ATTO Disk Benchmark Results
EDITORS NOTE: ATTO Disk Benchmark is not designed to be used as bandwidth speed tool, as the final results are determined by user-set variables. Benchmark Reviews uses ATTO Disk Benchmark as a tool for illustrating basic IOPS load performance at various chunk load sizes. Please read the Solid State Drive Benchmark Performance Testing article to understand how the benchmarks used in this article should be interpreted.
The ATTO Disk Benchmark program is free, and offers a comprehensive set of test variables to work with. In terms of disk performance, it measures interface transfer rates at various intervals for a user-specified length and then reports read and write speeds for these spot-tests. There are some minor improvements made to the 2.34 version of the program, but the benchmark is still limited to non-linear samples up to 256MB. While the bandwidth results are no realistic for determining the maximum drive speeds, ATTO Disk Benchmark is still a good tool for illustrating the bandwidth at different file size chunks. Please consider the results displayed by this benchmark to be basic IOPS performance indicators.
Beginning with the integrated Intel ICH10R Southbridge chip connected to the G.Skill Titan, the ATTO Disk Benchmark tools performs file transfers ranging from 0.5 KB to 8192 KB. The 128 GB FM-25S2S-128GBT1 shows a 246 MBps read plateau from 128-4096 KB file chunks, while the 167 MBps write performance peaks at 1024 KB. Not surprisingly, these results practically mirror what we received from the OCZ Apex SSD when it was tested.
The G.Skill Titan SSD has the distinct advantage of having two internal SSD controllers to handle the RAID-0 stipe load. G.Skill uses ATTO to define maximum read and write bandwidth for the FM-25S2S-128GBT1 part, which is stated as 200 MBps read and 160 MBps write bandwidth. This seems in-line with the JMicron specification for this architecture, which place the target read speed at 233 MBps and write performance at 166 MBps.
The ATTO Disk Benchmark tool reported an impressive 246 MBps maximum read bandwidth in our tests, and 167 MBps maximum write, making it appear that G.Skill was actually conservative in their product specifications. Because of the MLC construction, and low on-die cache buffer, the G,Skill Titan is best suited for high-performance desktop/notebook platforms.
In our next section, we test linear read and write bandwidth performance of the G.Skill Titan and compare its speed against several other top storage products. Benchmark Reviews feels that linear tests are the best method for testing SSD products, as detailed in our Solid State Drive Benchmark Performance Testing article.
