Max IOPS Write

The WD Blue hit (close enough) its factory spec of 100K read IOPS. Write IOPS are 12K lower than factory spec. It does hit 80K plus for about 10 seconds but falls off after that. We test for 30 seconds, which is why the WD Blue failed to finish the test at factory spec.

Iometer – Disk Response

Version and / or Patch Used: Iometer 2014

We use Iometer to measure disk response times. Disk response times are measured at an industry accepted standard of 4K QD1 for both write and read. Each test runs twice for 30 seconds consecutively, with a 5-second ramp-up before each test. We partition the drive/array as a secondary device for this testing.

The WD Blue delivers significantly better read response than the rest of the drives in our test pool including the 750 EVO. Looking at the screenshot, we again see the WD Blue easily surpassing 10K at 4K QD1.

DiskBench - Directory Copy

Version and / or Patch Used: 2.6.2.0

We use DiskBench to time a 28.6GB block (9,882 files in 1,247 folders) composed primarily of incompressible sequential and random data as it's transferred from our DC P3700 PCIe NVME SSD to our test drive. We then read from a 6GB zip file that's part of our 28.6GB data block to determine the test drive's read transfer rate. Our system is restarted prior to the read test to clear any cached data, ensuring an accurate test result.

When testing write transfer rates, we have a rule of thumb. If any SSD cannot achieve 200 MB/s with our write transfer test, that SSD will not receive a TweakTown recommendation. WD's Blue passes with flying colors.
