Yes, all three bananas share one image. This is a first build - problems, beside those documented, could exists.
 
v5.04 / 1.3.2016
Banana M1/PRO/M1+ rebuilded fixed SATA problem set OTG port in HOST mode in vanilla kernel wireless is working on PRO out of the box added utility to switch between OTG and HOST in vanilla kernel Bugs left: OTG mode not working, M1+ wireless not work in vanilla kernel

Hello!
 
I am using BTRFS with Bananian and Armbian. (3 Banana Pies: 4x external USB hard drives, 1x SATA SSD… everything with BTRFS)
 
Armbian with an external SSD (SATA):
root@bananatest:~# uname -a Linux bananatest 4.3.3-sunxi #3 SMP Mon Dec 28 11:27:16 CET 2015 armv7l GNU/Linux root@bananatest:~# dpkg -l | grep btrfs ii  btrfs-progs                     4.2-1                        armhf        Package created with checkinstall 1.6.2 root@bananatest:~# btrfs --version btrfs-progs v4.2 root@bananatest:~# mount | grep btrfs /dev/sda1 on /mnt/BTRFS_POOL_SSD type btrfs (rw,relatime,ssd,space_cache,subvolid=5,subvol=/) /dev/sda1 on /mnt/Data type btrfs (rw,relatime,ssd,space_cache,subvolid=257,subvol=/@Data) root@bananatest:~# cat /sys/block/sda/queue/rotational 0 I am still using btrfs-progs 4.2 (self-compiled). It's working good (compression: lzo and zlib, subvolumes, snapshots, scrub, checksums). If you want to use compression, you should use lzo.
 
With BTRFS I was able to detect a buggy USB hard drive controller.

And you always should keep in mind: 100% of all commonly used benchmarks are just wrong. Without a deeper understanding and an 'active benchmarking' approach you will always end up with misleading results and draw the wrong conclusions.
