Page 4 - Benchmark: ATTO Disk Benchmark

About 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.

Our next set of tests are the usual ATTO read and write tests. ATTO is an often-quoted benchmark because it is easy to use and accurate. For the most part, it is a favorite among reviewers and I have grown to embrace it as much as the next for the last little while. ATTO uses easily compressible data, so compression-heavy controllers will perform very well here.

The Lexar Professional NM800 PRO 2TB peaked at 6270MB/s write and 6640MB/s read. These are good numbers, but its read speed was well below the quoted 7500MB/s on the box. Under the write curve, it delivered one of the fastest ramp-up curves; well ahead of all of the drives in smaller transfer sizes of 2KB to 32KB including the WD_BLACK SN770 1TB. This was some of the best under-the-curve results we have seen. Its nearest competitor, the ADATA Legend 960, only came close at higher transfer sizes, with the NM800 PRO still staying above. As impressive as the write curve was, the read curve fell in the other direction. Its peak speed was still in the top half of the tested drives, but under the curve the numbers were very mixed. You can see how the graph line was far lower in smaller transfer sizes for read, and the peak speed was reached much later than other drives. Interestingly enough, this behavior was somewhat similar to the XPG Gammix S70 Blade 1TB, which could be explained by the fact both use the same InnoGrit Rainer IG5236 controller. Overall, the results were still good, especially for writing, but the slower below-the-curve read performance was a blemish on what were otherwise good numbers.
