You can turn on write back caching if you have a UPS as well (provided your UPS is wired into your system for a graceful shutdown)
Hopefully you have a redundant PS unit. Having a UPS is not going to help if your PS fails.

This might be getting a bit elaborate for a desktop machine. I really want RAID because I'm tired every couple years of hard drive crashes and having to start from scratch and spending a week setting up new drives and getting my design software back on line and trying to recover data.
What do you think of alternative back up systems, such as a tape backup with bare metal restore software? I'd go that route instead if I could fine a solution which would allow me to restore to different hardware, i.e. if my motherboard dies and I need to buy a different brand or model MB. I know Storix back up software has this capability - I use storix on my Linux server with RAID 1. @ home I have one Linux and one Windows desktop machine.
