I have 3 internal Crucial M4s in my main 2600K system and all I can say is that they are flawless. Not a day goes by that they don't impress me. I have a need for an external drive for offsite archiving and I definitely want another Crucial M4 in there. My question is what external case and mechanism should I use to ensure that I get a decent data throughput rate (I deal with multi-GB files on a daily basis). My mobo is a P8Z68-V so I have pretty well every connector known to humanity on the back panel.
