Summary: The TS-659 Pro Turbo NAS device is built for those who need 12TB of storage capacity but aren't fussed too much about speed. There are much faster - and cheaper - alternatives. However, the TS-659 Pro Turbo has plenty of server features to suit both the home and small offices.
Pros: Comprehensive server functionality, eSATA, good write speeds
Cons: Slow read speeds and poor streaming performance, doesn't support HFS+ file systems
