Serial ATA Hard Drives

Serial ATA and the SATA II/SATA 3.0 Gb/s interface is the present and 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 750GB and 1TB monstrosities, along with the powerful Western Digital 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.

Although the chart was hardly on fire, the Serial ATA hard drive listings showed larger price drops and a better overall performance than in Parallel ATA. There was a pair of double-digit price drops, as both the Seagate Barracuda 7200.10 750GB and Hitachi Ultrastar 1TB drives fell by $10. There was a nice selection of smaller price decreases, and other than a $15 spike to the price of the Western Digital RAID Edition 2 500GB, there were few price increases. The August chart totals mirrored this, and the Parallel ATA listings fell by an aggregate total of $43.
