Friends, I'm sure this has been covered in the past but a "search forums" didn't turn up any current info so here goes: I've got an Intel core duo 2.16 Ghz white case iMac (5,1) from about 2007 which I bought in 2008 refurbed from the Mac Store mainly because I love the (nonmetallic) look and the matte screen. The original HDD (250 GB) is about maxed out and tho the unit has been trouble free from day one, I want to replace the drive with something in the 1TB range. The options seem to be Seagate Barracuda, Hitachi Ultrastar or Deskstar, Western Digital Caviar Black or Samsung Spinpoint. All these drives in my research seem to have lovers and haters. Any recommendations from those of you who have actually replaced the OEM drive with one of these?
