CrystalDiskMark

 

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.

The SP550 performs similarly at all capacity points when reading data. The SMI reference design with its A19 Toshiba flash delivers much better 4K QD1-4 performance than the SP550.

As long as the data fits within the SP550's caching layer performance is quite good. The SP550 can deliver very good 4K QD1 write performance.

 

 

AS SSD

 

Version and / or Patch Used: 1.7.4739.38088

 

AS SSD determines the performance of Solid-State Drives (SSD). 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.

The 480GB SP550 delivers a nice score of over a thousand points. Scoring is decent because the test is running within the drives caching layer. The SMI reference design has a little better performance, and that is to be expected because it has a superior flash array.
