Yup I second that. The SATA 150 Interface bandwidth is hard to completely use with 2 drives, you will definately see a performance gain with the RAID 0 Setup.
On another point of view. . .
With the RAID 0 setup you have a chance of losing all your data, moving the page file over to the second drive (seperating windows and Pagefile) will also give you a performance increase (not as much as RAID 0). Also this will give you 2 drives so you can do disk to disk backups and save yourself some DVDs. . .
Thank you for your input too etomasula. I can't wait until my copy of Vista shows up. Have a great day people!
you could do manual load balancing beyond just the swap file, really. keep any disk io intensive tasks on the second disk and away from the OS and the OS'll be faster.
or for example when video editing is about disk speed and not cpu speed, the output could be on the secondary disk while the input file is on the main one, etc.
Very good practices to note indeed. I also have a 200gb SATA drive that I use for storage already. I also keep the swap file there too. You can never be too careful with your precious data
