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: Solid scores here with the reads and writes both exceeding the specifications put forth by Samsung of 250MB/s & 220MB/s respectively. The 256GB 470 series drive keeps pace with every SATA II based drive in our comparison.
We have been running the AS-SSD Benchmark app for over a year now and found that it gives a broad result set. Many testers are using the 4k file size read/write results for the IO Meter benchmark which is an old tool and the AS-SSD benchmark essentially shows the same metric in its results set. The programmer worked very hard on this software and continues to make updates often so if you use it, show him some love.
Benchmark Results: Again the final numbers exceed expectations and bested nearly every drive in the sequential read/writes. The 4k read/writes weren’t quite as fast as the other drives but they are in the ballpark and as such, the overall score fell a little short of what we see for some of the better drives in the comparison.
