Would it be a good idea to use BTRFS on a flash-based memory device ? BTRFS is a log-structured filesystem, just like ZFS. Log-structured filesystems try to write all data in one long log without overwriting older data, which is ideal for flash-based devices. And these filesystems typically use a block size of 64 KB or more. See also: * http://oss.oracle.com/projects/btrfs/ * http://www.cs.berkeley.edu/~brewer/cs262/LFS.pdf
