Both systems are desktop NAS appliances aimed at home, home office and small to medium business users. Inside each box is a 1.2GHz CPU and 512MB DDR2 RAM which powers an embedded operating system. The box includes front and rear-facing USB 2.0 ports, an external Serial ATA (eSATA) interface for hooking up additional devices, and a Gigabit Ethernet (GigE) network interface.
The software that runs the TS-119 and TS-219 enables users to share files across a network. It supports Universal Plug and Play (UPnP) and DLNA to operate as a media server for digital music, photos and images. They also run "Turbo NAS" firmware 3.0, which provides an AJAX-based Web management interface that QNAP likens to Apple's Cover Flow feature in Leopard.
With Internet SCSI (iSCSI) target service support, the devices can also be part of a backup or storage expansion system; users can create up to eight "virtual" drives on the NAS for their existing servers or computers; iSCSI drives on the NAS can be formatted with a file system and used as local drives.
The TS-119 supports up to a 2 terabyte (TB) hard drive, and the two-bay TS-219 can support two hot-swappable drives for up to 4TB of capacity.
