External harddrive for sound libraries


New member
Hey guys,

Does using external harddrives for large sound libraries (like Kontakt, Omnipshere) have any downsides when it comes down to performance over internal harddrives?

Also, does it matter if the external harddrive is USB or AC powered? I hear different stories about this. One says that AC powered is a must for performance, the other one says that this is b**shit.
