I am in the same position. I am transitioning from a singel BE/FE to 
dedicated BE and multiple FE's
I am about to upgrade from a single SATA 300  to an array.  I figure I 
need redundancy simply because I will have 4 drives and the odds of a 
failure in the next 24 months are reasonably high and I wouldn't like to 
lose all that content

Currently, all the regular TV shows are set to automatically transcode 
to mpeg4.  For Movies, I make sure the cutlist is correct and manually 
transcode to mpeg4.

Anyone who has a large raid-5 array happy with the performance?  I have 
to look into it, but can transcode be set to use a different disk for 
it's temporary files ( perhaps a ramdisk for /tmp ) ?
