Specifications, Availability and Pricing
The QNAP TS-859U-RP uses a dual core Intel Atom processor and pairs it with 1GB of DDR2 RAM. The system is designed to use up to eight internal HDDs in RAID 0, 1, 5 or 6. Two additional eSATA ports are located on the back of the NAS and can be used to increase storage capacity.
The TS-859U-RP is an enterprise class system and as such brings many enterprise features with it. Redundant power supplies are one item that we never see on consumer models and most consumers don't use rackmount systems in their homes or small offices.
Dual gigabit Ethernet ports on the back of the QNAP TS-859U-RP allow data to flow quickly to and from the NAS and as long as your network is setup for it, setting up and using the fail over system is easy.
When it comes to the cost, the TS-859U-RP comes with an enterprise tag as well. Newegg currently lists the unit for just over 1900 USD. The upgrade TS-809U-RP is also available at just under 2200 USD.
