Super fast Ext4 filesystem arrives in Ubuntu 9.04

Ext4, the next generation of Linux’s Ext3 filesystem, is now available in the latest Ubuntu 9.04 installer images. Ext4 was officially declared stable in version 2.6.28 of the Linux kernel, which was released last month.

Ext4 is designed to provide better performance and increase reliability. It also increases the maximum filesystem size to one exabyte and reduces the amount of time that is required to perform a fsck operation.
