256 GB USB 3.2 Gen 1 Flash Drive

The SanDisk Ultra Curve is a 256 GB USB 3.2 Gen 1 flash drive finished in black. It offers read speeds up to 100 MB/s for moving photos, videos and documents. A built-in keyring loop keeps the drive attached to keys or a bag. The package includes a download offer for RescuePRO Deluxe data recovery software.

Who this suits and who should look elsewhere

This drive suits anyone who wants portable, affordable storage for everyday files and quick transfers between computers. It is not for buyers who need more storage than 256 GB. It is not for users who require hardware encryption or ruggedised construction for harsh environments.

Deciding specification: USB 3.2 Gen 1 interface

The USB 3.2 Gen 1 interface sets the maximum transfer rate at 100 MB/s. This speed handles typical document and media transfers efficiently. Buyers with only USB 2.0 ports will see lower performance. Check that your device has a compatible USB-A port before purchase.

Questions about this item

How long will the 256GB capacity last before I need a larger drive?

The 256GB capacity stores photos, videos and documents; when it fills you can move files to another drive or upgrade to a higher-capacity model such as the 512GB variant.

What limits sustained transfer speed during long copies?

The USB 3.2 Gen 1 interface caps sequential throughput at 100 MB/s read and 100 MB/s write, so large batches will not exceed that rate.

Does the drive get hot or draw much power when plugged in all day?

The lightweight 3-gram design has no moving parts and draws only standard USB bus power, so it stays cool and silent during continuous use.
