Ultra-compact 256 GB USB 3.1 drive

This SanDisk Ultra Fit flash drive adds 256 GB of storage in a tiny plug-and-stay form factor. It connects via USB 3.1 and delivers read speeds up to 130 MB/s. The drive includes 128-bit AES encryption for file security. A strap hole allows attachment to a key chain for portability.

Check USB port and space clearance

Verify your device has a USB-A port compatible with USB 3.1 for full speed. The drive measures 0.20" x 0.56" x 1.17" and weighs 0.05 oz, so confirm adjacent ports or surfaces will not obstruct its low profile. No driver installation is required for standard plug-and-play operation.

Suits laptops, consoles and car audio

Ideal for users who want permanent, low-profile storage expansion on laptops, game consoles, TVs or car audio systems. Not suited for buyers who need a USB-C connector, write speeds above the USB 2.0 comparison baseline, or ruggedised waterproof housing. Those requiring hardware encryption beyond 128-bit AES should look elsewhere.

Questions about this item

What is included with the 256GB Ultra Fit drive and do I need any extra accessories?

The package contains the USB 3.1 flash drive itself. Its compact plug-and-stay design fits directly into a USB port, and a strap hole is built in for a key ring if you wish to add one. No separate cable, adapter or software is required.

How do I decide between the 16GB, 32GB, 64GB, 128GB and 256GB versions?

Choose the capacity that matches the amount of data you want to keep on the drive. The 256GB model holds the most files, while the smaller capacities cost less and are sufficient for lighter storage needs. All versions share the same 130MB/s read speed and compact design.

What does the 130MB/s read speed mean when I copy files to my laptop?

It means large transfers finish quickly — a full-length movie can move to the drive in under 30 seconds. Write performance is up to 15 times faster than a standard USB 2.0 drive, so everyday file copies feel noticeably quicker.
