SanDisk Ultra 64 GB USB 3.0 Flash Drive

This SanDisk Ultra drive provides 64 GB of portable storage with a USB 3.0 interface. It delivers read and write speeds up to 80 MB/s for moving hi-res photos and HD videos. The compact Type-A connector works with USB 2.0 ports as well. SanDisk SecureAccess software adds password protection for private files.

Who this suits and who should look elsewhere

Students and office workers needing quick, pocket-sized file transfers will appreciate the 80 MB/s speeds and SecureAccess encryption. Photographers offloading large RAW batches or videographers moving multi-gigabyte clips may find the write throughput limiting. Users requiring hardware encryption or ruggedised casings should consider other options.

Transfer speed up to 80 MB/s

The headline specification is the 80 MB/s read and write ceiling, which dictates how fast large files move on and off the drive. Real-world throughput will vary by host controller and file type. This figure determines whether the drive matches your workflow for media transfers or document backups.

Questions about this item

Which USB port type on my computer is required for the 80 MB/s read speed?

A USB 3.0 Type-A port is needed to reach the 80 MB/s read speed; the drive will fall back to USB 2.0 speeds on older ports.

Will this 64 GB drive work reliably alongside my existing USB 2.0 flash drives on the same hub?

Yes, the drive is USB 2.0 compatible and will operate on the same hub, though transfer rates will be limited to USB 2.0 performance when connected through a USB 2.0 hub.

How can I verify the drive is delivering the advertised 80 MB/s performance after I plug it in?

Copy a large file to the drive and check the transfer rate in your operating system's copy dialog or run a benchmark tool such as CrystalDiskMark to confirm read and write speeds approach 80 MB/s.
