ATTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted. The test was run with the default runs of 0.5kb through 8192kb transfer sizes with the total length being 256mb.
Benchmark Results: The SandForce drives seem to ramp up a bit earlier as file sizes increase and the overall speeds for reads and writes are better than that of the Marvell controlled Performance Pro drive but bear in mind that this it the best case scenario in terms of data use for the SandForce controllers and not typical of the workload it would see in the real world.
This test employs highly compressible data showing the best case scenario in terms of data throughput for the SandForce drives. We’ll have a look at a few others that use incompressible data to see how that impacts the scores. Highly compressible data is one thing, what happens when we change that?
