CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSDs. We are using V6.0.0. to test HDD drives.

In the CrystalDiskMark 4K QD32 T1 test, the 20TB Exos X20 read test result of 3.218MB/s sees it sitting in fourth place in our results chart. However, its write result of 20.73MB/s is not only the fastest Exos drive write speed we've seen, it's the fastest write speed we've seen to date for a traditional 3.5in hard drive.

Looking at the benchmark result screen we could confirm the official transfer rate of 285MB/s with a Sequential read result of 293MB/s and 289MB/s for writes.
