Compact 128 GB USB 3.1 drive

The SanDisk Ultra Fit adds 128 GB of extra storage to laptops, tablets, TVs, gaming consoles or car audio systems. Its tiny form factor lets you plug it in and leave it there without blocking adjacent ports. It is ready to use the moment you insert it.

Sustained 130 MB/s read speed

Large files such as full-length movies transfer at up to 130 MB/s, far quicker than USB 2.0. Write performance reaches up to 15x the speed of standard USB 2.0 drives, moving a movie in under 30 seconds. The drive maintains this throughput for everyday backups and media offloads.

Plug-and-stay metal build

The streamlined metal casing measures only 0.6" wide by 0.8" long and weighs 0.3 oz, so it sits almost flush with the host device. A 128-bit AES encryption option via SanDisk SecureAccess protects sensitive files. The drive carries a five-year limited warranty.

Questions about this item

Does the 130MB/s read speed generate noticeable heat during all-day file transfers?

The ultra-compact 0.8-inch body stays cool enough to leave plugged into a laptop or TV continuously; no active cooling is needed.

What host port must my device provide for the USB 3.1 interface to work at full speed?

A USB 3.1 or USB 3.0 Type-A port is required; USB 2.0 ports will fall back to much slower transfer rates.

Will the 0.6-inch width block adjacent ports on an older laptop with tightly spaced USB sockets?

The low-profile 0.6-inch width sits almost flush, so neighbouring ports usually remain accessible even on older machines.
