Ok, so I have a 250GB WD hard disk in my PC. Needless to say, I've run out of space. I'll be buying a new hard disk 750GB~1TB and I'll be fomatting my system as well. So, on which HD should I install my OS? The newer HD will probably have a larger buffer so should I install my OS on that or should I install it on the smaller disk?
Personally, I'd put the OS on the small drive and store all the docs, pics, movies etc on the 750GB drive. That if the OS craps out you haven't lost all your data (although suggest doing regular backups)
Unless you're doing high end graphics or video work, from what I understand, there won't be a noticable performance difference (unless the 250GB is a 4200rpm IDE and the new one is a SATA300!
