SanDisk Extreme V2 4TB portable SSD

The SanDisk Extreme V2 4TB portable SSD delivers NVMe performance in a compact, rugged enclosure with up to 1050MB/s read and 1000MB/s write speeds over USB 3.2 Gen 2 USB-C. It suits photographers, videographers and mobile professionals who need fast, high-capacity storage that withstands field conditions. The drive includes a carabiner loop for quick attachment and hardware encryption for data privacy.

Upgrade from slower portable drives

This drive is nearly twice as fast as the previous generation, making the jump worthwhile when transferring large media libraries, 4K footage or raw photo batches where transfer time directly affects workflow. It replaces mechanical portable drives that cannot match these speeds or durability ratings. Buyers who need sustained write performance beyond 1000MB/s or capacities above 4TB should look at desktop-class solutions instead.

Check USB-C port and cable compatibility

Verify your host device has a USB-C port supporting USB 3.2 Gen 2 or USB 3.1 Gen 2 to achieve the quoted speeds; older USB-A ports will limit throughput. The box provides a USB-C to USB-C cable and a USB-C to USB-A adaptor for broader connectivity. Ensure your operating system supports exFAT or the file system you plan to use for cross-platform access.

Questions about this item

Does the 2.06 × 3.96 × 0.35 inch drive need a separate mount or power adapter?

The drive is bus-powered over USB-C and requires no external mount or power supply; the carabiner loop is the only built-in attachment point.

Which cable or adaptor do I use first when connecting to a USB-A port, and what is the common mistake?

Plug the USB-C-to-USB-A adaptor into the computer, then the USB-C-to-USB-C cable into the drive; the mistake is inserting the cable into the drive before the adaptor is seated.

What part of the IP55-rated enclosure or the 1500 G shock rating degrades and needs checking over time?

The silicone shell and port seals can wear from repeated drops or grit; inspect them periodically and replace the drive if the seals no longer keep out dust or water.
