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: As expected, the ATTO benchmark shows the Samsung 840 Pro to be able to kick out some impressive performance numbers. As most know by now, this is generally the benchmark that yields the highest performance results.
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: The 840 Pro took top honors in just about every category and if not, was very close to the lead metric. Since this test uses incompressible data, it’s a very good sign to see that the performance was only mildly diminished from what we saw on the ATTO benchmark.
Benchmark Results: Compressibility of data plays absolutely no role in performance of the 840 Pro as the graph shows a steady state across the range of variable compression levels.
