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.
QNAP's official read/write speed for the TS-251B with a 1GbE connection is 112MB/s for both read and writes. Using the ATTO benchmark we squeezed a little more out of the review unit with reads of 119MB/s for both RAIDs 0 and 1. RAID 1 writes came in at 118MB/s, with 117MB/s for RAID 0.
