Portable NVMe storage for creators

The SanDisk Extreme PRO 4TB portable SSD uses NVMe technology to reach sequential read and write speeds up to 2000MB/s over a USB 3.2 Gen 2x2 connection. It is built for photographers, videographers and professionals who move large project files between laptops, desktops, tablets and smartphones. Hardware-based 256-bit AES encryption protects sensitive content without software overhead.

Forged aluminum chassis manages sustained throughput

A forged aluminum body acts as a heatsink so the drive maintains higher speeds during long transfers instead of throttling after a short burst. The metal shell combines with a silicone sleeve to meet IP55 water and dust resistance and survive drops up to two metres, while a carabiner loop secures the drive during travel.

USB 3.2 Gen 2x2 sets the practical ceiling

The USB 3.2 Gen 2x2 interface caps real-world throughput at the rated 2000MB/s, so host ports limited to USB 3.2 Gen 2 or USB 3.0 will run slower. Buyers whose devices only offer USB 3.2 Gen 1 or earlier will not reach the advertised performance. The drive requires a USB-C port capable of 20Gbps to deliver its full speed.

Questions about this item

How noisy or hot does the 2000MB/s NVMe drive get during long transfers?

The forged aluminum chassis acts as a heatsink to sustain performance, and with no moving parts the drive runs silently.

Which port and cable must my laptop already have to reach the 2000MB/s speed?

A USB-C port supporting USB 3.2 Gen 2x2 and the supplied USB-C cable are required for the rated throughput.

Will the IP55-rated 4TB drive work reliably beside my older USB 3.0 hard disks?

Yes, it is backward compatible with USB 3.0 and USB 2.0 ports, though speeds will drop to the older interface limits.
