I went on the ADS site to look at the ext FiWi enclosure (for IDE devices) and, even if they mention "ATA100 support", there's a small tiny note below that says it "supports" it but will not "give" it. It's supposed to give ATA66 though...
My quesiton is: is that relevant if I want to use it as a video storage drive (7200rpm)? Will it "feed" enough to avoid timing gaps?
