I've had a less than pleasant experience with a RAID-1 array this year, running on a desktop chipset controller. A client of me had its server down for two days because one of the disks on the RAID degraded without giving any advice and the second one failed completely. Good thing is the backup was up to date. That teached me on not trust solely on RAID, but keep monitoring disks via a 3rd party app anyway.

I've tried several flavors of chipset based RAID and none gave me a warm fuzzy.
Chipset based solutions try to pull off RAID using very little silicon (space in IC chips).
There is no way it can be as robust as a solution that uses an add-in card which has far more silicon for the purpose.
Add-in cards also have their own monitoring utilities and some (maybe all now) include automated email notification of any problems.
I've been using the RAID1 + BU plan since the 90's in everything except laptops and it's saved the day several times.
Yea. I though first the problem was on the HDDs (brand new Seagates DM series) and poor RAID implementation (although it's a Z77 Asus), but I was to blame since I didn't set up the Intel software that would allow me to keep a close eye on drives' health. My current job made me bit spoiled since I work with new, server-grade equipment (Dell and HP rackservers and blade systems) and forgot I couldn't trust basic SATA drives to have enterprise reliability. 😵
