Storage strategy. RAID 1 or 5? Backup? Both?

For me, neither.

I need extremely high performance and reliability.  All of my source data resides on an an HDD is backed up, but my OS, apps, and working data is on a pair of SSDs running in RAID 0. I've been running this way reliably for 2+ years.  The system drive is a pair of Intel X25M SATA2 150GB each for a total system drive of 300GB (with Raid 0 you get all of the space.  That gives me READ performance of 500/MBs and write performance a a bit below that with the older drives. lack of garbage collection has not affected the drive's performance at all in all that time.  I don't care if the system drive ever goes belly up - it is unlikely to and its only the system, apps and working data.  Its wicked fast and was easy to set up.  SSDs are now very cheap by comparison - I'd do the same today if I were building a new system and use a pair of SATA3 drives running 500/MBs each to double the performance yet again with a good mid-range OCed Ivy Bridge chip and lots of 1600 RAM.
