All-metal dual-connector flash drive

The SanDisk Ultra Dual Drive Luxe is a 512GB USB flash drive with both a reversible USB Type-C and a traditional Type-A connector in a single metal housing. It is built for users who move files between modern smartphones, tablets, or Macs and older USB Type-A computers. The swivel design protects both connectors and includes a keyring hole for portability.

For cross-device file transfer.

This drive suits anyone who regularly shifts photos, videos, or documents between USB Type-C and Type-A devices without cables or cloud services. It also supports automatic photo backup via the SanDisk Memory Zone app on Android. Buyers whose devices share only one connector type gain no advantage from the dual-head design and should choose a single-connector drive instead.

USB 3.1 Gen 1 interface with 400MB/s peak read

The drive operates on the USB 3.1 Gen 1 interface and delivers sequential read speeds up to 400MB/s. This specification determines how quickly large media libraries transfer to a computer. If your workflow demands the higher throughput of USB 3.1 Gen 2 or USB 3.2, this model will not saturate those faster ports.

Questions about this item

Does the all-metal housing make the SanDisk Ultra Dual Drive Luxe get hot or draw more power during long file transfers?

The metal casing helps dissipate heat, and USB 3.1 Gen 1 limits bus power so the drive stays cool and draws no more than the port allows even during sustained 400 MB/s reads.

What ports must my phone and computer have for the Type-C and Type-A connectors to work without adapters?

You need a USB Type-C port on the phone or tablet and a standard USB Type-A port on the computer; the swivel design exposes both connectors natively.

Will the drive slow down to USB 2.0 speeds when I plug it into an older laptop that only has USB 2.0 Type-A ports?

Yes, the USB 3.1 Gen 1 interface is backward compatible, so it will operate at the older port's maximum speed instead of the rated 150 MB/s.
