Serial ATA may be the interface of today, but SATA II/SATA 3.0 Gb/sec. is the future, and the latest hard 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 and 750GB monstrosities, along with the powerful 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.
The Serial ATA hard drive listings showed a slightly lower total chart decrease of $257, but overall trends showed more consistent price cuts contributing to the overall drop, rather than a single $100+ cut like we saw in the PATA chart. There were ten SATA drives that fell by double digits, including the Western Digital Raptor X 150GB (-$44), Seagate 7200.10 750GB (-$27), Hitachi Deskstar 500GB (-$20), and Western Digital RAID Edition 500GB (-$20). Unfortunately, there were a few price increases as well, and both the Western Digital Raptor 74GB and Maxtor DiamondMax 9 120GB jumped by $10 this month.
