ATTO
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.
Unconditioned
Conditioned
Between the two drive states, there is a clear difference that the read performance takes more of a hit than the write performance over the drives lifetime, with the read results only seeing up to ~15MB/s degradation. The write results on the other hand see a large fluctuation in margin with the read performance jumping up and down by anything up to 15MB/s as the volume fills up. Considering we would expect to see a more gradual drop in performance, the tests were run again at the 50% level after an additional cooling off period, with similar results experienced each time.
Drive Comparison
For the purpose of drive comparison I use the performance figures from both unconditioned and conditioned tests with 0% data fill.
Out of the box, the M550 is one of the strongest SATA based that we’ve seen to date, nudging just ahead of the HyperX 3K by a small fraction on the read performance.
