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 is 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 SandForce based SSDs will perform very well here; as far as the Marvell 88SS9187 is concerned -- well, here are our results. As manufacturer peak read and write performance ratings are usually obtained using ATTO, whether a drive lives up to its marketing claims or not can be validated by this program. SanDisk claims the Extreme II 240GB's maximum read and maximum write are pinned at 550MB/s and 510MB/s, respectively. According to our tests, these numbers are slightly underrated. It peaked at 557.9MB/s read and 521.2MB/s write in the curves demonstrated in our charts above. It recessed from the peak and dipped off a bit near the end though. Under the curve, its average speed from 4K is one of the fastest we have seen; easily cracking the 300MB/s+ mark in both read and write. Only SanDisk's own Ultra Plus and OCZ's flagship Vector SSD even bothered to compete in this area. Although the SanDisk Extreme II 240GB certainly is not the fastest peaking drive we have ever tested using ATTO here at APH Networks, its performance curve is very desirable.
