Serial ATA may be the interface of today, but SATA II/SATA 3.0 Gb/sec. (S2 in our charts) is the future, and the latest drive models are certainly making use of the new standard. Features such as NCQ and a higher overall data bandwidth really help take some SATA drives to a higher performance plane. For our selected brands and sizes, we've gone the same route as with our PATA list, and included everything from a standard 80GB model, to the top-of-the-line 500GB monstrosities and WD Raptor 10K RPM speed demons. As Serial ATA drives are a newer technology, these are decidedly high-end, even at the entry-level, sporting 8MB of cache and 7200 RPM speeds as the base minimum. Our SATA hard drive price list features entries for drives, prices and price changes, and columns for $/GB (cost per GB) and model number.
Once again, even in the face of significant PATA price movement, the Serial ATA chart still showed a higher overall chart drop, and more individual price cuts. The SATA aggregate chart movement was a very healthy $178 drop, which is a bit less than last month, but still very impressive. The individual cuts were not as deep either, but we still have eight that hit double digits, including the Western Digital 500GB (-$26), Seagate 7200.9 500GB (-$21), and Maxtor DiamondMax 11 500GB (-$14) drives. As with the Parallel ATA chart, there is very little upward price movement, with none hitting double digits, and nothing above $7.
