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.
We are using version 3.5 for our NVMe disk tests but will be switching over to version 4, so we’ve included a results chart for this as well.
The official Sequential read/write figures for the 500GB version of the RC500 are up to 1,700MB/s and 1,600MB/s respectively. As you can see from the results chart, we can confirm that write figure but sailed past the maximum read figure at 3,438MB/s.
The reason for this is, as we have seen from the CrystalDiskMark test, the controller in the RC500 seems too much prefer dealing with compressible data when it comes to Sequential reads and as it happens, that’s what ATTO uses to test with, hence the read result.
Using ATTO 4.0 at the default 4-thread setting we saw lower read/write speeds than we saw with ATTO 3.0 at 3,190MB/s and 1,530MB/s respectively. Dropping down the thread depth to 1, the write speed rose slightly to 1,5400MB/s while the read speed dropped to 2,850MB/s.
