ATTO Disk Benchmark Results

Website: ATTO Disk Benchmark

With Window 7's improved caching technology, our traditional sequential read/write benchmark, FC -Test, was no longer practical to use, due to data being immediately cached and thus invalidating our copy and read performance figures.

Instead, we've opted for ATTO disk benchmark as a straightforward but surprisingly popular tool for testing a hard disk or SSD's ability to deal with reading and writing files of various sizes. The benchmark sequentially writes and reads files varying in size from 0.5KB to 8MB, and can also be adjusted for overlapped I/O and a variety of queue depths, although we've tested using the benchmark's default settings, recording 1,024KB file performance.

ATTO's 256MB benchmark uses extremely compressible data, allowing drives that use compression based storage, such as those based around SandForce's drive controllers, to achieve their absolute maximum performance. This, however, rarely translates into real world performance due to the majority of today's data being at least partially compressed.
