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 500GB monstrosities and WD Raptor 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.
The Serial ATA hard drive listings showed a bit more activity that the PATA drives this month, and the aggregate price drop surpassed the $200 mark. The individual price cuts were also quite evident, as the Hitachi 500GB dropped $64 and the Western Digital RAID Edition 320GB fell by $56. There were also a few more double-digit price cuts, and these drives stuck to the top-end 300GB and higher range. The only noticeable price spike was a $32 jump in the cost of a Hitachi 400GB, while we also welcomed in the new Western Digital 400GB (with 16MB cache) model to the SATA fold.
