I burned out a WD drive from Best Buy pretty fast. Took about 6 months of editing heavy efx montages for people to get the read/write speeds down to 40-50mb, so i'm looking for a new one. Are drives like the G-Tech ones worth the money, or would it be better spent getting 2-3 of the cheaper 1TB WD drives? Do you get more time out of the better drives or see that big of a performance difference? I can't see RAID being useful for me, at least at this point in my editing career, but as far as external single drives goes, would a more expensive G-Tech drive be useful compared to "economy" ones? Also are SD cards with high read/write speeds an option for editing these days? I have a rMBP so i'd assume it has a decent transfer rate altho I haven't checked it out yet.
