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 both drives complete the benchmark with nearly identical results. Both reach 559MB/s read and just over 490MB/s write. In terms of 4K QD1 performance, both deliver respectable results at 37MB/s read and 146MB/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.
During our AS SSD benchmarks we can see that the 960GB model has a slight lead over the 480GB model. Both have lower performance than seen in the other benchmarks, which is usual. Overall, the 480GB model reached 880 points while the 960GB model reached 1073 points. They reach over 523MB/s read and 466MB/s write. 4K QD1 performance is about 35MB/s read and 124MB/s write. Access times (latency results) are also very good.
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.
Finally, in Anvil we see that the reads are in line with what we have seen in the other tests, however, 4K writes have dropped significantly down to just 81MB/s. Overall, they reached total scores in the mid-3,000 range which definitely lands them in the back of the pack compared to their competition which usually scores over 4-5K in this test.
