I just (today) lost a 7-month old hard drive for no apparent reason other than the fact that it decided to turn into a RAW drive and lose it's MFT and MFTMirr.

That being said, I'm RMA'ing the drive--it's a WD 500GB Caviar Black--to Western Digital. When I get the new drive, I'm going to want to set up a RAID 1 array for some redundancy backup.

I also currently have a 500GB Western Digital Green hard drive with some data on it. I have that data backed up on multiple drives (it's all my pictures/music/etc) and through Carbonite, so I can safely format it. My question is: would putting the 500GB WD Green and the 500GB WD Black drives into a RAID affect hard drive performance at all? The Caviar Black is faster and I don't want it to be slowed down by the Green if they are turned into an array.

Can I save ~$50 and RAID these drives, or should I spring for another Caviar Black to keep my performance?

RAID is not a substitute for backup. It protects only from physical drive failures. Chances are if the file system went RAW it was a logical error with the file system, which likely could affect both drives in the RAID volume. RAID is designed for data availability, to be be able to keep on working if one drive physically fails you do not need to stop working while it is being fixed. Logical failures or filesystem failures will result in data loss. There may be a slight performance loss, but RAID1 has some slight hit on performance anyway and I doubt it would be anything you would obviously notice
