The main benefits that ext4 has over ext3 are:
1- faster time stamping
2- faster file system checking
3- journaling checksums
4- extents (basically automatic space allocation to avoid fragmentation)

Answer / jaswanth.saladi
ext2 : It was only the default file sysyem upto 7.1 redhat
version
->less speed,secure and doesnt supports journaling
ext3 : this was from the 7.2 redhat version
->more speed,secure n supports journaling compared to ext2
Journaling : This is one of the default feature of ext3
which provides multipls functions like data avaliability
across improper shut downs,esay transmission between the
file systems and speed etc...
