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.
Just by checking out the top of the list, it's easy to see that the 160GB to 200GB range is where PATA hard drives pay off most in terms of overall value. Seagate, Maxtor and Western Digital all have several hard drive models at the top of our list that fit these requirements. A few 250GB models are also inching their way up, but these are still dark horses compared to the 160GB-200GB drives. On the flip side, the old 40GB drives may seem to be value-priced, but once you check out the abysmal price per GB, you will definitely start thinking about upgrading to at least a basic 120GB model.
