Ext3 has become one of the most popular Linux filesystems. However, with hard drives sneaking up on a terabyte, concerns exist that ext3 won’t be able to handle 21st-century storage requirements.

This new filesystem features support for storage up to for 1024 petabytes per volume. A petabyte is 250 (two to the fiftieth power) bytes. If that sounds insanely large, think again. Individual supercomputers such as Lawrence Livermore National Labs’s BlueGene/L already have over a petabyte of storage and several storage networks are reputed to have well over a dozen petabytes.
