Interesting how bad results you got for brtfs (I guess that MeeGo people
also did some benchmarks, before selecting is as default fs). Maybe
because rather slow cpu in freerunner?

XFS is not prone to power failures anymore or it's not an issue on uSD
(without big cache as normal drives)?

Thanks a lot for benchmark!
