256 GB USB 3.0 flash drive

The SanDisk Cruzer Ultra provides 256 GB of portable storage in a compact black housing. It uses a USB 3.0 interface that is also compatible with USB 3.1 Gen 1 ports. The drive is manufactured in China and carries model number SDCZ48-256G-A46.

Who this suits and who should look elsewhere

This drive suits users who need a simple, high-capacity USB stick for moving large files between laptops and desktops. It is not for buyers who require hardware encryption, ruggedised construction, or a USB Type-C connector.

Deciding specification: USB 3.0 interface

The USB 3.0 specification determines whether this drive will deliver the expected transfer performance on your host device. Systems limited to USB 2.0 will operate at lower speeds, while USB 3.0 or 3.1 Gen 1 ports will enable the full rated throughput.

Questions about this item

What type of USB port does my computer need for the SDCZ48-256G-A46 to function?

The drive requires a USB 3.0 or USB 3.1 Gen 1 port to operate at its intended specification. It will also work in USB 2.0 ports at reduced speed.

Will the SDCZ48-256G-A46 work reliably if I keep using an older USB 2.0 hub?

Yes, the flash drive is backward compatible with USB 2.0 hubs and ports. It will enumerate and transfer data, but throughput will be limited to USB 2.0 maximums.

How can I verify the SDCZ48-256G-A46 is operating at USB 3.0 speeds after plugging it in?

Check the device properties in your operating system to confirm it is connected at SuperSpeed (USB 3.0). Copy a large file and observe sustained transfer rates significantly higher than USB 2.0 limits.
