Western Digital Black PCIe Gen3x4 NVMe 512GB SSD Review

IOMeter is another open source synthetic benchmarking tool which is able to simulate the various loads placed on hard drive and solid state drive technology.

We test with both random read and write 4k tests, as shown above. There are many ways to measure the IOPS performance of a Solid State Drive, so our results will sometimes differ from manufacturer’s quoted ratings. We do test all drives in exactly the same way, so the results are directly comparable.


The official 4K random read/write figures for the 512GB Black PCIe are 170,000 IOPS and 134,000 IOPS respectively. With our IOmeter test setup we couldn’t match those figures, the tested drive giving 130,539 IOPS for reads and 88,317 IOPS for writes.

Is this the ultimate pinnacle of hard drive engineering?

  • Theyd better be pretty cheap then! I was expecting something somewhere upwards of 200k iops on both read and write… and upwards of 1gb/s on write too…

    Only last saturday I picked up a 250GB Samsung 960 Evo PCIe NVMe. I’ve paired it up with a Asus Gene and a fresh install of Windows and it is blisteringly fast. Is it an absolute must have item for the average user…….probably not, but still, what computer geek considers himself the average user.
