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 we are in the process of upgrading to the 4.0 version so we've included a chart with the drives we have so far tested with the 4.0 version.

The official Sequential read/write figures for the drive are up to 2,400MB/s for reads and up to 1,950MB/s for writes, both figures we can confirm using the ATTO benchmark with the review drive producing read/write figures of 2,452MB/s and 2,064MB/s respectively when tested.

  
The drive scores slightly lower in the 4.0 version of ATTO with reads at 2,280MB/s and writes at 1,920MB/s.
