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.
