This is a good option if you want to guarantee no data loss (well as long as
you catch it when the first disk goes down). I have over 10TB of data at
work on linux software raid 6 but at home I only raid the boot and system
partitions and keep the video disks as separate drives. One nice thing about
having separate drives for your recordings is that I have them individually
power down when not being used for 5 hours so this saves power.
