You can get up to 16X SATA PCI-e cards these days for pretty cheap. So as long
as you have the power to run another drive or two there's not much reason not
to do RAID on the important stuff. Also, the SATA protocol allows for port
expanders, which are also pretty cheap.
One of my favorite things about BTRFS is the data checksums. If the drive
returns garbage, it turns into a read error. Also, if you can't do real RAID,
but have excess space you can tell it to keep two copies of everything.
Doesn't help with total drive failure, but does protect against the occasional
failed sector. If you don't mind writes taking twice as long anyway.
