Serial ATA may be the interface of today, but SATA II is the future, and the latest drive models are certainly making use of the new standard. Features such as NCQ and a higher overall 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 400GB monstrosities and 10K RPM speed demons. The number of PATA drives may outnumber the SATA selection, but Serial ATA drives are decidedly high-end, even at the entry-level and will sport 8MB of cache and 7200 RPM speeds. Our SATA hard drive price list features entries for drives, prices and price changes, and also columns for $/GB (cost per GB) and model number.
There was a bit more activity on the Serial ATA side of things, with the SATA list posting a slightly larger aggregate price drop. This is also borne out in the most significant drops, with the Western Digital 320GB (-$28), Seagate 400GB (-$26), and Maxtor DiamondMax 10 200GB (-$19) posting the big price cuts of the month. It certainly didn't end there, and we also have three more double-digit price drops, and a host of smaller ones as well. In even better news, there was not a single double-digit price spike this month, and only a few small increases to deal with.
