The TS-853BU 8-Bay NAS Enclosure from QNAP is a 2 RU rackmount NAS that fits in 19" racks, providing a storage solution in server rooms for small and medium businesses. It is equipped with a PCIe Gen 2.0 x2 slot that can accommodate a QNAP QM2 expansion card for adding an M.2 SSD cache/10GbE Ethernet card, a Wi-Fi card to create a wireless access point, or a 10 Gb/s USB 3.1 card for helping to simplify backups to/from multiple external sources. Also provided is 4K video playback and real-time transcoding, deployment of virtual environments through Virtualization Station and Container Station, centralized management of remote Windows, Linux, and IPMI-compatible devices with QRM+, and web automation services with IFTTT Agent.
The TS-853BU is powered by a 1.5 GHz Intel Celeron J3455 Quad-Core processor, which will allow you to run multiple applications simultaneously and features a max boost speed of up to 2.3 GHz. The 4GB of DDR3L RAM has a configuration of 2 x 2GB and will allow quick access to frequently used files and programs. Network connectivity is achieved using the four Gigabit Ethernet ports which support failover, multi-IP settings, and port trunking/NIC teaming. There is also support for JBOD, single disk, and a variety of RAID modes, including RAID 0, 1, 5, 6, and 10, and 5/6/10+hot spare, each of which offers data redundancy, speed, or a combination of both.
This 8-bay enclosure has the ability to natively house both 3.5" and 2.5" SATA III hard drives or SSD drives, and screws are included that accommodate each drive size. With all four Gigabit Ethernet ports in use, the TS-853BU can deliver sequential read speeds of up to 405 MB/s and sequential write speeds of up to 431 MB/s. When using all four Gigabit Ethernet ports with volume encryption, which helps to prevent sensitive business data from unauthorized access and breaches, read speeds top out at 408 MB/s and write speeds reach 333 MB/s. Using the four external USB 3.0 Type-A ports, this QNAP NAS can be connected to other devices, such as QNAP expansion units.
QNAP's TS-853BU 8-Bay NAS Enclosure operates using a 250W ATX power supply. Included are two Ethernet cables, a power cord, 3.5" HDD flat head screws, and 2.5" HDD flat head screws. Protection is provided by a limited 2-year warranty.
