Crystal Disk Mark 3.0 is in the spotlight. Crystal Disk Mark is an important benchmark, because it tests the input/output operations per second capability of the storage device. As you can see in our charts above, compared against a few select drives; namely, hard drives from HGST, Seagate, and Western Digital, along with a mainstream MX200 500GB SSD from Crucial, the 5,400RPM Western Digital Blue SSHD WD40E31X 4TB was quite in line with my expectations. Crystal Disk Mark does not account for caching, so it was obviously no contest against the Crucial SSD. For a drive of this caliber, these results were what I was anticipating in the sequential and 512K sections, where it was reminiscent of the Red 4TB, another 5,400RPM drive with four 1TB platters. Like all HDDs in the presence of an SSD, it was blown away in the 4K and 4K QD32 results. That said, the WD40E31X posted some great results in these areas compared to other mechanical disks; delivering a noticeable advantage over the Seagate Desktop SSHD. I will let you take a look at the results in our comparison graphs above.
