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: While it doesn’t take the top spot in any of the scores, it’s darn close and the best performance we’ve seen from a Marvell controlled drive. Very solid.
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: You can see that the performance of the M550 is much more well rounded than that of the M500 with writes not straying too far from the reads while posting an overall score that is second only to the Samsung 840 Pro.
Benchmark Results: The zero slope of the graph lines prove out that data compression plays no role in performance metrics.
