incorrect information here - the sata II 3G
b/s drive is the same as a regular sata drive, the
conection is faster and
may offer other options like ncq, but it is still connected to a regular drive. huge difference between GB/s and Gb/s...
and if you get 2hdds, both being equal, the sata drive will not be faster. they will be the same. sata is just an interface, and it still connects to the same hdd hardware that a ide controller connects to, so a 7200rpm drive is going to be the same as the interface is not the bottleneck, it is the actual mechanics of the drive that are the bottlenecks.
the theoretical capacities for the differnent connectors are as follows - ata100(100MB/s) - ide, ata133(133Mb/s) - ide, sata (150MB/s), sata II/3Gb/s(300MB/s) which is all fine and dandy, but a brand new 7200rpm hdd will only move data at a max str of ~65MB/s, mabye 70MB/s, so you can see that the interface is not the issue. in fact it wasn't until recently that any hdd drive had a str over 100MB/s, which is the newest generation 15K scsi from seagate - the 15k.5.
