Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.
In Crystal Disk Mark the 256GB M600 achieved 523MB/s read and 500MB/s write, while the larger 1TB drive achieved 513MB/s read and 501MB/s write. 4K reads for the 256GB drive reached near 37MB/s and 163MB/s for the 4K writes. The 1TB model got a slightly slower 4k read at around 35MB/s, but scored a slightly better 4k write speed of 169MB/s.
The toughest benchmark available for solid state drives is AS SSD as it relies solely on incompressible data samples when testing performance. For the most part, AS SSD tests can be considered the ‘worst case scenario’ in obtaining data transfer speeds and many enthusiasts like AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.
The 256GB drive reaches an overall score of 1194 with sequential speeds hitting 520MB/s reads and 477MB/s write. 4k speeds are also respectable with the 256GB drive reaching near 35MB/s for 4k read and 127MB/s 4k write.
The 1TB M600’s overall score was 1049 with sequential speeds hitting 511MB/s reads and 478MB/s write. 4k speeds reached 32MB/s for read and 141MB/s for write.
Furthermore, the drives were able to achieve the rated IOPS for each capacity no issue. The 256GB reached 95,734 read IOPS and 80,276 write IOPS at queue depth 64 and the 1TB M600 reached 70,536 read IOPS and 78,674 write IOPS.
In this copy test, it tries to show you how the drive will perform when copying certain types of files. Both drives follow a similar trend in relative performance.
ANVIL STORAGE UTILITIES PROFESSIONAL
Anvil’s Storage Utilities (ASU) are the most complete test bed available for the solid state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing.
In Anvil Storage Utilities the max sequential read reaches 518.88MB/s for the 256GB model and 514.83MB/s for the 1TB model. Sequential write is just shy of the rates specification, coming in at 479.18MB/s for the 256GB model and 475.62MB/s for the 1TB model. When comparing 4K speeds, the 1TB model has a slight 2MB/s read advantage, however, the 256GB model has a slight write speed advantage.
