QNAP TS-669 Pro @ techPowerUp
 

QNAP's TS-669 Pro NAS boasts six drive bays, which lets you create RAID arrays of up to 24 TB. Thanks to its Atom dual-core processor and dual Gigabit Ethernet, the device was responsive throughout all our testing. If you need more than the included 1 GB RAM, the system can be easily upgraded to 3 GB.
