  • Fast transfers up to 130MB/s for large files

Capacity and Interface

This SanDisk Ultra flash drive provides 512GB of storage and connects through a USB 3.0 interface rated for up to 130MB/s read speed. It is backward-compatible with USB 2.0 ports and is sold in new condition.

Who this suits and who it does not

The drive suits users who need portable, high-capacity storage for moving large media files quickly between computers with USB-A ports. It is not for buyers who require a USB-C connector, hardware-based encryption, or ruggedised housing for harsh environments.

Deciding specification

The single specification that decides fit is the USB 3.0 interface with up to 130MB/s read performance, which determines whether the drive can meet the transfer-speed requirements of your workflow.

Questions about this item

How can I verify the drive is delivering the advertised 130MB/s read speed after plugging it in?

Copy a large file to the drive and check the transfer rate in your OS file manager or run a benchmark tool like CrystalDiskMark to confirm read speeds approach 130MB/s on a USB 3.0 port.

What accessories or cables are included in the box, and is any extra software required for the encryption feature?

The package contains only the flash drive itself; no cables are needed. The SanDisk SecureAccess software for password protection and encryption is a free download from the SanDisk website.

This model is listed as 512GB — are there other capacities for the same SDCZ48 series and how do I decide which to buy?

The SDCZ48 Ultra range is offered in multiple capacities; choose 512GB if you regularly move large media libraries or full system backups, and pick a smaller size for everyday documents.
