There's no need to use RAID for swap, it's not like it contains anything |
11 |
of permanent importance. Create a swap partition on each disk and let |
12 |
the kernel use the space as it wants. |

You forgot the data checksumming. If you use hardware RAID then btrfs |
19 |
only sees a single disk. It can still warn you of corrupt data but it |

cannot fix it because it only has the one copy. |

I think there are more important priorities, its not like having a swap |
26 |
partition or two is a hardship or limitation. |
