ATTO is a disk benchmark which allows testing of drives with a range of file transfer sizes from 4K up to 2048K. We ran tests with a 1GB span and a default queue depth of 4, which would simulate a fairly intense work environment. The data read and written from ATTO is able to be compressed, which is something Sandforce controllers thrive on, and asynchronous NAND doesn't have much trouble keeping up with synchronous in compressible transfers.
We primarily see that across various file sizes, we see little variance between the performance all of these Sandforce SF-2200 drives. Realistically, the difference between the budget drives and the higher performing (and more expensive) Toggle NAND-equipped drives, such as the renowned Vertex 3 Max IOPS, is essentially null. We also see the Agility 3 taking a firm stance in the 4K file transfers, which is what you often see in normal working conditions. A big plus-one for a budget drive hanging with their heftier brethren, and as it's often stated that you won't notice anything under 10% difference, you won't see a noticeable difference in compressible read/write operations.
