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 match the SATA market, with the overall value ratings moving higher, into the higher-capacity PATA models. It wasn't that long ago that Parallel ATA 160GB to 200GB drives were at the top of the "value chart", and now we find 250GB and 320-GB models holding down the top three spots. The Western Digital SE 320GB is looking like a real steal right now, but there are a couple of 200GB to 300GB drives in the same basic range. The lowest value is reserved for the 80GB drives, although the Western Digital RAID Edition 120GB posts the worst $/GB rating for August.
