Any controller that claims RAID10 on a server with 6 drive bays should |
| 11 |
be able to put all six drives in an array. But you'll get a three-way |
| 12 |
stripe (better performance) instead of a three-way mirror (better fault |
| 13 |
tolerance). |

So, |

The former gives you more space but slightly less fault tolerance than |
| 27 |
four drives with a hot spare. |
