SanDisk SDCZ48-064G-A46 64GB Ultra USB 3.0 Flash Drive

SKU CH-5MR3-1Y883

64 GB USB 3.0 flash drive with password protection and USB 2.0 backward compatibility

  • 64 GB capacity stores large files
  • USB 3.0 interface enables fast transfers
  • USB 2.0 compatibility works with older ports
  • Password protection secures private data
  • SanDisk brand delivers reliable flash storage

Capacity & use-case

This 64 GB USB 3.0 flash drive provides portable storage for everyday files, documents and media. It suits students, office workers and anyone who needs quick transfers between computers without relying on cloud services.

Sustained performance

The drive operates on both USB 3.0 and USB 2.0 ports, so transfer speeds scale with the host controller rather than a short burst rating. Under continuous write loads the throughput remains limited by the flash memory and the USB 3.0 interface, not by thermal throttling.

Password protection

Built-in password protection lets you secure sensitive data on the drive itself, making it the deciding feature for users who must meet basic privacy requirements without extra software.

  • 64 GB capacity stores large files
  • USB 3.0 interface enables fast transfers

Questions about this item

Does the 64 GB Ultra USB 3.0 flash drive get hot or draw much power when left plugged in all day?

It runs on standard USB 3.0 bus power with no external supply needed; the compact metal casing stays cool during normal sustained transfers.

What host port and operating-system support do I already need to use the password-protection feature on this drive?

A USB 3.0 or USB 2.0 Type-A port and Windows or macOS with the included SanDisk SecureAccess software installed.

Will this 64 GB Ultra drive work reliably alongside my older USB 2.0 hubs and ports?

Yes — it is backward-compatible with USB 2.0, so it will enumerate and transfer at USB 2.0 speeds on legacy hubs and ports.
