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.

Following up next are our 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. As far as the SanDisk controller on two SN730 SSDs in RAID 0 is concerned, well, here are our results. As manufacturer peak read and write performance ratings are usually achievable using ATTO, whether a drive lives up to its marketing claims or not can be validated by this program. Western Digital claims the AN1500 2TB's maximum read and maximum write are pinned at 6500MB/s and 4100MB/s, respectively. The tested results were close to the advertised figures. It peaked at 6130MB/s read and 4190MB/s write. Under the curve, its write speed was very similar to the SN750 1TB until 8KB, where the SN750 held the lead until 64KB and the AN1500 totally pulled away. The read section shared a similar story. The SN750 held the lead between 8K and 256K, then the AN1500 completely dominated the rest. If you look closely, the AN1500 2TB was particularly weak in the 8K to 256K region, because the FireCuda 510 1TB and KC2500 1TB were both also considerably faster. That said, for the most part, the WD_BLACK AN1500 2TB's performance was excellent thanks to its extremely high peak rate for a non-PCIe 4.0 drive.
