[Asterisk-Users] Re: Transfer with Budgetone

I would not recommend software RAID.  My experience is that, if there is 
a reboot resulting from an abnormal shutdown, Linux will recover 
(re-copy) the secondary drive.  This process pegs the processor 
(90-100%) and takes a loooong time.  Of course, voice quality suffers 
when a processor is not available.
