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 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.
We are using version 4.1 for our NVMe disk tests.
Using the ATTO benchmark we couldn't quite get to the official maximum Sequential figures of up to 12,400MB/s (reads) and up to 11,800MB/s (writes) but the best test results we did get; 11,119MB/s reads (a tiny bit faster than the standard T700), 11,003MB/s writes are the fastest we've seen to date for a consumer drive.
Using the ATTO benchmark, the read performance began to plateau out at 8MB (11,500MB/s), but the write performance levels off way before that, at the 128KB mark with a figure of 11,030MB/s.
