[...] As someone who recently switched an mdraid to BTRFS (with / on EXT4 on an SSD, which will be migrated at a later point, once I feel more at ease with BTRFS), I was curious about this, so I googled it. I found two threads, [0] and [3], which dispute (and most likely refute) this notion that BTRFS is more susceptible to memory errors than other file systems. While I am far from a filesystem/storage expert (I see myself as a mere user), the cited threads lead me to believe that this is most likely an overhyped/misunderstood class of errors (e.g., posts [1] and [2]), so I would suggest reading them in their entirety.
