You *COULD* do this, but keep in mind desktop class hardware may give you poorer performance, especially for fileserver use. You seem to have the storage requirements down, but make no mention of performance requirements. They are moving huge files to/from the server, but are they expecting it to happen in a few minutes or take all day? You mention 50 machines, but how many *CONCURRENT* connections? The more concurrent sessions you have, the poorer it may perform due to disk thrashing. A *GOOD* storage controller added to a desktop class machine on a PCIe bus will do wonders for you.

For mirroring, you'll want RAID-1. This automatically keeps both drives/partitions in sync as the data is transferred, no need for rsync or any external scripting other than checking the health of your array(s).

I'd suggest something more 'yum' like than 'apt'.

 A poor attempt at package manager humor. RHEL/CentOS 'yum' vs Debian/Ubuntu 'apt'. :-)
