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.
ATTO 4
Using the ATTO 4 benchmark we couldn't hit the official read and write sequential figures of 14,900MB/s and 14,500MB/s, respectively. The best figures we saw were 13,060MB/s for reads and 13,810MB/s for writes.
ATTO 5
We are also beginning to use ATTO5. ATTO 5 has new features, enhancements and changes which allow it to benchmark modern SSDs more thoroughly than previous versions.
Using ATTO 5, we could confirm the official read figure with a test result that matched it at 14,900MB/s. At 14,090MB/s, the write score was shy of the official maximum by 410MB/s.
