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 latest 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, usually sporting 16MB-32MB of cache and 7200 RPM speeds at the top of the scale. Our SATA hard drive price list features entries for drives, prices and price changes, and a column for $/GB (cost per GB).

The Serial ATA hard drive chart showed much different results, and there were eleven price drops of $10 or more, including some larger ones that hit the Hitachi Deskstar 7K1000 1TB (-$40) and Western Digital RAID Edition2 1TB (-$30) hard drives. On the other end of the chart, only one SATA drive increased in price by more than $2, and even this was only a $10 jump to the Hitachi Ultrastar A7K1000 1TB. The overall chart results showed another very nice result for Serial ATA drive buyers, and the aggregate drop totaled $187 for the month. This is even better news than the $144 total chart decrease we had in January.
