Which is the best there 3 popular choices, I just tried Qwix and it's very simple and quick and nothing else to install. The other two you have to install which I'm not crazy about. Unless you guys think Qwix is crap and one of the others is better I might just stick with Qwix.
playing on a softmodded xbox will greatly EXTEND the life of your xbox. It reads form the Hard drive and not the DVD drive which will burn itself out after a sadly short period of time.
I said replaced not removed, i'm talking about 8-10 years from now when the caps are dying. The Hard Drive will fail in a 5-10 years, but if it was only DVD running the hard drive would probably last twice that. Sammy drives are supposed to be the best, but IMHO they tend to fail more often due to the belt issue. Best to try to use it as little as possible.
