CrystalDiskMark is disk benchmark software that allows us to benchmark 4K and 4K queue depths with accuracy.

 

Note: Crystal Disk Mark 3.0 Technical Preview was used for these tests since it offers the ability to measure native command queuing at 4 and 32.

We are peaking out Haswell's sequential write bandwidth. Haswell's peak sequential read bandwidth is about 1650 MB/s, which we can't quite get to with any of our arrays. We don't have time to check, but I believe with arrays of three to six SSDs, you would achieve close to 1600 MB/s sequential read speed with larger 128k stripes, instead of the 64k stripes we run.

Read performance is very similar for arrays composed of three to six drives, mirroring and confirming our ATTO read performance graph.

Sequential write performance is essentially the same for arrays composed of three to six drives. 4K write throughput increases as drives are added to the array.
