ATTO & AS-SSD Benchmarks

ATTO v2.47

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: Its interesting how the scores drop off as it reaches the higher files sizes. This is likely a product of the nCache working its magic on the smaller file sizes. Scores topped out at 530MB/s reads and 441MB/s writes which is pretty close to specification.

AS-SSD (1.6.4237.30508) Benchmark – Intel P67 Platform

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: As usual with the Marvell controllers, benchmarks using incompressible data doesn’t have a large impact on performance as we see nice scores here for the SandDisk Ultra Plus. In fact, it lead the way in 4k reads.

Benchmark Results: The graph proves out that the controller is data compression agnostic with performance even across differing levels of compressibility.
