ATTO Disk Benchmark
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.
The read and write performance in ATTO shows some very interesting results across the board. The WD 6TB Red on its own offers some very good performance, but the biggest percentage increase comes in x2 RAID0; the jump from 2 to 3 and then 3 to 4 drives does diminish a little.
