How would a Btrfs RAID1 array of (equally sized) spinning rust and SSDs work? Will it slow down to the speed of the HDD, or will I get SSD speeds and will the HDD eventually catch up? If not by default, then by option?

For the reading, btrfs currently chooses one of the drives at random, I think based on the PID of the process that's doing the reading. For writing, you have to wait for the slow one.

If you want to mix SSD and hard drives then you probably want bcache.
