The TS-473 features two PCIe (Gen3 x4) slots, allowing for installing single/dual-port 10GbE NICs to accelerate applications that demand higher bandwidth such as virtualization, media workflows, and backup/restoration tasks for an ever-growing amount of data; or a USB 3.1 Gen2 (10Gb/s) expansion card for transferring large media files to and from USB storage. You can also install QM2 cards, wireless network cards or an entry-level graphics card to extend NAS functionality.
SSD caching and 10GbE connectivity
The TS-473 supports the innovative QM2 PCIe card that allows for adding up to two M.2 SSDs. You can configure SSD caching, or create a RAID 5 tiered storage along with the two M.2 SSDs in the NAS. As these M.2 SSDs will not occupy any 3.5-inch drive bays, the QM2 card allows you to maximize both your storage capacity and performance. There are also QM2 cards that include 10GbE 10GBASE-T connectivity to provide SSD caching with high-speed network connectivity on a single card.
Optimal computing power and 4K video playback with a graphics card
The TS-473 allows for installing a low-power graphics card (powered solely by the PCIe slot) to boost system performance. With a graphics card installed, the TS-473 also enables smoother video editing workflows and supports 4K UHD transcoding to deliver an exceptional multimedia experience.
Optimized collaboration with seamless file sharing and sync
The TS-473 centrally stores data and various files, and supports SMB/CIFS, AFP and NFS protocols for file sharing across Windows, Mac, Linux/UNIX networks. Coupled with Qsync - a utility that turns a QNAP NAS into a safe, high-capacity data center for file synchronization - any file uploaded to the TS-473 will be made available for all linked devices, such as computers, laptops and mobile devices. You can sync shared folders and team folders for group file sharing, greatly enhancing the flexibility of team projects and collaboration. Files can be centrally managed using File Station, including files from mobile devices and optical disc drives. File Station also allows you to mount a remote NAS, and transfer files between your NAS and public cloud services for greater convenience.
