After a long wait, the first consumer product with USB 3.1 support is finally here: the Sandisk Extreme 900. This external SSD can reach much higher speeds than the previous generation of external drives, thanks to the new interface. In this review, you'll get to know the 960GB version of this new product.

Thanks to USB 3.1, companies can boost the speed of external devices. While USB 3.0 effectively has an upper limit of around 350 MB/sec, USB 3.1 can push speeds of over 1 GB/sec. Sandisk says that the Extreme 900 can reach a speed of 850 MB/sec for both reading and writing, making it much faster than the Samsung T1 SSDs, which were the fastest external SSDs until now.
