Compact plug-and-stay design

The SanDisk Ultra Fit 256GB USB 3.1 flash drive adds storage without protruding from the port. Its low-profile form factor suits laptops, game consoles and in-car audio systems where space is tight. The drive is ready to use immediately after insertion.

Driver-free setup with optional software

Installation requires only plugging the Type A connector into a compatible port; no drivers are needed for basic operation. The 128-bit AES encryption and RescuePRO Deluxe recovery tools are provided via a separate download. Users who skip the software install will not have password protection or file-recovery features enabled.

Suits users needing discreet portable capacity

This drive fits anyone who wants up to 256GB of extra space that stays permanently attached to a device. Buyers who require larger capacities, ruggedised housings or hardware-based encryption without software should look at alternative solutions.

Questions about this item

How can I verify the drive is delivering the advertised 400MB/s read speed after I plug it in?

Copy a large file to the drive and time the transfer; speeds near 400MB/s confirm the USB 3.1 Gen 1 link is active, while much lower rates suggest a USB 2.0 port.

What comes in the package and is any extra cable or adapter required?

The box contains only the 256GB Ultra Fit flash drive itself; its integrated Type A connector plugs directly into a USB 3.0 or 2.0 port with no separate cable needed.

Which capacity in the Ultra Fit line should I pick if I want the 400MB/s read speed?

The 256GB model you are viewing is rated for up to 400MB/s reads; the 128GB version in the same series shares that speed rating.
