How many hard drives is too many?

My new system is running great, and today I moved it up to three windows from two to lighten the load on my t60. Right now I have it running a main SATA drive for my OS and primary system, and an IDE drive with another WoW folder for my two secondary windows. So far it seems to be running quite well, noticing a lot less people dropping behind.

That being said, I've been wondering if I should put another hard drive into it. I have a WD Raptor 10k rpm, 80gb hard drive that I'm not using - it should probably even be faster than the main drive for my system. I'm wondering what you guys think - should I drop it in and load one of the accounts on it, to give me one account per drive? I think I'd probably want to put my main on it, seeing as it's the most balls to the wall, and it also wouldn't be slowed down by running the OS off it.

Do you guys think I should mess with it, or just leave things well enough alone since so far things are running smoothly? :huh:

i put in another drive because i heard it would improve my preformance, and after much headache, i got everything loaded onto it like i wanted, only thing if affected for me was the actual loading time when the game starts up or i load into a new zone, nothing else besides that. But if you dont take alot of time loading in i wouldn't mess with it personally, but to each it's own. :)

I ended up purchasing two new hard drives for my system, and quite frankly ended up only using one of my total 3 for wow installations. After finding out about the junction/symbolic link method (NTFS junction points) I see no reason to have installations on multiple drives, save maybe having a single hard drive for every single instance of wow you run. Also, don't run any of the wows at all on your OS hard drive.

Basically, IMO, make one installation and several copies using the above linked method on your secondary hard drive (without the OS on it) and just roll with that. I've had no issues.

I think I'll probably put it in. No sense having a top dollar drive and not using it, besides it will let me move my main WoW install off my OS hard drive, and that can't hurt anything at all.
