Compact USB-C storage for daily use

The SanDisk Extreme Fit USB-C Flash Drive adds 256 GB of plug-and-stay capacity to laptops, tablets and other USB-C devices. Its low-profile design sits flush with the port so it does not snag or block adjacent sockets. USB 3.2 Gen 1 delivers read speeds up to 400 MB/s for moving photos, videos and documents quickly. The SanDisk Memory Zone app for Windows and Mac helps organise and back up files.

Best for users who want permanent.

This drive suits anyone who leaves a flash drive inserted while working or travelling and needs a tiny form factor that stays out of the way. It is less appropriate for workflows that demand sustained write performance or the higher throughput of USB 3.2 Gen 2 and later interfaces. Buyers who require ruggedised casing, hardware encryption or a Type-A connector should consider other models.

The deciding spec is the USB 3.2 Gen 1 (5 Gbps)

That specification caps maximum transfer rates at the 400 MB/s read figure quoted for the 256 GB model. If your workflow moves large video projects or disk images and needs faster sustained throughput, this interface will be the bottleneck. For everyday document, photo and media libraries the 5 Gbps link is usually sufficient.

Questions about this item

Is the 256GB version the right choice for large media libraries?

The 256GB capacity stores thousands of photos, videos and documents; the same physical drive is also offered in 128GB and up to 1TB if you need less or more space.

What does the 400MB/s read speed mean when copying files to my laptop?

In everyday use the drive reads at up to 400MB/s over USB 3.2 Gen 1, so multi-gigabyte folders transfer in seconds rather than minutes.

Will the USB 3.2 Gen 1 Type-C connector limit performance on my USB 3.0 port?

The drive uses a USB-C plug at 5 Gbps; on a USB 3.0 Type-A port with an adapter it will negotiate the same 5 Gbps link, so the 400MB/s ceiling remains unchanged.
