    Update :
    Samsung's F2FS (Flash Friendly File System) has gained major performance improvement & bug fixes for upcoming Linux Kernel 3.12

    On side note : You should use F2FS for RPi or any ARM based mini-computer like Beaglebone,UDOO,etc. It not only increases the life of SDHC but it's also faster than Ext4.
