Especially if you have a separate file system--ideally on separate 
spindles--for each concurrent recording you do and you use an 
appropriate Storage Group Disk Scheduler (such as Combination or 
Balanced I/O--basically just never use "Balanced Free Space" or 
"Balanced Percent Free Space", regardless of how much you think you want 
to :).
