Google, which knows a thing or two about fast systems has decided, for their purposes anyway, that Ext4 is the best and close to the fastest file system of all.

Google’s Michael Rubin, a senior staff engineer, wrote, “Google is currently in the middle of upgrading from ext2 to a more up to date file system. We ended up choosing ext4.”

Rubin then explains, “The driving performance reason to upgrade is that while ext2 had been ‘good enough’ for a very long time the metadata arrangement on a stale file system was leading to what we call “read inflation”. This is where we end up doing many seeks to read one block of data. In general latency from poor block allocation was causing performance hiccups.”
