Compact 64 GB USB 3.2 Gen 1 drive

The SanDisk Ultra Curve provides 64 GB of portable storage for students, office workers and anyone who moves documents, photos or videos between computers. Its USB 3.2 Gen 1 interface works with existing Type-A ports on laptops, desktops and media players. The lightweight black casing slips into a pocket or bag without adding bulk.

Sustained read speeds up to 100 MB/s

Large file transfers such as video projects or photo libraries complete in a fraction of the time required by older USB 2.0 drives. The controller maintains consistent throughput during extended copy operations rather than throttling after a short burst. Write performance is lower, so the drive suits read-heavy workflows better than constant heavy recording.

Keyring loop and RescuePRO Deluxe offer

A built-in loop lets the drive stay attached to keys or a lanyard, reducing the chance of loss during daily transport. The package includes a download offer for RescuePRO Deluxe software that can recover accidentally deleted files. No monthly fees or internet connection are required to access stored data.

Questions about this item

How much heat does the 64GB SanDisk Ultra Curve generate during continuous file transfers?

The drive has no moving parts and draws power only from the USB port, so it stays cool to the touch even during all-day use.

What host port does the SDCZ550-064G-G46 need to reach its 100 MB/s read speed?

A USB 3.2 Gen 1 Type-A port is required; on USB 2.0 ports the drive works but transfers drop to USB 2.0 speeds.

Will the Ultra Curve work reliably with older USB 2.0 flash drives on the same hub?

Yes, the drive is backward compatible with USB 2.0, so it coexists with older drives on the same hub without conflicts.
