Dual-port USB flash drive

The SanDisk SDDDC4 is a 128GB USB flash drive with a rotatable metal shell that exposes both a USB Type-C and a USB Type-A connector. It lets you move files directly between USB Type-C smartphones, tablets or Macs and USB Type-A computers without an adapter or cable. The drive is designed for users who need portable, driver-free storage that works across mixed device ports.

Host port and OS check

Before ordering, confirm that your host device has a physical USB Type-C or USB Type-A port and that its operating system supports USB mass storage. The drive uses the USB 3.1 Gen 1 interface for up to 150MB/s read speed, so a USB 3.0 or faster port is required to reach that rate. No separate power supply or driver installation is needed for standard plug-and-play operation.

Sustained transfer behaviour

During long copy operations the drive maintains its USB 3.1 Gen 1 link speed, but actual throughput will vary with file size mix, host controller performance and thermal conditions. The metal housing helps dissipate heat during extended writes, and the rotatable design keeps both connectors protected when the drive is idle. Large sequential transfers stay closer to the 150MB/s read figure than small random ones.
