All that being said, I can’t say I really notice any significant difference. Ubuntu Linux performed about the same running on NTFS using Wubi.exe as it does booting natively in EXT4.

Linux systems use a number of file system types – such as Ext, Ext2, Ext3, Ext4, JFS, XFS, ZFS, XFS, ReiserFS and btrfs.

According to the newest benchmarks provided by Linux-focused web site Phoronix, the EXT4 filesystem for Linux has gained some improvements as far as data loss goes with the latest Linux kernel ...
