Storage Question Options

[xingu]

A simple question:

I've done the good deed and purchased an external firewire drive for my iMac 'studio.' I know I'm supposed to store all audio/song files/projects here rather than my internal drive. My question is, does this "rule" also apply to sample libraries?

For example, I bought a CD that contains 1,000 or so drum loops. I plan on using these both with Reason and directly with Logic. Aside from it being easier to access from a drive rather than a CD, I wanted to copy the files in order to rename them, as they don't currently reflect BPMs. Will storing these on my internal drive cause the same amount of disruption as a song file (i.e. is there any benefit to storing sample libraries on the external drive)?

While I'm at it, should something like an iTunes music folder be taken off the internal drive and ported to the firewire drive as well?
