Seanmorse79,
I won't disagree that an outer partition will perform better, in fact that was never really the issue.
You are mistaken that the drive itself is the bottleneck. This hasn't been the case for years. A 7200RPM hard drive will typically produce sustained transfer of multiple large file numbers at around 20-30MB/sec. 32 24/96 tracks only require roughy 10MB/sec sustained. That's a lot of data, and most systems will puke out well before that due to bus congestion, poor IDE controller/driver implementation, cpu overload, software inadequacy, soundcard hardware/driver inadequacy (esp low latency drivers), and so on.
I typically work with 24 24bit/44.1khz tracks and I have never had a single dropout due to the hard drive. In fact the hard drive doesn't even come close to a thrashing state.
As was stated above, none of the standalone hard disk recorders require partitioning schemes for performance, and the reason is that 7200RPM ATA drives are quite competent right out of the box.
It's of little benefit to discuss raw benchmark numbers when they are all well above the critical point. I remember when we were all so excited about IDE RAID. 40MB/sec sustained with two drives, sweet! What did we see in real life though? The system choking at the exact same spot it always did, because the single 7200RPM drive was handling the load just fine all along. Sure was fun to look at those huge numbers though.
I agree that two drives is a great way to go, and three is even better. I use my 15GB drive for OS & applications, and my 30GB for audio and scratch. To be honest I never have to think about it.
