SanDisk Ultra 128GB USB 3.0 Flash Drive

The SanDisk Ultra SDCZ48-128G-UQ46 is a USB 3.0 flash drive with a 128GB capacity. It delivers read speeds up to 100MB/s for quick file access. The drive features a black casing and is supplied in new condition. It suits users who need portable, high-capacity storage for everyday file transfers.

Who this suits and who should look elsewhere

This drive suits people who move documents, photos or videos between computers with USB 3.0 ports. Buyers who need write speeds specified by the manufacturer should look elsewhere. Users requiring hardware encryption or ruggedised housing will not find those features here. Anyone needing more than 128GB of capacity must choose a different model.

What to check before ordering

Verify that your device has a USB 3.0 Type-A port to achieve the stated read performance. Confirm the host operating system supports USB mass storage class drivers. Ensure you have a free port and that physical clearance around the port accommodates the drive body. No driver installation is required for standard operation.

Questions about this item

What USB port do I need on my computer to use the USB 3.0 interface on this SDCZ48-128G-UQ46 drive?

The drive uses a USB 3.0 connector and will operate at up to 100MB/s read speed on any USB 3.0 or newer port; it also works on USB 2.0 ports at reduced speed.

Will this 128GB Ultra drive work reliably alongside an older USB 2.0 flash drive I still use?

Yes, each drive enumerates independently on the bus; the SDCZ48-128G-UQ46 will run at USB 2.0 speeds when plugged into a USB 2.0 port while your older drive continues to function normally.

How can I verify the SDCZ48-128G-UQ46 is delivering its rated 100MB/s read performance after setup?

Copy a large single file from the drive to your internal storage and measure the transfer rate with a benchmark tool; sustained reads near 100MB/s confirm the USB 3.0 link is active.
