Hello! I'm looking to add 3 internal drives (not in a raid) to my new mac pro to use for virtual music instrument software. I've decided to go with either the Seagate 1TB (5yrs warranty) or the Samsung Spindisk 1TB. (3yrs warranty) Would I be better off with the standard Seagate Barracuda 11 or paying a little more for the Enterprise version? (http://www.newegg.com/Product/Produc...82E16822148278) Also, does it matter if you purchase OEM versus retail. As far as I can tell, the only difference is the box they come in? Thanks for any insights!
