Can anyone explain to me what eSata is and if it can connect to my intel iMac? It says I don't need a firewire/usb2.0 with an eSata but I'm afraid I don't have an adapter for it. 3GBs sounds unheard of. Also, assuming I can't hook it up to my iMac, can anyone direct me to a good firewire enclosure with its compatible hardrive (preferably 250) in separate links? I'm looking at OfficeMax's deal on a 89.99 250GB Seagate and wondering if it would work in MacAlly (or any better ones)'s firewire enclosures. Thx.
