Re: [PLUG] The filesystem question...

[Dayton Gray <dgray@omnio.com>]

This is an interesting topic and one I have been researching a lot 
lately. I just purchased a 3ware 9550SX and have a 4 500GB drive raid 5 
setup in a hot-swap enclosure. I did some initial benchmarking with both 
ext3 and XFS and the writes were significantly faster with XFS (nearly 
twice as fast). I ended up sticking with ext3 however due to the fact 
that it is well supported and stable. If this data weren't so important 
to me (or I had a reliable backup solution in place) I would definitely 
build it XFS for the fantastic write speed. Reads were faster with XFS 
as well, but not by a large margin. As raid 5 will house my multimedia 
files, it is more important that I have reliable reads as I will not be 
writing to the disk often. If you anticipate a lot of writes to disk, 
XFS would be well worth it.

If you do go with XFS, make certain that you have a good UPS in place as 
I've read that the file system can become corrupted upon power failure 
more easily than ext3. With laptops, this would obviously be less of a 
concern.
