Portable 4 TB SSD for fast media workflows

This SanDisk Extreme Portable SSD V2 stores 4 TB of photos, videos and project files in a compact, rugged enclosure. It targets photographers, videographers and content creators who need quick access to large libraries while travelling or on location. The drive connects over USB 3.2 Gen 2 and delivers up to 1050 MB/s read and 1000 MB/s write speeds for smooth editing and backup. IP55 drip-proof and dust-proof rating adds confidence when working outdoors.

Replaces slower external hard drives

Moving from a mechanical drive or a Gen 1 device to this Gen 2 model cuts transfer times for multi-gigabyte footage and RAW batches. The jump is worth it when your current drive bottlenecks ingest, timeline scrubbing or project duplication. Buyers who need sustained write performance above 1000 MB/s or hardware encryption not listed here should look elsewhere. The Japanese-market firmware and 100 V power specification also mean the unit is not covered by a local warranty.

Check your host ports

The box includes a USB Type-C cable and a Type-A adapter, so verify that your computer, smartphone or console has a matching port for the desired speed. USB 3.2 Gen 2 requires a Gen 2-capable port to reach the rated throughput; older ports will fall back to lower rates. No external power supply is needed, but the product ships with Japanese-language documentation and is built for 100 V environments.

Questions about this item

Does the drive need a separate power adapter or can it run from the USB port alone?

It draws power from the host USB 3.2 Gen 2 port; no external adapter is required.

What is the correct way to connect it so I actually get the 1050 MB/s read speed?

Use the supplied USB Type-C cable directly into a USB 3.2 Gen 2 Type-C port; plugging the Type-A adapter into an older port will drop the speed.

The IP55 rating mentions drip-proof and dust-proof — what does that mean for long-term care?

Rinse off salt or sand with fresh water, dry the connectors fully before plugging in, and avoid submerging the drive.
