Dang it - I wondered why my work wasn't being taken serious!!!

My Pro Tools HD3 (with 24 inputs and 48 outs) currently has something around a terabyte of hard drives attached to it; all running Firewire800 drives (two are LaCie's, two are, I believe, Rockstor drives). And the other HD3 in my B room has about the same amount of storage space on the external Firewire drives.
I regularly mix sessions with 60-80 simultaneous tracks from those firewire drives; we can go from editing in the B room to mixing in the A room in about 20 seconds (just by unmounting a drive, plugging in the Firewire connection to the other computer and letting it mount). We've even done 96K sessions with more than 24 tracks off of one firewire drive; I simply can't believe that they're too slow, because they work here every day, all day.
Another issue about using the internal drive (besides issues of data backup) is the sheer amount of room that audio data uses; the project I just finished ended up being 48 gig, and that was only one of 4 that are currently being worked on. the internal drive on a macbook would get filled up pretty darned quick....
