WD Red 6TB HDD RAID 0 Performance Review

CrystalDiskMark 3.0

CrystalDiskMark is a disk benchmark software that analyses different types of hard drive. Giving sequential benchmark write and read statistics in MB/s. A simple program that is very useful.

CrystalDiskMark 3.0 shows some very big numbers in terms of sequential performance across the different RAID 0 configurations. As with ATTO, the biggest jump in performance comes from a single drive to RAID 0 with 2 drives, but we do find the performance doesn’t diminish as much as it did in ATTO with extra additional drives.

  1. I believe WD’s “Red” series HDDs have a dynamic balancing feature in the main bearings.
    Also, when one of the drives in a RAID-0 array fails, it must be replaced and the
    entire array re-built: this is not much different from the steps that must be taken
    when a single “JBOD” HDD fails. We use a lot of RAID-0 arrays, for speed, and
    we LUV them! Lastly, in future reviews, you might want to mention the ratio
    of (price) / (warranty years). Most often, the 5-year warranties excel on this metric.

  2. Why? Why only synthetic, worthless benchmarks? Of course 2 disks in RAID0 are going to have 2 times everything! We don’t need benchmarks to prove it, logic proves it!

    Why can’t there be one benchmark on the whole Internet, of HDD RAID0 vs no RAID testing real-world scenarios, with a RAID controller (and comparing hardware and software controllers)? And by real-world I don’t mean copying speed as that’s as obvious as synthetic benchmark results.
