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. With this version of CDM, we are focused on 4K random performance at QD1 and QD4.






The SU800 delivers superior sequential performance, but that's not what we focus on with CDM. When we turn our attention to random performance at QD1, the SU800 does quite well except when compared with Samsung's 750 EVO. When we directly compare the SU800 to Crucial's MX300, we see that the SU800 has a distinct advantage at low queue depths.




The SU800 delivers the goods where it matters most; QD1. It also displays exceptional random write performance at QD4 which is what we are looking for from a good OS disk. When we directly compare the SU800 to Crucial's MX300, we see that the SU800's SLC caching delivers better overall burst write performance.






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 focus on total score when evaluating AS SSD.






AS SSD is a demanding test. With AS SSD we are looking for a minimum score of 1000 from a TLC SSD. The SU800 gives us what we are looking for at the 256GB and 512GB capacity points. The 128GB model takes a big hit on the read portion of the test where the drive's SLC cache has little to no effect on performance, causing it to deliver an inferior score.
