I say HOGWASH to Michael Mansour. SGI's XFS is know for BOTH SPEED AND RELIABILITY! I would not use any other file system, no matter what the file/partition size, except XFS. I demand dependability and reliability of the file system and I get that and more from XFS. XFS has been around a lot longer than ext3 and is a mature and reliable file system with over a decade of testing and extended use from desktop machines to massive file servers. If you want dependability, reliability, and speed, go with XFS. I've had removable media corrupted by a hardware failure on one MO drive and on a working drive I was able to salvage all the information. XFS managed to recover everything. I thought for sure I was going to loose all the information, but I didn't.
