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: Given that this is usually the benchmark that yields peak performance, it’s always nice to see a drive far exceed the given specifications which is what we see here from the M500. Still below the SandForce drives in writes but it doesn’t use compression to boost performance.
We have been running the AS-SSD Benchmark app for over some time now and found that it gives a broad result set. The programmer has worked very hard on this software and continues to make updates often so if you use it, show him some love and send him a donation. There are now three tests that are found within the tool and we’ll show the results from two of them.
Benchmark Results: Pretty decent numbers here with a small drop in performance when faced with incompressible data but nowhere near the drop we see with SandForce drives.
Benchmark Results: In contrast to the SandForce drives, performance is very consistent across all levels data compressibility.
