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: Obviously, the 120GB SanDisk Extreme II drive doesn’t quite have the horsepower of the larger drives with the 240GB faring much better on the writes and the 480GB putting out some impressive numbers overall.

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: All three of the SanDisk drives post a similar overall score although the larger two really do a fair bit better in the writes department and compare favorably with the best drives in the comparison.

Benchmark Results: It’s a little bit redundant to display all three charts but it’s obvious that the compressibility of the data being used plays no factor in the performance.
