ATTO & AS-SSD Benchmarks

ATTO v2.47

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.

ATTO – Intel Z77 Platform:

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.


AS-SSD (1.6.4237.30508) Benchmark – Intel Z77 Platform:

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.

    Hardly ground breaking performance, but for the price it’s going to be giving samsung a run for their money!

      You’ll have to wait for NVMe drives or other PCI Express solutions to hit the market before you’ll see ground breaking performance again!

      • basroil

        Meant more on the line of 4k performance, but even that is largely limited by SATA interface. Sequential performance in SATA disks is no longer really a test, any good company already maxes out the interface (though reliability tests still are good)

        Once NVMe drives come out into the open market all hell will break loose though, we might see some ridiculous (ly expensive) drives come.
