The SanDisk Extreme 900 is the first external Type-C SSD that we have tested and overall, it is a great performer. Not only does it offer plenty of storage with its 480GB capacity but its performance also puts it on par with many internal solid state drives.

We observed strong results across all of our tests with excellent read/write speeds in ATTO and CrystalDiskMark and strong uncompressed data performance in AS SSD.

It is clear that USB 3.1 has allowed SanDisk to achieve much higher speeds for a portable drive and thanks to the inclusion of a USB Type-A to Type-C cable, the drive is backwards compatible with motherboards that don't feature a USB Type-C port, as well as USB 3.0 and 2.0 though using a lower-spec port will hurt performance.

The SanDisk Extreme 900 Portable SSD is available in three capacities, 480GB, 1TB and 2TB. The drive we tested today was the base model, which comes in at £226.99 on Amazon UK. It's a lot of money for a portable drive but does deliver on the performance side.

Specifically, the SanDisk Extreme 900 peaked at 749MB/sec in ATTO, which is more than 75% faster than any external SSD we've tested before.
