Well no, i don't have data redundancy on my laptop. I Currently have 2x 750GB HDDs in my laptop and i use them as they are (no RAID) and i have a External 2TB HDD which I use backup the data in my laptop to. The backup program i used is apple's "Time machine" and it basically clones the HDDs on my laptop to the External Drive.
Does it have 2 HDD bays or did you have to get a hard drive caddy for your ODD bay?
Still looking for gear. Should I take this somewhere else?
