I'm thinking about ordering an esata express card for my mbp to use it to connect to my 1tb hdd's to use my 1tb hdd's prowess for some extracting of huge files I deal with and other things.. Anyways, currently I'm using fw800 with my 1tb hdd's its the owc elite pro btw and very fast and awesome external hdd's.. I just purchased the enclosure and put hitachi and seagate 1tb's in them.. Anyways will transferring files via esata be noticably faster than the fw800 that I'm using? Also will I see it performing faster as well via esata say like extracting 15gb files using rar or macpar.. or even say running a osx via esata to the mbp for a 2nd os for some intensive stuff needed for desktop hdds?? If you guys do recommend it which express cards are the best.. I've been looking at apiotek for $39.00 from owc.
