Expands NAS potential with dual PCIe slots
The TVS-873e features a pair of PCIe (Gen3 x4) slots, allowing for installing optional 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 insert QM2 cards or wireless network cards to extend NAS functionality.
Note: USB 3.1 performance may vary depending on hardware/software limitations and usage environment.
Greater efficiency with SSD caching and 10GbE connectivity
The TVS-873e 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.
*Note: M.2 SSDs for NAS and QM2 cards are sold separately.
SSD cache with Qtier™ optimization for around-the-clock acceleration
The TVS-873e features SSD caching, and also supports optional M.2 SATA 6Gb/s SSDs. Using an SSD cache boosts overall system performance, and is perfect for improving the overall workflow of random IOPS demanding applications such as virtualization. QNAP’s Qtier™ Technology empowers the TVS-873e with auto tiering that further helps continuously optimize storage efficiency across M.2 SSD, 2.5-inch SSD, and high-capacity SATA drives with around-the-clock acceleration. The new Qtier™ 2.0 features IO-awareness that empowers SSD-tiered storage with a cache-like reserved space to handle burst I/O in real time, greatly maximizing the advantages of SSD.
Note: M.2 SSD is optional. As M.2 SSD operations can easily generate excessive heat, it is recommended to install a heatsink (from QNAP or a third-party provider) on the M.2 SSD.
Easy installation and direct access to files with USB QuickAccess
With its innovative USB QuickAccess port, the TVS-873e eliminates the complications of first-time NAS installation and provides direct access to files stored on the TVS-873e - all without needing network connectivity. Simply use a compatible cable* to connect the TVS-873e to a PC or Mac device, and use Qfinder Pro** to configure it. It is just that easy. You can also assign access rights to users for different folders to prevent unauthorized access to important files.
*Users must purchase a USB 3.0 A – Micro B cable or a USB 2.0 A – Micro B cable separately.
**Qfinder Pro and USB QuickAccess support Windows 8.0 (and later) and Mac OS X 10.7 (and later). Other versions may require driver installation.
Superior 4K video transcoding and dual 4K HDMI output
The TVS-873e features AMD 3rd Gen GCN architecture with breakthrough GPU performance to support 4K H.264 video decoding and stunning 4K UHD display.
