FutureMark's PCMark 7 Pro has a useful storage benchmark.  It tests read and write patterns of commonly used functions that computer users will encounter regularly.  While most of the other tests show the raw performance of the drives, PCMark helps to translate that performance into how it will affect daily functions.  Among the four 120-128GB SSDs, performance levels were generally similar.  The only real deviation came in the Starting Applications and Importing Photos tests.  Since the Starting Applications test is comprised of a high percentage of small reads with high queue depths, it's no surprise that the clear winner is Crucial's m4.  In the Importing Photos tests, the Mercury EXTREME Pro and Vertex 3 Max IOPS won due to their fast write speeds.

In our Real World File-Copy test, simultaneous reads and writes are tested on each drive.  Each combination of tests comprise of files of different sizes: Movies with one 4.5GB x264 MKV file, MP3s with 270 MP3 files averaging 6.5MB each, and Documents with 16325 document files (various Microsoft Office document files) averaging 100KB each.
