Hard Drives for Home Computers If you will be installing a hard drive on your computer, there are three interfaces to know about: SCSI, IDE and Serial ATA. SCSI is used mainly for server systems and is not often found in home computers. The IDE interface is most common in home computers. Serial ATA drives relatively new and are easier to install because they have fewer cables and less configuration required. We give you more information on it.
