Seagate IronWolf Pro 18TB (ST18000NE000) HDD Review

Seagate kindly provided us with a pair of IronWolf Pro 18TB drives so we thought we would build them in a RAID 0 array to see what performance boost if any we would get with the drives in this configuration.

In the ATTO benchmark, both read and write performance in the drives in the RAID array was double that of a single drive. In CrystalDiskMark the write performance got a healthy boost from 3.683MB/s up to 8.088MB/s.

In the workload scenarios, the biggest benefit from the drives in an array in terms of bandwidth was in the Web Server test where the single drive produced a figure of 14.14MB/s and the RAID 0 array, 42.85MB/s.

In our throughput test, there was a sudden drop in read performance at the 256KB block mark but the array recovered quickly to finish the test run at 498MB/s.
