ATTO Disk Benchmark
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. ATTO Disk Benchmark requires that an active partition be set on the drive being tested.
While the bandwidth results are not realistic for determining the maximum drive speeds, ATTO Disk Benchmark is still a good tool for illustrating bandwidth using various file size chunks. Please consider the results displayed by this benchmark to be basic bandwidth performance indicators.
Beginning with the integrated Intel ICH10R Southbridge chip connected to the SATA-II Patriot Torqx SSD, the ATTO Disk Benchmark tools performs file transfers ranging from 0.5 KB to 8192 KB. This 128GB MLC SSD PFZ128GS25SSDR part shows a 258 MBps read plateau from 128-8192 KB file chunks, while the 173 MBps write performance plateaus from 128-8192 KB. This is extremely impressive basic IOPS performance, and exactly what consumers should expect from the Indilinx Barefoot controller on a MLC SSD. These results are inline with those of the Vertex and UltraDrive ME.
Patriot has integrated a 64MB cache buffer into the Torqx SSD, which helps it build speed quickly as it processes small-to-large file chunks. Patriot suggests a maximum read performance of 260 MBps, and write performance topping out at 180 MBps for the 128GB Torqx MLC PE000143-PFZ128GS25SSDR model, and from what we're seeing from ATTO these are very realistic expectations.
In our next section, we test linear read and write bandwidth performance of the Patriot Torqx SSD 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.
