The following chart takes a slightly different angle on Parallel ATA hard drive prices, and attempts to discern overall value using a price per GB figure, and then sorting by it. This chart pushes the lowest $/GB rating to the top, and uses a tried-and-true method of illustrating where the best overall values may exist, Of course, no method is foolproof, and other factors like performance or features certainly come into play, but it does give us a different view on what brands, speeds and capacities offer the best bang for the buck.
The Parallel ATA market continues to keep pace with the SATA market, and we are now firmly into an area where PATA value is owned by the 250GB to 320GB hard drives. Three Western Digital models hold the top spots on the chart this month, with the WD Special Edition 320GB, 300GB and 250GB drives providing the lowest $/GB rating at the highest price/capacity point. The Hitachi 250GB also matches the three Western Digital drives for overall value, but the Western Digital RAID Edition 120GB is at the bottom of the list, with a cost per GB of over 80-cents.
