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 256MB and test both the read and write performance.
Corsair rates the Sequential performance of the 2TB Mini as up to 7,000MB/s and 6,200MB/s for read/writes respectively. With the ATTO benchmark, we couldn't quite get to either of those figures with test results of 6,860MB/s and 5,010MB/s for reads and writes respectively.
Using the ATTO benchmark, the read performance begins to plateau out at an I/O size of 128KB (6,840MB/s) and the performance continues at more or less this level for the rest of the test run. The write performance peaks at the 128KB mark at 5,720MB/s but then drops to 5,260MB/s at 256MB and then runs at around the 5GB/s mark for the remainder of the test.
