The ATTO Disk Benchmark performance measurement tool is compatible with Microsoft Windows. Measure your storage system 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 manufacturer's 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. ATTO uses RAW or compressible data.
We are using version 4.1 for our NVMe disk tests with a set length of 256 MB and test both the read and write performance.
Using the ATTO benchmark we couldn't quite get to the official maximum Sequential figures of up to 14,500MB/s (reads) and 12,700MB/s (writes). However, the read-and-write results we did get, 12,970MB/s and 11,800MB/s put the drive into the top spot on the results graph.
Using the ATTO benchmark, the read performance begins to plateau out at I/O size of 128KB (8,780MB/s) but it recovers at 512KB to peak at the 4MB mark at 13,590MB/s before dropping back slightly to finish the test run at 13,530MB/s. The write performance peaks at the 128KB mark at 11,780MB/s and more or less stays there until the end of the test.
