As far as I remember there can be spare drives / partitions which will |
| 9 |
replace a failed one if needed. But this does not help if drives / |
| 10 |
partitions fail at the same moment. Under normal conditions spares will |
| 11 |
rise the number of drives which can fail. |

Nothing you asked but I had very bad experience with drives which spin |
| 14 |
down by themselves to save energy (mostly titled green or so). |

Also there has been some talk about SMR |
