Comparison: Linux and UNIX ~ ZFS vs XFS vs EXT4 filesystem

Posted by Vivek Gite [Last updated: August 30, 2007]

This is an interesting filesystem comparison. If you are looking to build cheap storage for personal use file system decision is quite important:

This is my attempt to cut through the hype and uncertainty to find a storage subsystem that works. I compared XFS and EXT4 under Linux with ZFS under OpenSolaris. Aside from the different kernels and filesystems, I tested internal and external journal devices and software and hardware RAIDs. Software RAIDs are "raid-10 near2" with 6 disks on Linux. On Solaris the zpool is created with three mirrors of two disks each. Hardware RAIDs use the Areca's RAID-10 for both Linux and Solaris. Drive caches are disabled throughout, but the battery-backed cache on the controller is enabled when using hardware RAID.
