External SSDs with a Thunderbolt 3 interface are still the only option for users looking to get high-end performance in a bus-powered portable device. These SSDs have become possible due to the emergence of NVMe drives in the compact M.2 form-factor, which are fully capable of saturating the Thunderbolt 3 interface, never mind slower interfaces like 10Gbps USB 3.x.

The TEKQ Rapide was one of the first Thunderbolt 3 external SSD that we reviewed. Since it was fairly easy to disassemble, we also presented some benchmarks of a DIY Thunderbolt 3 SSD using the TEKQ enclosure and a SanDisk Extreme Pro M.2 NVMe 3D SSD. Now, since we happen to have Western Digitals WD Black SN750 SSD in, we decided it would be interesting to take a look at the new drive in a similar scenario.
