SanDisk Extreme PRO V2 4TB portable SSD

The SanDisk Extreme PRO V2 is a 4 TB external solid-state drive built around a USB 3.2 Gen 2x2 USB-C interface. It delivers NVMe performance with sequential read and write speeds up to 2000 MB/s. A forged aluminium chassis acts as a heatsink to sustain those speeds during heavy workloads. The drive is rated IP65 for water and dust resistance and offers up to 3 metre drop protection.

Creatives needing rugged high-speed storage

Photographers, videographers and field professionals who require fast, durable portable storage for large media files will benefit from the 2000 MB/s throughput and ruggedised enclosure. Hardware-based 256-bit AES encryption helps keep sensitive content private. Users whose workflows are limited to slower USB ports or who need capacities beyond 4 TB should consider alternative solutions.

Plug-and-play with included cables

The package supplies a USB-C to USB-C cable and a USB-C to USB-A cable for broad host compatibility. No driver installation is required on modern operating systems. The SanDisk Memory Zone app enables automated file management and space reclamation after download. Firmware updates should be applied before critical use to ensure optimal performance and compatibility.

Questions about this item

Does my computer need a USB-C port that supports USB 3.2 Gen 2x2 to reach the 2000 MB/s speeds?

Yes, the host must provide a USB 3.2 Gen 2x2 USB-C connection to achieve the advertised 2000 MB/s read and write rates.

Will the drive still operate at full speed if I plug it into an older USB 3.0 Type-A port using the included cable?

The drive will function but speeds will be limited to the USB 3.0 port's maximum bandwidth, well below the 2000 MB/s capability.

How can I verify the drive is delivering the expected 2000 MB/s performance after setup?

Run a sequential read/write benchmark such as CrystalDiskMark on a USB 3.2 Gen 2x2 port; results should approach 2000 MB/s in both directions.
