Our Take
A ruggedised pocket-sized external SSD aimed at photographers, videographers, and content creators who need large-capacity fast storage on the move. At 4TB it sits at the high end of the Extreme Portable range, offering a serious capacity upgrade over the more affordable 1TB and 2TB models, though that extra storage comes at a notably steep price premium.
Key Features
Sequential read speeds up to 1,050 MB/s via USB 3.2 Gen 2 (10Gbps interface)
Sequential write speeds up to 1,000 MB/s
Compact, pocket-friendly form factor weighing around 100g
IP55 water and dust resistance rating
2m drop resistance built into the rubberised casing
Includes both USB-C to USB-C and USB-C to USB-A cables in the box
Our Verdict
Ideal for working professionals who regularly shoot high-resolution stills or video and need fast, reliable storage they can pocket on location. If you rarely transfer large batches of files or mostly work at a desk, a cheaper portable SSD or desktop drive will serve you equally well for considerably less money.
