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.

ATTO – Intel Z77 Platform:

Benchmark Results: The performance of the Vertex 450 256GB was only a hair off of the Vector drive and displayed the same dip in performance on the 32K reads.

AS-SSD (1.6.4237.30508) Benchmark – Intel Z77 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 with the Vector, the incompressible nature of the data used in this benchmark has minimal effect on performance unlike that of the SandForce based drives. The LAMD and Samsung powered drives keep pace here.

Benchmark Results: The graph proves out what we referenced above with the performance remaining consistent regardless of the compressibility of the data.
