QNAP TS-855X 8-Bay Tower NAS

Bring 10GbE to Everyday Business Storage The QNAP TS-855X combines six HDD-sized SATA bays and two dedicated SATA SSD positions with an eight-core Intel Atom processor. Built-in 10GbE, dual 2.5GbE and internal M.2 NVMe provide a useful starting point for shared files, backup and carefully sized virtualisation, without requiring a network upgrade card for the first 10GbE connection. Highlights Included High-Speed Networking One 10GBASE-T port plus two 2.5GbE ports Supported SMB Multichannel with appropriate clients and network setup Separate Capacity and SSD Roles Six larger SATA bays plus two dedicated SATA SSD bays Two M.2 2280 PCIe Gen 3 x4 slots A Flexible Business Tower Eight-core Intel Atom C5125 processor Expandable DDR4 memory and two PCIe Gen 3 x4 slots Key Features Connect 10GbE Without an Extra Card Use the integrated 10GBASE-T port for a suitable high-speed network path, while the two 2.5GbE ports provide additional connection options. Supported SMB Multichannel can use multiple suitable connections, but it depends on the clients and complete network design. Link speed does not establish the transfer rate of a particular workload. Give SSDs an Appropriate Role The six larger SATA bays accommodate compatible HDDs or SSDs, while two dedicated SATA SSD positions and two internal M.2 slots provide additional choices. NVMe can serve supported storage or cache roles. Check drive compatibility, cooling and the intended OS before selecting the SSD configuration; M.2 devices are not hot-swappable. Leave Room for Approved Upgrades Two PCIe Gen 3 x4 slots accept verified compatible expansion options such as network or storage controllers. The two slots have different card-size limits. An adapter choice consumes a slot and may affect other expansion plans, so match the whole configuration rather than adding cards independently. Choose QTS or QuTS Hero QTS provides an EXT4 storage environment. The alternative QuTS hero environment uses ZFS and supported integrity, compression and snapshot functions. Allow sufficient memory for storage features and applications, and back up before changing OS because reinitialisation is required. ECC is optional and must not be mixed with non-ECC memory. Make Backups Part of the Configuration Hybrid Backup Sync supports another NAS, suitable external storage and supported cloud destinations. Snapshots provide recovery points for supported storage objects, while Qsync serves file synchronisation. Keep a separate, current backup of important files and test recovery; drive redundancy alone does not cover every data-loss event. Expand With the Right Controller Compatible USB, SATA JBOD and SAS expansion enclosures offer different routes to additional drives. Each has its own controller, cable and supported enclosure-count requirements. Plan those components with the available slots and OS, and keep camera recording, virtual machines and other NAS services within the resources of the chosen configuration. Summary Choose the TS-855X when included 10GbE, a clear HDD/SSD layout and room for approved adapters suit a business tower installation. Build the network, drive groups and backup destinations as one design, then size applications and recording workloads against the actual memory and storage configuration. Frequently Asked Questions Are Drives Included?ExpandCollapse No. This is a diskless NAS. 6 × 3.5-inch SATA HDD/2.5-inch SATA SSD bays plus 2 × 2.5-inch SATA SSD bays; SATA 6Gb/s or 3Gb/s. Select the exact compatible drive, interface and firmware before ordering; usable capacity is lower after RAID and system overhead. Which Network Ports Are Included?ExpandCollapse 1 × 10GBASE-T RJ45, 10G/5G/2.5G/1G/100M; 2 × 2.5GbE RJ45, 2.5G/1G/100M/10M. Check the clients, switches and cabling as well as the NAS; interface speed is not a guaranteed file-transfer rate. Which Expansion Units Can I Use?ExpandCollapse up to 1 × TL-D800C, TL-R1200C-RP; up to 2 × TR-002, TR-004, TR-004U. SATA JBOD choices include up to 2 × TL-D400S; up to 2 × TL-D800S; up to 2 × TL-D1600S; up to 2 × TL-R400S; up to 2 × TL-R1200S-RP. Each needs its matching QXP host controller, cable and supported slot. Enclosure counts are per listed type, not additive when mixing units. Verify OS, firmware and storage-pool restrictions. How Many Cameras Can It Record?ExpandCollapse QNAP’s QVR Surveillance planning estimate on QTS is 8GB: 66 channels. This uses 6 main SATA drives in RAID 6; dedicated SSD positions excluded. 1080p, H.264, 30fps, 4.096Mb/s per camera; recording only, without playback or AI analytics. It is not a tested or guaranteed maximum. QVR Surveillance provides 2 included channels plus 6 after registration; compatible paid licences are required above 8. Expanded QuTS hero recording channels remain listed as developing and need separate confirmation. Can I Upgrade the Memory?ExpandCollapse 8GB non-ECC DDR4 UDIMM; 4 slots; optional supported ECC memory, not mixed with non-ECC. 128GB with 4 × 32GB supported modules. Check the exact QNAP-supported module and installation rules; changing memory does not guarantee an application performance level. Does RAID Replace a Backup?ExpandCollapse No. RAID can provide configured drive redundancy, but it does not prevent every deletion, ransomware event, theft or enclosure failure. Keep an independent, current backup and test that important files can be restored. Magbasa pa
