Overview & Value Proposition
The QNAP TS-855X is a compact, high-performance 8-bay desktop NAS engineered for small-to-medium businesses and enterprise branch offices requiring versatile, hybrid storage capabilities. Powered by an 8-core Intel® Atom® processor, it delivers robust multi-threaded compute, native 10GbE and 2.5GbE networking, and dual M.2 NVMe SSD slots for performance acceleration. Supporting both the feature-rich QTS operating system and the ZFS-based QuTS hero system, the TS-855X provides flexible storage tiering, enterprise-grade data protection, and seamless virtualization host support in a quiet desktop footprint.
8-Bay Hybrid Storage Capacity: Houses up to 6 x 3.5"/2.5" SATA HDDs/SSDs alongside 2 dedicated 2.5" SATA SSD bays, optimizing hybrid storage tiering and drive configurations.
8-Core Intel® Atom® Processor: Powered by an Intel® Atom® C5125 8-core 2.8 GHz processor with Intel® QuickAssist Technology (QAT) to accelerate data encryption and compression tasks.
Dual M.2 PCIe NVMe SSD Slots: Integrated M.2 2280 PCIe Gen 3 slots enable high-speed SSD caching or fast storage pool creation without utilizing primary 3.5" drive bays.
High-Speed 10GbE & 2.5GbE Connectivity: Outfitted with one native 10GbE BASE-T port and two 2.5GbE RJ-45 ports to facilitate high-bandwidth file transfers, virtualization traffic, and multi-user access.
Scalable DDR4 ECC Memory: Supports up to 128GB of DDR4 memory with Error-Correcting Code (ECC) protection to ensure high operational stability and prevent system crashes during heavy workloads.
PCIe Gen 3 Expansion Slots: Features dual PCIe expansion slots to accommodate optional high-speed network cards, QM2 expansion cards, or SAS storage expansion adapters.
Flexible QTS / QuTS Hero Operating Systems: Allows IT managers to choose between the standard feature-packed QTS OS or the ZFS-based QuTS hero OS for advanced inline data deduplication, compression, and snapshot integrity.
Virtualization & Container Infrastructure Teams
For hosting virtual machines (VMware vSphere, Microsoft Hyper-V, Proxmox) and lightweight Docker containers with low-latency SSD storage options.
SMB IT & Enterprise Branch Offices
For centralized file sharing, automated multi-platform endpoint backups, and localized active directory integration in a quiet desktop form factor.
Creative Studios & Media Professionals
For collaborative 4K video editing, high-resolution media archiving, and fast file distribution across 10GbE network environments.
Disaster Recovery & Data Management Teams
For organizations seeking flexible hybrid backup workflows utilizing ZFS self-healing features, block-level snapshots, and remote cloud replication.
Q: Can the TS-855X switch between QTS and QuTS hero operating systems?
A: Yes. Users can choose to run either QTS or ZFS-based QuTS hero upon initial setup depending on whether they prioritize flexible storage features or ZFS-backed data reduction and integrity.
Q: What memory type does the TS-855X support and can it be expanded?
A: The TS-855X supports high-speed DDR4 memory (including ECC modules to guard against memory corruption) and features 4 UDIMM slots supporting expansion up to 128GB RAM.
Q: Does the TS-855X support PCIe expansion for higher network throughput?
A: Yes. The system includes two PCIe Gen 3 expansion slots, allowing users to add additional 10GbE or 25GbE network interface cards, M.2 SSD adapter cards, or expansion enclosure interfaces.
Q: How do the dedicated 2.5" SSD bays benefit system performance?
A: The two dedicated 2.5" SATA SSD bays allow users to build separate high-speed SSD volumes or dedicated caching tiers, reserving all six 3.5" drive bays for high-capacity SATA hard drives.
Q: Can I request a formal quotation for procurement?
A: Yes, we issue formal quotation documents with complete pricing, tax breakdowns, and payment terms for corporate or institutional procurement processes.
Q: Do you provide GST invoices?
A: Yes, we provide valid GST invoices for all orders. You can enter your GSTIN during checkout or provide it with your order details to claim input tax credit.
Q: Do you deliver across India?
A: Yes, we deliver to pincodes across all states and union territories in India through our logistics partners.
Q: Can I request availability and lead time before ordering?
A: Yes, you can contact us with your product requirements and quantity to confirm current stock availability and estimated delivery timelines before placing your order.
