CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using V7 at the current time.
The ATTO Disk Benchmark performance measurement tool is compatible with Microsoft Windows. Measure your storage systems performance with various transfer sizes and test lengths for reads and writes. Several options are available to customize your performance measurement including queue depth, overlapped I/O and even a comparison mode with the option to run continuously.
Use ATTO Disk Benchmark to test any manufacturers RAID controllers, storage controllers, host adapters, hard drives and SSD drives and notice that ATTO products will consistently provide the highest level of performance to your storage.
AS SSD is a great free tool designed just for benching Solid State Drives. It performs an array of sequential read and write tests, as well as random read and write tests with sequential access times over a portion of the drive. AS SSD includes a sub suite of benchmarks with various file pattern algorithms but this is difficult in trying to judge accurate performance figures.
The official read/write speed for the drive according to the spec sheet is up to 1,000MB/s for both. Testing the drive with the ATTO benchmark we couldn't quite meet that maximum figure for either reads or writes, with the review drive producing a read figure of 970MB/s and writes of 938MB/s. Using the more stressful AS SSD benchmark we saw a read score of 840MB/s with writes at 839MB/s.
Switching to the CrystalDiskMark 7 benchmark, in default mode using incompressible data the best Sequential performance we saw was 904MB/s and 875MB/s for reads and writes respectively. Changing over to compressible data saw the reads rise to 1,017MB/s, slightly faster than the official figure with writes rising to 980MB/s just under the official figure.
Using the Peak Performance profile in CDM7 with compressible data the maximum read score from the drive was 1,016MB/s with writes at 979MB/s. With the Real World profile and the same type of data, the best read/write result was 999MB/s and 964MB/s respectively.
