This test measures sustained transfer speed on the 13" 2011 MacBook Pro, with the 480GB OWC Mercury Extreme Pro 6G SSD connected to the internal 6G SATA port.

Write and read speed is shown for writing zeroes and for writing pure incompressible data, the worst possible case.

Read speed is almost unaffected by incompressible data, but write speed is less than half of that for writing compressible data (zeroes). In practice however, performance that is write intensive is still mighty impressive, so don’t take these results of out a real world context.

Green/red lines are read/write for zeroes, blue/orange are for incompressible data.
