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 SanDisk flash employed on the BPX is slightly slower than the Toshiba flash used on the Patriot Hellfire, which is the reason the BPX is considerably cheaper. However, the difference is only displayed by slightly lower synthetic performance as we will see when we get to our moderate workload testing.


With our configuration, we are getting much better 4K QD1 random read performance than quoted by MyDigital. They quote 35 MB/s; we are getting 47 MB/s, and this is with the drive loaded up with data, which does have a significant negative impact on CDM results.


With this version of CDM, sequential performance is measured at QD1 which is the reason sequential rates are lower than My Digital's quoted numbers which are measured at QD32.




Again, the Hellfire has a slight advantage over the BPX.






Version and / or Patch Used: 1.7.4739.38088


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.






AS SSD is a demanding test, and the BPX has no problem dispatching it with ease. Again, the Hellfire delivers slightly better results. The BPX does manage to outscore OCZ's powerful RD400, and of course the feeble 600p by a country mile.
