seems like most people who are willing to pay the price premium for sata would be buying more than 40gb
In most cases it's cheaper to buy the larger HD then a smaller one. Deponds on the size. I know I just bought a WD Caviar SE Serial ATA 120 GB SATA 8MB Cache. And I love it. Tho I wish MS would realize a lot of people are tired of Floppys.
Only set me back $150 CDN. And was only 10 more then the EIDE version of it.
The closest thing (sizewise, at least) is a Raptor.
No reason to not get an 80GB drive, they're usually faster, only a little bit more expensive, and have double the storage.
SATA is more of a high-end PC feature so I wouldn't think companies would waste time designing SATA models for the smaller drives. At least this seems to be the marketing theory on the Western Digital website.
I thought that lesser storage = faster access times. Since it wouldn't have to search for every sectors of the disks.
