Version and / or Patch Used: 3.05
ATTO is a timeless benchmark used to provide manufacturers with data used for marketing storage products. When evaluating ATTO performance, we focus on the drive's performance curve.
Even in RAID, Optane Memory doesn't possess strong sequential write performance, but not to worry, because sequential write performance is by far the least important of all performance metrics in an OS environment. We will demonstrate this when we get to our moderate workload testing.
Graphing the performance curve demonstrates the low sequential write performance of Optane Memory. At the other end of the spectrum, we have a pair of 950 Pro's in RAID 0 delivering sequential write performance that nearly maxes out the chipset.
2-Optane modules deliver excellent sequential read performance at low queue depths. 3-Optane modules set the bar for low queue-depth sequential read performance through the PCH. Our 3-drive Optane array is maxing out the chipset at 16KB transfers which is something we've not seen a flash array do.
Anvil Storage Utilities
Version and / or Patch Used: 1.1.0
Anvil's Storage Utilities is a storage benchmark designed to measure the storage performance of SSDs. The Standard Storage Benchmark performs a series of tests; you can run a full test or just the read or write test, or you can run a single test, i.e. 4k QD16. When evaluating performance with Anvils, we focus on total score. When evaluating NVMe SSDs, we are typically looking for a minimum total score of over 10K.
Our Optane arrays have no problem easily outscoring the competition because of their otherworldly read performance. You can RAID all the flash based SSDs you want, and they will not be able to come close to the read performance of our Optane Memory arrays.
(Anvil) Read IOPS through Queue Depth Scale
Astonishing random read performance at QD32. Approaching 500K.
This chart perhaps best illustrates what Optane brings to the table. Performance where it matters most in an OS environment. Approximately 70% of all transactions that take place in an OS environment are random reads at low queue depths, with the majority taking place at QD1. At QD 1 both of our Optane Memory arrays are delivering 3-4x the performance of the best that flash has to offer.
(Anvil) Write IOPS through Queue Scale
Our 3-drive Optane array delivers significantly better random write performance than our 2-drive array.
Our Optane arrays may not have good sequential write performance, but they do have what matters most; outstanding random write performance at QD1-2. This is where it is very important for overall system performance to have write-back caching enabled.
