RAID-5 does not protect you from operating system errors or human
errors.  And the odds of two disks within a single RAID array breaking
within a few days of each other, while very low, are not zero.  RAID-5
is just one more tool in the fight to keep your data highly available.

I backup my data to a USB-attached hard drive, which I only attach when
I am making backups, to reduce the chances that both my primary and
backup drives will both be affected by the same event.  When my backup
drive failed, since I don't have RAID (yet), I was exposed.

I won't personally feel completely safe about my backups until I have
the means to back up my data to tape or optical media (in addition to
backups to a second hard disk) ... maybe Blu-Ray will be my savior,
once the prices come down :-)
