Again, the tests today are primarily being put out for reference purposes.

It wasn't long ago that Btrfs RAID 5/6 was deemed unsafe. The kernel code has improved since then and I didn't run into any data loss in this brief benchmarking carried out this round, though as of Linux 4.18 I am not sure if I would quite trust Btrfs RAID 5/6 quite yet if carrying important data.

Using a Btrfs RAID array won't help your build times for large projects like LLVM, but some RAID configurations had in fact slowed it down slightly.

If you want to compare your own Linux system's storage performance to the results found in this article, simply install the Phoronix Test Suite and run phoronix-test-suite benchmark 1808181-RA-SAMSUNGQU08.
