Benchmarks Of Btrfs RAID On Four Samsung 970 EVO NVMe SSDs

With the MSI MEG X399 CREATION that we received as part of the launch package for the Threadripper 2950X and Threadripper 2990WX it includes the XPANDER-AERO that provides 4-way M.2 NVMe SSD slots on a PCI Express x16 card. The XPANDER-AERO is actively cooled and could be passed off as a small form factor graphics card upon a very cursory examination. With this card I've been running tests on four Samsung 970 EVO NVMe SSDs in RAID to offer stellar Linux I/O performance. Here are some initial benchmarks using Btrfs.
