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: Very solid scores on this benchmark for the V300 as is typical for drives with the SandForce controller since it employs compressible data. Considering that the read/write specifications are 450MB/s for each, these are some nice numbers.
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 time we see a different outcome when incompressible data is used on the benchmark test, most markedly the write sequential score which dropped considerably. However, the random scores on the smaller files sizes are very good which is where most real world usage would reside. Sequential read scores still exceed the specification of 450MB/s.
Benchmark Results: As evidenced by the graph, performance ramps up as compressibility of data increases as is how the SF-2281 controller operates.
