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.






Focusing in on 4K QD1 and 4K QD4, we are getting very strong performance from the SSD 5 545s, WD Blue and 750 EVO. All three are delivering elite performance. Because QD1 performance is more important than QD4, we are giving the win to the 545s because random read performance at QD1 is more important than at QD4.




The Intel SSD 545s is a read centric SSD, so write performance is a secondary consideration as this chart shows. Even so, the write performance we are getting is still quite good. This is what we want to see from a good OS disk. We want it to deliver excellent read performance and still deliver average 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 the 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. A score of 1100 is excellent. It is better than the powerful 730 Series can get. The reason the SSD 5 545s doesn't score higher than some of the less powerful SSDs in our test pool is simply because AS SSD scoring is heavily weighted toward high queue depth performance.
