[NBLUG/talk] SSD failure rates and RAID

[gandalf at sonic.net]

I have long advocated a second drive with a daily rsync or even local 
backup set vs raid. In my experiences raid 1 generally doesn't just keep 
going during a failure event and due to identical drive use the drives 
tend to fail around the same time.  It is also very important to not 
mistake raid 1 for a backup system. It will happily mirror any sort of 
file corruption (virus, mistakes, hacking) from one drive to the other.
