"Understanding the Robustness of SSDs under Power Fault", FAST '13 [paper]
Horrific. SSDs (including "enterprise-class storage") storing sync'd writes in volatile RAM while claiming they were synced; one device losing 72.6GB, 30% of its data, after 8 injected power faults; and all SSDs tested displayed serious errors including random bit errors, metadata corruption, serialization errors and shorn writes. Don't trust lone unreplicated, unbacked-up SSDs!
