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: The Vertex 3.20 240GB drive posts some very nice numbers here and slightly above that of the specifications set forth by OCZ. On this benchmark, scores are very close to that of the Vector drive.
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: Par for the course on the SandForce controlled drives, the benchmarks that employ incompressible data have a sizable impact on performance, particularly the writes. That’s evident here with sequential writes falling to 314.70MB/s, a category lead by OCZ’s own Vector drive..
Benchmark Results: This benchmark chart illustrates the impact of data compressibility on performance with performance increasing as the data becomes more compressible.
