Linux software RAID is pretty good. If you have a high-end motherboard the hardware RAID me be faster, but the software RAID is going to be a lot more flexible, and you'll have all the tools for configuring it at your fingertips without having to boot into BIOS.
See the mdadm
man page and the various documentation here.
How do I safely mount /home on that RAID volume?
I'm not sure what you're asking here...mounting a RAID device is just like mounting any other device; you put an entry in your /etc/fstab
file and the system will mount it automatically when it boots. RAID devices are typically named /dev/md0
, /dev/md1
, and so forth, so your fstab
might have an entry like this:
/dev/md0 /home ext4 defaults 0 1
