Intel Optane SSD 905P 960GB AIC NVMe PCIe SSD Review (Page 5)

Version and / or Patch Used: 3.0 Technical Preview

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 QD4. When evaluating CDM results, we focus on 4K random performance at QD1 and QD4.


The impact of patching for spectre/meltdown affects CDM performance more than any other benchmark we run. In-fact patching has an up to 50% negative impact on random performance. Focusing in on QD1 and QD4 we see the 905P destroying our flash-based contenders whether patched or unpatched. Again, we see that the 905P delivers slightly better random performance than the 900P. And again, we will remind you that only the 905P is patched.


SanDisk's Extreme Pro is a write performance juggernaut. It easily wins this test.


Version and / or Patch Used: 1.8.5611.39791

AS SSD determines the performance of SSDs. The tool contains four synthetic as well as three practice tests. The synthetic tests are to determine the sequential and random read and write performance of the SSD. We evaluate AS SSD performance in terms of overall score. We are looking for a minimum score of 2,000 when evaluating NVMe SSDs


The 900P wins this test, just edging out the 905P when running patched. Strangely enough, AS SSD scoring seems to be relatively unaffected by spectre/meltdown patches as evidenced by a slightly higher score than when unpatched. In fact, we've noticed this anomaly with other SSDs as well.
