John,
I just completed the newest PPBM6 test for CCloud 2014 with my laptop.....which is ALMOST identical to Bill Gehrke's. One difference is that I have the Crucial M500, ( NOT 550) SSD as the "project drive" for the test and Bill used the Samsung 840 Pro SSD.
He outscored me HUGE in the "disk transfer" test.....he had 495 MB per sec. vs. my 386 MB per sec !!!! I know that the 550 series is faster and that Eric recommends them, but, after seeing these test results, I would lean toward the 840 series...or, even the NEW 850 series, if affordible. I must say the new 2014 CC version of PPro performs INCREDIBLY well on this new laptop....it is like having a top desktop from only a little while ago ....it FLIES through DSLR and other formerly difficult footage like BUTTER....with MANY tracks and effects !
