Building A Low-Cost Btrfs SSD RAID Array For $80

With the falling prices of solid-state storage, it's becoming increasingly affordable to build a RAID array of SSDs. I have delivered many Btrfs RAID benchmarks on Phoronix over the years while today I have some fresh RAID0 and RAID1 numbers for Btrfs atop the latest Linux 4.5 development kernel when using two low-cost SSDs that retail for just around $40 USD a piece.
