Conclusion

Super-fast sequential speeds are backed by decent IOPS when under the pump...

A dearth of high-performance third-party controllers has lead to the big storage companies looking inward and design their own. This is why, after years in development, WD has also come to the high-end PCIe NVMe party with its own controller and, in conjunction with Toshiba, access to its own NAND.

The sum of these efforts is the Black NVMe that's available in 250GB, 500GB, and 1TB flavours in the familiar, ubiquitous M.2 2280 form factor. The head honcho, priced at Ā£375, isn't cheap, but it's the going rate for drives of this ilk.

Leveraging these in-house technologies results in a drive that's squarely aimed at the performance enthusiast and digital content creator. Super-fast sequential speeds are backed by decent IOPS when under the pump, and it appears to be a good all-rounder in the premium end of the market.

We'll really know where it fits into the ultra-fast consumer SSD landscape when compared directly against the just-announced Samsung 970 Evo (its natural competitor at $450) and Pro - wait just a little while for that - but we feel that WD has a credible offering for performance junkies.

Do NVMe SSD drives offer real world advantages over SATA3 SSD drives?
Yes - sata3 is limted to 6GB/S NVMe is 16GB/s and higher IIRC
if your doing a lot of reading from the disk then …. loads better

possibly .. not sure on current speeds

Those numbers aren't correct, though close on the SATA.

SATA 3 is capable of 6Gbps (Gigabits per second, not Gigabytes per second.)
NVMe is generally a 4x connection, with a single PCI-E 3.0 lane being capable of around 985MB/s, so roughly 3.95GB/s theoretical maximum.

However, it's not really the maximum bandwidth that shows the biggest improvement over the SATA interface; the improvements are much more extreme when looking at how data can be accessed. SATA wasn't designed with queueing in mind, whereas NVMe was. SATA can handle a single queue, just one, whereas NVMe is capable of 65535. That is where the difference is, usually.
WHY HAVE YOU not listed the benchmarks for the Samsung NVMe drives on the same graphs as these new competitors??????????????????

SO ANNOYING!!

Because this is the worst Hexus “Review” I have ever read. It should be comparing this product to other similar products ie PCIE NVME drives like 960 Evo etc. Did HExus not have any to test?

And Endurance is poor in conclusions.. where is the explanation of that?
