stable storage

Stable storage is persistent storage where data survives:  1. Repeated power failures, including cascading power failures, 2. Single hardware failures (of any board, power supply, etc. but not including media), 3. Repeated software crashes, including reboot cycle, and 4. A minimum number of hours without external power.
