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.
Crystal Disk Mark shows similar sequential speeds to that of ATTO. It achieved 562MB/s read and 518MB/s write. 4K read and write speeds show to be very good. It reached over 37MB/s read and 152MB/s write.
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 ADATA Ultimate SU800 achieved an overall score of 1114 points in AS SSD. Sequential read performance came in at just under 523MB/s and write came in at 482MB/s. Looking at 4K QD1 performance, the SU800 is decent. It reached 34MB/s read and 129MBs write and when upping to a higher QD it was able to achieve nearly 81K IOPS read/write. Finally, during the copy benchmark it again delivered decent performance for a TLC SSD.
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, the Ultimate SU800 delivered an average score of 4742 points. It reached nearly 530MB/s read and over 480MB/s write. 4K QD1 performance nearly mirrors our AS SSD results and it was not quite able to reach as high of IOPS as it did in AS SSD.
