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 are usually far more active than the Parallel ATA chart, but this month showed a big change. The aggregate SATA chart drop was only $108 this month, a far cry from last month's -$252, and well back of even the PATA chart performance. The individual price drops were also less impressive, with the Western Digital Raptor X 150GB 10K (-$36), Western Digital RAID Edition 500GB (-$34), and Western Digital Raptor 150GB 10K (-$28) drives representing the largest monthly decreases. Unfortunately, the price increases were also a bit more active, and there were a trio of double-digit spikes, including a $20 jump to the price of the Seagate Barracuda 7200.10 750GB.
