[mdlug] Best File System for 1TB Raid5

[Joe St.Clair]

I have a Promise SmartStor NS4300N.  It has (4) 500gb SATA drives in 
it.  The box runs "Busybox" Linux,
has a Fasttrak PCI RAID controller, uses EXT3 file system and is being 
used by several work
stations.  I mount the network drive via Samba and NFS.  I have the 
drive about 30% full and have not
had any data problems.  I use the box primarily for large CAD files.  
The box has been running for over 1
year and the only time it has been off is during a power failure.  The 
box is connected to a APC UPS and
will perform automatic shutdown in the case of a power failure.  I also 
have (2) Linux boxes running XFS
file systems.  If I had my choice I would have use XFS but it was not a 
choice on the Promise box.
