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. In our run on three different hard drives from three different manufacturers, I found this to be a particular interesting set for discussion, because everyone had its glory, but everyone had its downs as well. Starting from Sequential Read, all three drives came out to be extremely close to each other -- where the Hitachi took the lead, Seagate following closely behind, and Western Digital splitting the difference once again. However, the trend was flipped when the 512K test came. The WD Red turned out to be the fastest in write, but the slowest in read. The Hitachi Deskstar NAS was the complete opposite -- it turned out to be the fastest in write, but the slowest in read. The Seagate NAS HDD came right in between. What gives?

Looking at the IOPS related tests, the WD Red turned out pretty close to the Seagate; being slightly behind in write, but briefly ahead in read. The 7,200 RPM Hitachi was the clear winner here, as it was with the 4K QD32 benchmark in Crystal Disk Mark. The WD Red actually provided quite a bit faster write speed that read speed -- its write speed was actually a hair faster than the speedy Hitachi Deskstar NAS. While it cannot reach its relative-by-marriage in terms of write performance, both results still came out ahead of the Seagate NAS HDD 4TB, as you can see in our graph above.
