RAID in BTRFS also works very differently to standard raid. The disks are not identical, you can't just read the same location on a second drive.

How can RAID1 give you same disk space as RAID10?
For example RAID1c4 has 4 copies of the data and can survive 3 broken disks.

... RAID1 round-robin read balancing...

The old trick of selection of "which mirrored disk" by "modulo PID" completely ignored the loading on whichever disk...
That old selection by PID may well be fine for a blizzard of small reads for Twits... Too often it was hopeless for media work where one single disk in a cluster would too often suffer a pile-up...
So, this new scheme should undo the need for raid10...
Meanwhile, whatever happened to the patches that were submitted that actually did try to do load balancing?...
Be excellent to one another!
