I just can't afford to do much more than that. If could spring for some quality hardware and run a RAID with 4 or more drives I would and my opinion would probably change.
...but for me.... for home use with just 2 HDDs, it hasn't worked out like I wanted. The final straw was when the RAID controller went crazy, I didn't get any warning it was even happening. The first sign something was wrong was when I tried to access my wedding photos and found the directory was empty!! You can't image the feeling I had in my stomach at that point. After a bunch of troubleshooting I found it was the RAID controller. The Controller had been not fully cloning the drives. At first from the outside all the data was there because the data was at least on one drive... but the controller eventually killed the MFT and that's when I started finding my data gone. (both drives were 100% fine and I'm still using them now).
After using the software "Active File Recovery" for 3 days, I recovered 98% of my data between the two hard drives (100% of the wedding photos recovered). ((each drive had about a 40% data loss)).
Now... before I sound all negative.... there have been a few times where RAID has saved me and I thank it for that.... BUT, what RAID can do for me is the same I can do for myself... and that's duplicate the data between hard drives.
Later on when I'm running 4+ HDDs in RAID and can afford more server class hardware I probably jump back to RAID, but for now my data is too important for me to trust it RAID.
