QNAP TS-873 Diskless 8-bay NAS/iSCSI IP-SAN AMD RX-421ND 2.1~3.4 GHz, 4GB DDR4 RAM, 4x 2.5"/3.5" + 2x M.2 2280/2260 SATA 6Gb/s drives, 4x GbE LAN, optional 10GbE PCIe expansion.
The TS-873 is powered by a high-performance and energy-efficient AMD R-Series CPU and provides two PCIe slots for greater functionality. You can install a QNAP QM2 expansion card to add M.2 SSD caching/10GbE connectivity; a compatible wireless card to use the TS-873 as a wireless access point; and an entry-level graphics card to boost system performance for 4K video performance. The TS-873 allows you to flexibly deploy a wide range of applications with a more affordable budget.
|Two PCIe Gen3 x4 slots support QM2 cards, 10GbE adapters, or wireless network cards.||Supports entry-level graphics card, allowing for 4K video transcoding and output.||Dual M.2 SATA 6 Gb/s SSD slots allow for setting up caching or storage pools, improving file access efficiency.|
|Qtier™ auto-tiering technology and SSD caching enable 24/7 optimized storage efficiency.||Scalable storage supporting virtualization, containerized apps, centralized storage, backup, sharing, and disaster recovery.||Snapshots fully record system status and data. If files are accidentally deleted or modified, you can quickly restore the data from a snapshot.|

Configured system orders start here!
The selected drives are batch controlled and tested using our HDD and SSD servers. Passed drives are then installed in the NAS with Volume and RAID set. Our pre-burn testing prepares the NAS with an initial system and drive testing cycle to ensure that the integrity of the entire system is tested and passed with no issues at all.
Our stress testing (burn-test) cycle commences for a minimum of 24 hours and extends to 48 hours if requested or required. This is undertaken in order to ensure stability when used in a normal environment. These tests can include extremes of workload (constant I/O's), CPU and memory use, thermal load (heat), clock speed, or voltages, bus and connectivity components, with the primary stress testing software aiming to test stability by trying to force a system to fail. Our tests put a greater emphasis on robustness, availability and error handling heavy loads.
Once the tests are complete we QA and pack the system back into it's retail box. Then it's double boxed to protect the unit during shipping. You receive your QNAP NAS Ready To Plug 'N' Store. It doesn't get any easier. Buy your NAS from the QNAP EXPERTS at QNAP DIRECT.
