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 both the Blue 3D and Ultra 3D. At QD4, both drives lead the field. At QD1 only the 850 EVO and the Intel 545s deliver better performance.




The Blue 3D and Ultra 3D both deliver exceptionally strong random write performance at QD1. This is where it matters most, and this is where both drives deliver the goods. The 850 EVO is once again proving to be very hard to match in terms of sheer 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 results.








AS SSD is a demanding test. With AS SSD we are looking for a minimum score of 1000 from a TLC SSD. The Ultra 3D and the Blue 3D are both able to exceed 1150 points. Both outscore their predecessor, the WD Blue, and Intel's 545s, which is also based on 64-layer TLC technology.
