Pros: 4 Drive bays expandable up to 16 TB. Easy setup with software. Informative OLED display. Many different drive configurations (RAID 0, 1, 5 JBOD). Internal fan keeps drives cool, and fan is relatively quiet.
Cons: Print server is very unstable and becomes virtually useless because of the stability issues. Windows often has trouble detecting in Windows Networks w/o D-Link software. Depending on router can take enormous amounts of bandwidth when transferring.
