Nevertheless, writing (essentially) append-only files is something that happens often enough that most filesystems should cope with reasonably well. And writing 20x slower than it could is nowhere near coping reasonably well.<p>(Also: note that you don&#x27;t need to cope with nfs&#x2F;etc. Flash is different enough from spinning rust that I have no problem with a filesystem being optimized for one or the other as opposed to both.)
