Hybrid HDD + SSD RAID1

Not really security-related at all, but this is just damn cool. After killing three SSDs in 18 months (thankfully the drives were under warranty, but my data wasn't), I went looking for a better solution. When SSDs crap out, they go suddenly and catastrophically. There's no putting them in the freezer or swapping controller boards with another unit like you can with a mechanical hard drive. Once the sector mapping tables - which are constantly being updated due to wear-leveling algorithms - get corrupted, you're pretty much not getting your data back. Turns out there's a simple way to combine the speed benefits of an SSD with the reliability of an HDD-backed RAID1 mirror.
