Dual-connector 256 GB flash drive

This USB 3.2 Gen 1 drive carries a dual USB Type-C and Type-A connector so you can move files between phones, tablets, Macs and PCs without an adapter. It stores 256 GB of photos, videos and documents. A built-in keyring hole keeps it on your keys or bag. The SanDisk app enables automatic backup of contacts, photos and documents.

Thermals noise and power

The drive has no moving parts and draws power directly from the host port, so it runs silently and adds negligible heat to the device. Read and write speeds both reach 100 MB/s under the USB 3.2 Gen 1 interface. Weighing only 0.03 lb, it does not strain a phone or laptop port during extended transfers.

Replaces single-port OTG sticks

It replaces older OTG drives that offer only a Type-C or Type-A plug, removing the need for a separate dongle when switching between device types. The jump is worth it when you regularly shuffle large media libraries between a USB-C phone and a USB-A desktop. Buyers who need hardware encryption or ruggedised casing should look elsewhere.

Questions about this item

How do I connect the USB Type-C and Type-A ends to my phone and computer?

Flip the drive to expose the USB Type-C connector for your smartphone or tablet, or the USB Type-A connector for your computer. The keyring hole stays accessible in either orientation.

Does the 256GB SanDisk Phone Drive need firmware updates or battery replacement?

No. The drive has no battery and no updatable firmware. Keep the connectors clean and store it on the keyring hole to avoid physical damage.

At what point will sustained transfers slow down on this 100MB/s drive?

Write speed is also rated at 100MB/s, so the flash memory itself is the first limit during long writes. Thermal throttling can reduce throughput during extended use.
