Ultra Fit 128GB USB 3.1 Drive

The SanDisk Ultra Fit is a compact USB 3.1 flash drive offering 128GB of storage in a low-profile design. It connects via a standard Type A plug and delivers read speeds up to 130MB/s. The drive includes 128-bit AES encryption for file security. It is built for users who want permanent extra capacity on laptops, consoles, TVs or car audio systems without a protruding dongle.

Upgrade from USB 2.0 storage

This drive writes up to 15X faster than standard USB 2.0 drives, cutting large-file transfers to a fraction of the time. A full-length movie can move to the drive in less than 30 seconds. The speed jump is worth it when you regularly shift multi-gigabyte media or backups and want the process to finish quickly. It also replaces bulky portable drives for users who prefer a flush fit.

Check host port and capacity needs

Verify your device has an available USB Type A port compatible with USB 3.1 to reach the quoted 130MB/s read rate; it will fall back to slower speeds on older ports. Ensure 128GB meets your storage target, as the series offers up to 256GB if you need more room. The tiny 0.20 x 0.56 x 1.17 inch form factor sits nearly flush, so confirm adjacent ports stay unobstructed.

Questions about this item

What size USB Type-A port does the 0.20" x 0.56" x 1.17" drive need?

It fits any standard USB Type-A port measuring 0.20 inches wide, 0.56 inches high and 1.17 inches deep.

How do I install the drive and enable the 128-bit AES encryption?

Plug the drive into a USB 3.1 Type-A port; the operating system mounts it automatically, then download the SanDisk SecureAccess software to set a password and activate the 128-bit AES encryption.

When should I replace the drive if I move a full-length movie in under 30 seconds at up to 130MB/s read speed?

Replace the drive if transfer speeds drop well below 130 MB/s read, files become corrupted or the device is no longer recognised by the host system.
