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 larger capacity MX100 is clearly better in the writes department as we see many times with smaller drives but reads for both are strong.

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: Again, writes are weaker for the 256GB drive but overall performance is not far off of what we saw in the ATTO benchmark which means that the controller does an excellent job handling incompressible data.

Benchmark Results: The graphs show what we mention above – incompressible data has no impact on performance and for both drives there is no slope to the graph lines.
