The choice of OS, Volume Manager, and a file system - all depends on your level of comfort with each.I concur with @BoredSysadmin stay away from SATA hubs/ replicators, get a proper HBA for your disks, there's little point in storing up trouble for yourself further down the road. I would go as far as to say, roll your own storage on Linux, rather than going the Freenas route, unless you can use ECC memory with a different CPU/ config, I wouldn't recommend using ZFS, stick with traditional mdraid etc
