Samsung is significantly faster, the biggest difference in SSD speed/feel comes from 4kb random, QD32/64 results are completely irrelevant, no home use will hit this outside of benchmarks, sequential is nice but ultimately not used much. The samsung is 50% faster in the single most important performance measurement, 4kb random read's.
Still a decent drive for a very good price, the reality is most of us have most of our games and quite a lot of programs on an HDD still, 16mb's random read's is slow for even midrange ssd's, its magnitudes faster than HDD's which can barely break 1mb's.
They would make pretty damn good game storing drives, £100 to fit a pretty large amount of games on with hugely better than hdd performance, and lower power, no noise. Great deal overall, though if you're going for a windows + games type drive, I'd pay the extra and grab a Sammy 830.
