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: As usual, the ATTO benchmark is where the SandForce controllers shine as they take full advantage of the compressible nature of the data being used. As such, it fares very well in the comparison.
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: The AD-SSD benchmark is where the wheels come off a bit as is the case with the SandForce controllers and be limited to the four channels doesn’t help either. The writes drop off considerably but still fast enough to rank midway in the comparison.
Benchmark Results: This is the typical slope we see when data compressibility plays a role in how the drive performs.
