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: These are results we would expect to see with a RAID 0 configuration and an interface bandwidth that’s unrestricted. As usual, the SF-2281 controllers shine in this benchmark and bear in mind that the comparison drives are SATA III based.
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: This is where we generally see the write scores dropping off for SandForce controlled drives due to the incompressible nature of the data employed by the benchmark and that’s exactly what we see here with write scores dropping nearly in half but still very fast when compared to SATA III based drives.
Benchmark Results: The gentle slope of the write graph line show that while the compressibility of the data impacts performance, it’s not as dramatic as we’ve seen on a lot of other drives that show a very steep slope.
