A bcache updateA bcache updatePosted May 15, 2012 7:56 UTC (Tue) by Tobu (subscriber, #24111)In reply to: A bcache update by russell Parent article: A bcache update I think the SSD will be a single point of failure in writeback mode, because the underlying filesystem would have megabytes of metadata or journal blocks not written in the right order, which is bad corruption. I don't know how SSDs tend to fail; if they fail into a read-only the writes would still be recoverable in this case, as long as bcache can replay from a read-only SSD. Maybe a filesystem that handles SSD caching itself could avoid that risk.

Did you see my other comment ?
About how bcache will support more than one SSD in the future and how it will save 2 copies of your precious data on different SSDs instead of one:
