An EIDE Hard Drive is the least expensive hard drive as of now. (If you don't count the 3 year old IDE hard drives). EIDE hard drives come in UDMA (ATA) 33 and 66. UDMA 66 is much faster than UDMA 33. They also have 2 common rotation speeds, 5400rpm and 7200rpm where the latter is obviously faster. SCSI hard drives are faster and more expensive.
