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 gives us a better look at performance. Sequential speeds are on par with the official specifications, but we can see that 4K performance is a bit lower than we were hoping for. In contrast with what we saw with ATTO, the 4KB performance is a bit lower than the VR180 the VX500 replaces. The 4K read performance at QD1 is very low for a mainstream offering.
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.
In AS SSD the VX500 delivers overall scores of around 1030 – 1050 points. Sequential speeds are around 500MB/s, but again, 4K performance is lower than we were hoping. All models achieved over 90K IOPS read and for write IOPS performance ranged from 55K to 60K. Luckily, the file copy benchmarks there is a notable improvement in performance over the VR180. So that is something to look forward to when we perform some real world benchmarking.
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.
Anvil Storage Utilities also shows us similar results to what we have previously seen. Performance is very close between all the capacities with results giving a slight edge to the larger models. Total scores ranging from 4200 to 4500 were achieved here, placing the VX500 in line with the many mainstream offerings it is competing against.
