with no clearance issues

The low-profile housing sits almost flush once plugged in, so it does not block adjacent ports or catch on bags and pockets. It draws power directly from the host and requires no external adapter or driver installation on modern operating systems. Included SanDisk Secure Access software provides password protection with 128-bit encryption for private files. Rescue PRO Deluxe data recovery software is also supplied for accidental deletion scenarios.

Replaces bulky USB 2.0 sticks

Users moving from older USB 2.0 flash drives gain dramatically quicker transfers and a drive that can remain permanently connected. The upgrade is worthwhile when speed matters for large media libraries or frequent backups. It is not suited for buyers who need ruggedised casings, hardware encryption beyond the software layer, or capacities beyond 256GB. Operating temperature spans 0 to 35 Celsius; storage temperature spans -10 to 70 Celsius.

Questions about this item

At what temperature does the drive stop operating safely?

The operating range tops out at 35 Celsius, so sustained use above that risks throttling or shutdown.

Does the tiny casing get hot or draw enough power to be noticeable during all-day transfers?

It runs from the USB port within the 0 to 35 Celsius spec; no fan or heatsink is fitted, so expect warm but silent operation.

Which port type must my laptop or console already have to hit the 130 MB/s read speed?

A USB 3.1 Gen 1 (also labelled USB 3.0) Type-A port is required; USB 2.0 ports will fall back to much lower throughput.
