SATA, SCSI Or IDE ???
Written By: Jeff H. ReynoldsAre you confused as to what kind of hard drive to purchase? Do you have a computer and want to upgrade your hard drive or get a larger drive? When you start to search the advertisments and look at the offerings within the local electronic stores, you are going to see a variety of hard drives... different manufacturers and different types of interfaces... including SCSI (small computer system interface) , IDE (Integrated/Intelligent Drive Electronics), and SATA (Serial Advanced Technology Attachment).*
SCSI drives are generally used in servers. Most personal computers don't use scsi interfaces. Rather, the typical PC will have a hard drive utilizing the IDE interface.
In the past two years, we have started to see SATA drives in the market place. They are slowly evolving to replace the more common IDE. Though computer manufacturers have been slow to adopt them in their production lines, SATA drives will likely be standard equipment by 2007 in most machines.
SATA drives are generally regarded as being capable of transferring the most data and the highest rate. Surpassing all other types, including SCSI. SATA also uses a simple cable consisting of a mere 7 wires rather than the 40/80 wire ribbon cable used for IDE drives.
So bottom line is this... if you are looking to replace or upgrade an existing hard drive, odds are that you will need to purchase an IDE type drive. Look for one that has the following specifications: 133 ATA, 7200 rpm. These are the fastest drives in the market place. You are likely to see to some other drives with 100 ATA and/or 5400 rpm specifications. They are fine... but, not the best performers.

* Most all of the IDE drives being marketed today are regarded as being EIDE... that is, Enhanced IDE. Simply put, when drives went beyond 524mb... they became EIDE. They are also a great deal faster than the original IDE. With EIDE, there are several transfer rates common... all the way up to 33MBps (Ultra ATA).
