IDE is the old type of Hard drives, they have big cables and are slower,i believe. SATA are the new faster hard drives, and the cables are small, and SCSI are the hard drives with speeds of 15,000Rpm i think. you want a SATA, and either Western Digital or Seagate is fine. if you can afford it, get a raptor.
OK, I just bought a 200GB SATA... I'm going to be replacing my current HD with this new one however I don't have enough time to do it all in one day... So I will have to be switching from the OLD hard drive to the new one several times this week.
Is that OK to do? Will the motherboard cope having a new hard drive a few times a day?
