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 compressible 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.
Using the ATTO benchmark, we couldn't get close to the official maximum read figure of 14,000MB/s with a test result of 12,030MB/s. The write test result was even further away from the official 13,000MB/s at 7,560MB/s. These test results have more to do with the benchmark rather than the drive, as shown by the ATTO 5 results below.
ATTO 5
ATTO 5 has new features, enhancements and changes which allow it to benchmark modern SSDs more thoroughly than previous versions.
Switching to ATTO 5, we got test results of 14,930MB/s and 13,420MB/s for read and writes, respectively, confirming both official maximums. There was a dip in performance for both reads and writes (larger for reads) at the 1MB I/O size, but the drive recovered quickly from it.
