I plan to add a second hard disk to my present home PC configuration. To pick up the right Harddisk, I need some information on compatibility.
My system has a SATA-I controller. I need to know if a SATA-II harddisk will work with a SATA controller (instead of a SATA-II controller).
Secondly, there is the option of a 7200 rpm disk vs. a 10000 rpm disk. The latency and the seek times are nearly half in the faster drive. Will that make a big difference in the performance. I have a 3.0 GHz P4 system with 1.5 GB of RAM.

Your SATA-II drive will mostly work with the SATA-I controller but you will lose out on the benefits of a SATA-II drive (ie you will only get transfer speeds that SATA-I supports). There is usually a jumper setting on the hard disk which makes the controller treat a SATA-II drive as a SATA-I.

For a home PC, you could go with the 7200 rpm drive. You already have a pretty fast processor and good amount of memory. I dont see too many benefits of using a 10K rpm drive.
