    1. several filesystems show performance improvements including XFS and Btrfs

      Now using btrfs on my notebook. Works fine!

      One of the reasons for using it (from btrfs.wiki.kernel.org):

      "SSD (Flash storage) awareness (TRIM/Discard for reporting free blocks for reuse) and optimizations (e.g. avoiding unnecessary seek optimizations, sending writes in clusters, even if they are from unrelated files. This results in larger write operations and faster write throughput)"

      Since btrfs once ate my data (pre 1.0) I did several crash simulations to boost my confidence beforehand.
