One thing to take into consideration is that the max data disk speed on 
drives seems not to be the max speed they can read audio disks, 
especially on older drives.  In my experience, I don't think I've been 
able to rip an audio CD any faster than 6x to 8x, even on my last 
drive, which could *burn* cds at 40x.

So, that would mean 6.4MB/sec + some SCSI bus overhead for 7 drives - 
should work out fine assuming the drives have semi-sane SCSI 

For encoders, I used lame before I switched to encoding things using ogg 
vorbis[1].  I'd say lame is a great mp3 encoder.

I'd say give it a shot, and let us know how it went.

[1] I had disbelief that ogg was a better format than mp3 at first.  I'm 
definately not an audiophile, and generally encode my mp3's at 
128-192kBit/s.  I was impressed - yes, ogg is really that much better.  
The only thing I regret is not having an ogg-compatible portable music 
device other than my laptop, and that's not too convenient to use as
