Samsung 850 EVO mSATA and M.2 SSD Review


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 Z97 Platform:

Samsung EVO 850 mSATA ATTO Samsung EVO 850 M.2 ATTO

Benchmark Results: The performance on the ATTO is excellent and the mSATA and M.2 drives perform almost exactly like the large 2.5″


AS-SSD (1.7.4739.38088) Benchmark – Intel Z97 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: Again, exactly the same performance we saw with the 2.5″ 850 EVO drives of similar capacity and very well overall. You can’t ask for much more and there aren’t any other drives that do significantly better.

Samsung EVO 850 mSATA 500GB
Samsung EVO 850 M.2 AS-SSD Compression
Samsung EVO 850 M.2 250GB

Benchmark Results: Unsurprisingly, the graph lines are flat showing that data compression has no impact on performance at all.
