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: This is the performance we come to expect from the latest generation SandForce controller drives – reads and writes hitting well into 500MB/s territory with a consistent performance gain as file sizes increases until they max out.
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 also typical of SandForce controlled drives where writes drop considerably when faced with data that is more or completely incompressible. In this case, we see that the reads also take a noticeable hit.
Benchmark Results: Usually we see the write performance increase in conjunction with data compressibility but on the mS200, we see a similar occurrence with the reads.
