My MacBook has a 250GB HD 5400rpm. I also have an external HD 250GB 7200rpm conected via FireWire 400.
Would it make a real difference if I use my external drive for live gigs? Using Live 6 and Reason 4 rewired.

my usb 2.0 hdd takes 5-9 seconds to spinup after it goes to standby. Regular internal drives do too though. Basically no difference.
Unless you're worried about corrupted firewire drivers or something wierd happening I wouldn't worry.

i'd use the external one as it's got faster rpm,

yeah, +1 on the faster rpm making a difference.
i think the latency might be a little higher though (because of firewire), so it depends on the application.
if you could use SATA that would be the best... you could even go so far as to get a 10k rpm external HD via SATA (western digital raptor, for anyone that doesn't know it's THE performance HD for desktops.) i think 15k rpm is available via SCSI (maybe SATA... not sure about that though)

I guess the new raptor is called VelociRaptor. It's fast.
(I figured i should Google it to make sure i knew what I was talking about!)

Oh, and there's nothing faster for SATA.

i would take the 7200 to replace the one in the macbook, and stuff everything on it.

actually i don't think it would make a difference, or a very small one not necessarily in favor for the external, even though the external is faster the bottle neck maybe the FW band width i think your internal connection would be faster, obviously try out some experiments in live with your set and see if the disk indicator thing lights up indicating that it cant get the samples fast enough and go from there, one less thing to complicate your set, and also dont think about dragging your external out with out some power conditioning, some venues have dodgy power so that's another benefit of you laptop battery filtering the power and protecting your drive, but yeah im using Esata external here on a laptop for production

I'm inclined to believe that you're much more like to be burdened by bad driver design or data collisions on your bus than you are by the actual RPM of the drive- that's just the drives ability to physically spin a platter. It seems like RPMs would indicate better access times or transfer rates, but that is not a universal. Take a look at the actual specs on drive latency for more insight.

Only once have I noticed the diff between 5400 and 7200 rpm drives and that was on an old comp w/ 3.5 hdds. The 5400 was noisier and took an extra couple of seconds to load...but on a newer laptop...dunno.
IMO the diff will be negligible. I personally would use the newer drive for storing all my current work and just use the older one for backing up your set/music.
