32 GB USB 3.0 Flash Drive

This 32 GB SanDisk Ultra flash drive uses a USB 3.0 interface to deliver read speeds up to 100 MB/s. It suits anyone who needs a compact, portable way to move documents, photos or videos between computers. The black casing fits standard USB-A ports on laptops, desktops, car stereos and TVs.

Upgrade from USB 2.0 sticks

Moving from a USB 2.0 drive cuts large-file transfer time dramatically, especially when copying multi-gigabyte video folders. The jump is worth it whenever you regularly shift more than a few hundred megabytes at once and your host ports support USB 3.0. If you only handle small text files or use older USB 2.0-only ports, the speed gain will not be noticeable.

Plug-and-play on modern OS

Windows, macOS and Linux recognise the drive instantly with no driver installation required. The most common issue is accidentally leaving the drive in a port during a system reboot, which can cause the BIOS to hang or attempt to boot from it. Always eject the drive in software before unplugging to avoid file-system corruption.
