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.

ATTO Read

ATTO Write

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.

  1. I believe WD’s “Red” series HDDs have a dynamic balancing feature in the main bearings.
    Also, when one of the drives in a RAID-0 array fails, it must be replaced and the
    entire array re-built: this is not much different from the steps that must be taken
    when a single “JBOD” HDD fails. We use a lot of RAID-0 arrays, for speed, and
    we LUV them! Lastly, in future reviews, you might want to mention the ratio
    of (price) / (warranty years). Most often, the 5-year warranties excel on this metric.

  2. Why? Why only synthetic, worthless benchmarks? Of course 2 disks in RAID0 are going to have 2 times everything! We don’t need benchmarks to prove it, logic proves it!

    Why can’t there be one benchmark on the whole Internet, of HDD RAID0 vs no RAID testing real-world scenarios, with a RAID controller (and comparing hardware and software controllers)? And by real-world I don’t mean copying speed as that’s as obvious as synthetic benchmark results.
