When I installed Ubuntu 13.04, I managed to combine a couple of outdated askubuntu answers, as well as some of the btrfs documentation in order to figure out how to install Ubuntu over two SSDs using a single btrfs partition (I think /boot was on a small ext4 partition).

I want to install Ubuntu 13.10 in a similar way, using a single btrfs partition striping data over the two SSDs, but I don't feel comfortable synthesizing a method that I am sure will work with current software.

What is the best way to partition and install Ubuntu over two SSDs using btrfs, in an effectively RAID 0 way?

Is the balance command meant to optimize the data over both drives for optimal performance? –  Tom Ato Oct 28 '13 at 3:22
    
No, it just redistributes the (meta/)data across the devices according to the replication policy: read the linked page "Using btrfs with multiple devices" and the FAQ What does "balance" do? –  ignis Oct 28 '13 at 7:45
    
Just as a note (I forgot to mention after installing), I had to make sure to add a few extra megabytes of free space at the beginning of the SSD for GRUB, otherwise it would not have enough space to install. –  Tom Ato Nov 21 '13 at 4:49
