Description
The QNAP TS-855X-8G stands as a powerhouse in the desktop NAS category, engineered to bridge the gap between standard storage and enterprise-grade performance. Driven by the Intel Atom C5125 8-core 2.8 GHz processor, this unit provides the computational overhead necessary for intensive multitasking and high-speed data throughput. Its hybrid storage design—comprising six 3.5-inch SATA bays for high-capacity HDDs and two 2.5-inch SATA bays for high-speed SSDs—allows users to implement tiered storage or SSD caching without sacrificing primary storage capacity. With a built-in 10GBASE-T port and two 2.5GbE ports, it is ready for modern high-bandwidth network environments right out of the box.
This product is for:
- Small to Medium Businesses (SMBs): Ideal for organizations requiring a centralized, secure backup repository for PCs, Macs, and SaaS data.
- Creative Professionals: Video editors and photographers can leverage the 10GbE bandwidth for direct 4K video editing and massive file transfers.
- IT Administrators: Perfect for those managing virtualized environments, as it supports SR-IOV and multiple virtual machines or containers.
- Data-Intensive Power Users: Users needing massive scalability can expand the unit up to 48 additional drives via TL-series expansion enclosures.
- Security-Conscious Enterprises: Organizations requiring data integrity benefit from the 128GB RAM capacity and ECC memory support to prevent data corruption.
Detailed specifications:
- CPU: Intel Atom C5125 8-core/8-thread processor, up to 2.8 GHz.
- Memory: 8 GB non-ECC UDIMM DDR4 (Expandable to 128 GB via 4x slots; supports ECC).
- Drive Bays: 6 x 3.5-inch SATA 6Gb/s + 2 x 2.5-inch SATA 6Gb/s.
- M.2 Slots: 2 x M.2 2280 PCIe Gen 3 x4 slots for NVMe SSDs.
- Networking: 1 x 10GBASE-T (10G/5G/2.5G/1G/100M) and 2 x 2.5GbE (2.5G/1G/100M).
- PCIe Expansion: 2 x PCIe Gen 3 x4 slots for 25GbE cards or QM2 expansion.
- Power: 250W internal PSU, 100-240V.
Operating the TS-855X-8G provides a seamless experience for managing complex data workflows. The inclusion of SMB Multichannel allows users to aggregate the dual 2.5GbE ports for up to 5Gbps speeds, while the dedicated 10GbE port handles the heaviest traffic loads. The dual M.2 PCIe Gen 3 slots are pivotal for performance, enabling SSD caching or QuTS hero system drives to significantly reduce latency. The system's flexibility is further enhanced by its dual-boot OS protection, ensuring high availability and reliability during firmware updates or system configuration changes.
Compared to standard 4-bay or 6-bay NAS units, the TS-855X-8G offers a superior hybrid architecture that separates bulk storage from high-speed cache bays. While many competitors require an additional PCIe card for 10GbE connectivity, the TS-855X-8G includes it natively, leaving its two PCIe Gen 3 slots free for further upgrades like Fibre Channel or 25GbE networking. Its 8-core processor significantly outperforms the quad-core chips found in entry-level business NAS models, making it far more capable of handling concurrent virtual machines and heavy encryption tasks via AES-NI.
Q&A:
- How much RAM can I add to the TS-855X-8G? The system supports up to 128 GB of DDR4 RAM across four U-DIMM slots, and it is compatible with ECC memory for enhanced data reliability.
- Can I use the M.2 slots for storage volumes? Yes, the dual M.2 PCIe Gen 3 x4 slots can be used for SSD caching, high-speed storage pools, or as a system drive for the QuTS hero operating system.
- Does this NAS support 10GbE networking? Yes, it features one built-in 10GBASE-T port that supports 10G, 5G, 2.5G, 1G, and 100M speeds.
- Is the TS-855X-8G compatible with expansion units? Yes, you can connect QNAP TL-R1620Sep-RP or TL-R1220Sep-RP expansion enclosures to add up to 48 additional hard drives.
- What is the benefit of the 6+2 bay design? This hybrid layout allows you to use six high-capacity HDDs for your main data while using two dedicated 2.5-inch SSDs for caching or high-speed tiering without occupying the larger 3.5-inch bays.
