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)...
Force GS: Sandforce
Intel 520: Sandforce
Vertex 4: Last Gen Marvell (with Indilinx Firmware)
The first thing that stands out about the results above is that all of the drives being tested pretty much max out our SATA3 port on X79, which is great. When we then look at write speeds the various models with their memory and controller differences begin to spread out and we note that the Plextor drive performs well at 460MB/s however many of the other drives are hitting 500+.
