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 significant movement, and in contrast to the PATA results, the SATA price drops in May were greater than in April. The aggregate chart decrease totaled a very healthy $277, and there were eleven price drops that reached double digits, up from only eight last month. These individual price cuts also went deeper, the largest hitting the Hitachi Deskstar 500GB (-$44), the Western Digital SE16 500GB (-$28), and Samsung T133 300GB (-$20) hard drives. There was a bit of movement on the price increase side, but only one hit double-digits, as the Western Digital SE16 400GB jumped by $11.
