ATTO disk benchmark allows us to run a synthetic test on the various drives which are being tested today, letting us see the peak speed achieved on each model.
As a quick reminder, the controllers in each are as follows (latest gen unless stated)...
The first thing that stands out about the results above is that the read speed on the M5M drive is right up there with desktop equivalents. We are seeing almost full SATA 6GB/s performance here and when we look at write performance we find that this 128GB model hits its rated speed (256GB = 430MB/s, 128GB = 320MB/s, 64GB = 160MB/s). That is not far off a mainstream desktop SSD in the form of the Corsair Neutron and well in excess of a standard mSATA model, the Intel 310 Series.
