Just for info: I have a MacBook 2.2ghz, 4gb ram, M-Audio firewire 1814 interface. The 1814 is connected to my computer and I chain my Lacie drive off the interface- works great, no problems. But what I do is pretty simple stuff also- solo fingerstyle guitar, with very few plug-ins, some reverb is about it during recording. I'll "master" with a little EQ and Compression afterwards. Also for the record, I record with this same setup but with a Western Digital Passport external drive(USB) and it works fine as well.
