SanDisk Ultra 64GB USB 3.0 Flash Drive

The SanDisk Ultra SDCZ48-064G-A46 is a 64GB USB flash drive built for everyday file transfers and backups. It suits students, office workers and home users who need portable storage for documents, photos and videos. The drive uses a standard USB-A connector for broad device compatibility.

USB 3.0 interface practical limits

The drive connects via USB 3.0 and delivers read speeds up to 80 MB/s. Actual throughput depends on the host controller, cable quality and file types being transferred. Write speeds are lower than the quoted read figure and will vary with workload. Performance falls back to USB 2.0 speeds when plugged into older ports.

Check your setup before ordering

Verify that your computer or device has a USB-A port available for the connector. The drive measures 0.87" x 0.42" x 0.31" and weighs 13.6g, so confirm physical clearance around adjacent ports. Included SanDisk SecureAccess software requires a compatible operating system for encryption features.

Questions about this item

Which capacity of the SanDisk Ultra SDCZ48-064G-A46 should I choose?

This model is the 64GB version; select it if that capacity matches your storage needs

What does the 80 MB/s figure mean when I copy files to the drive?

It is the maximum read speed the drive can reach under ideal conditions; actual transfer rates will vary with file types and host hardware

What does the USB 3.0 interface cap in practice?

The USB 3.0 connection limits the drive to its stated 80 MB/s peak read speed, so you will not exceed that throughput even on faster ports
