USB Type-C flash drive for mobile and desktop

The SanDisk Ultra 256GB drive uses a USB 3.1 Type-C connector to plug directly into compatible laptops, smartphones and tablets. Its 256GB capacity stores large media libraries or project files without needing a separate adapter. The slim retractable housing keeps adjacent ports free on compact devices. It is not for users who require a USB Type-A connector or capacities above 256GB.

Passive thermals and bus power only

The drive draws power from the host USB port and has no moving parts, so it produces no audible noise during operation. Surface temperature remains low during typical file transfers because the controller idles between bursts. There is no fan, heatsink or external power requirement to consider. Builders who need active cooling or sustained write workloads beyond the rated speed should look elsewhere.

SanDisk SecureAccess and Memory Zone apps included

The bundled SanDisk SecureAccess software applies 128-bit AES password protection to selected folders on the drive. SanDisk Memory Zone for Android helps organise, back up and recover files stored on the device or in cloud accounts. Both applications install from the drive itself and run without an internet connection. Users who prefer hardware-encrypted drives or third-party backup suites will not benefit from these tools.

Questions about this item

How do I plug the retractable USB Type-C connector into my phone or laptop?

Slide the USB Type-C connector out of the body until it clicks, then insert it into the Type-C port; the slim 0.34" x 0.50" profile leaves room for adjacent ports.

Does the 128-bit AES encryption require any setup after I start using the drive?

Install the included SanDisk SecureAccess software, create a password, and the vault encrypts files automatically; no hardware initialization is needed.

When will the transfer rate drop below the advertised 150 MB/s read speed during a long copy job?

Sustained speeds depend on the host controller, file sizes and thermal limits; the drive has no active cooling, so expect throttling during large sequential transfers.
