Just as in the previous PATA chart, we are also taking a close look at our Serial ATA drives and determining exactly which models and capacities offer the best overall value. We do this through the tried-and-true method of determining hard drive value, or "price per GB", which is then used as a sorting criteria to ensure the best $/GB deals rise to the top. 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 which brands, speeds and capacities offer the best bang for the buck.
The Serial ATA value chart shows the same basic trends, and the 250GB to 320GB range is definitely the place to get the best bang for your buck. It is even more clear with Serial ATA drives than Parallel ATA, as the SATA list shows the top thirteen drives within this range, an unprecedented stranglehold if there ever was one. The Western Digital 320GB also places at the top of the list, and is joined by the Maxtor 250GB as the only two SATA hard drives to dip below the 40-cents per GB level. The low capacity, high-performance Western Digital Raptor 10K drives take up their usual spot at the bottom of the list, but it is interesting to note that while the two older models sport $/GB ratings of over $2. the newer WD Raptor 150GB offers a slightly better value for hardware enthusiasts.
