I'm considering getting a small SSD for my root fs, but I hear that while 
SSDs can fail read-only, this almost never happens in the wild, and they 
tend to brick themselves instead.  So I want to protect my data.

One scheme I thought of is to have / mirrored between a partition on my 
spinning-rust HD (call it sda2) and one on the SSD (call it sdc1), and have 
the system boot from it while reaping the speed benefits of an SSD.  Is this 
possible?  How would I go about this?  RAID 1?  The synchronization probably 
need not be live, just periodic and frequent.
