This is the HDD I was thinking of getting.
Its an interface technology. However concerning ATA 100 vs. SATA.. Its doing nothing more than say making the bandwidth pipe bigger, by no means does this mean the system will utilize this. Same thing with ATA 100 vs. ATA 66. In most cases the drives will never be able to pump out data at that speed on a consistent basis. The only positive thing about SATA, it saves cable room..
On a system with ATA 100, the hard drive may support this but it will only get about 77mb/s on average. The pipe if you will is too big to be filled completely.
If you want real speed and have money to spare, go with SCSI. (Small computer system interface.) You can buy drives that go up to 15,000 rpm, with those rotation speeds it can achieve higher throughput,
