I can either purchase an OCZ Agility 3 120GB for $169 or a Crucial m4 60GB for $130, question is which one? I don't really mind about the capacity, but this is an everyday work PC that spends its time shifting 1 - 10 GB .avi's/mkv's around. I also have a 500GB scratch drive (7200RPM Barracuda) and a 2TB WD20EARX as bulk storage. The board is a SATA 6GB/s Asus F1A75 V-PRO. For this type of work, which one?
