SATA is fast enough. In fact, ATAPI is also fast enough in most
scenarios. It is just that SCSI disks/arrays tend to be of better 
quality (but usually much more expensive).

IIRC Linux's raid support will support hot-swapping disks, but I'm not
sure which disks are are supported. 

An external array with its own CPU doesn't necessarily mean better
performance than one using the host CPU, BTW. Though it will take some
load off of Asterisk. 

And if this is just about redundnacy and not about performance, consider
not buying an expensive array at all, and using two cheap systems. The
cost will be roughly the same, I believe. (RAID= "Redundant Array of
Inexpensive Disks"). Any simple way to achive redundancy here?
