What concerns me more than wear is this:

InfoWorld Article:
http://www.infoworld.com/t/solid-state-drives/test-your-ssds-or-risk-massive-data-loss-researchers-w...

Referenced research paper:
https://www.usenix.org/conference/fast13/understanding-robustness-ssds-under-power-fault

Kind of messes with the "D" in ACID.
