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 PRO 480GB's maximum read and maximum write are pinned at 550MB/s and 515MB/s, respectively. According to our tests, these numbers are slightly underrated. It peaked at 559.078MB/s read and 525.057MB/s write in the curves demonstrated in our charts above, which is slightly better than the Extreme II 240GB. Under the curve, its average speed from the very beginning is one of the fastest we have seen; easily cracking the 300MB/s+ mark in both read and write at 4K and above. At 4K and below, its read and write performance was untouchable as well -- even the renowned OCZ Vector 150 and Vertex 460 did not come close in most occasions. The only one that did was SanDisk's own Extreme II, but the Extreme PRO delivers slightly better speed still. SanDisk's Extreme PRO 480GB is also close to one of the highest peaking drives we have here at APH Networks, which is very impressive.
