The ATTO Disk Benchmark performance measurement tool is compatible with Microsoft Windows. Measure your storage system's performance with various transfer sizes and test lengths for reads and writes. Several options are available to customise 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 compressed data.
We are using version 4.1 for our NVMe disk tests with a set length of 256mb and testing both the read and write performance, but we will be switching over to version 5.0.
Using the ATTO 4 benchmark, we couldn't hit the official read and write sequential figures of 9,400MB/s and 8,100MB/s for read and writes, respectively, with test figures of 8,790MB/s for reads and 7,440MB/s for writes.
Using the ATTO 5 benchmark, we could confirm the official maximum read figure with a test result of 9,420MB/s, pretty much bang on the official rating. The write result of 7,790MB/s was some 130MB/s short of the official maximum.
