Ext4 is freaking awesome.  One of the major features found in ext4 is
extents.  Basically, setting aside a contiguous area of disk space for a
file.  This will seriously reduce file fragmentation, and increase disk
space efficiency.

Further, ext4 is both backwards compatible (mounting an ext3 filesystem
as ext4), and forwards compatible (an ext4 filesystem can be mounted as
ext3) with ext3.  Other features of ext4 include nanosecond timestamps,
online defragmentation, journal checksums and the ability to address 1
exbibyte of storage.

Count me in for ext4.
