QNAP TS-1655 16-Bay Tower NAS

Room for Capacity and a Faster Storage Tier The QNAP TS-1655 brings twelve HDD-sized bays and four dedicated SATA SSD bays into one business tower. An eight-core Intel Atom processor, dual 2.5GbE and three PCIe slots give shared files, backup repositories and carefully sized applications a flexible foundation, while two internal M.2 slots provide another SSD option. Highlights Hybrid Storage by Design Twelve 3.5-inch SATA HDD/SSD bays plus four 2.5-inch SATA SSD bays Two M.2 2280 PCIe Gen 3 x2 slots for supported SSDs Build Around the Network Two built-in 2.5GbE ports Three PCIe Gen 3 x4 slots for verified network or storage adapters Business Data Services Eight-core Intel Atom C5125 processor QTS or QuTS hero storage, snapshots and backup applications Key Features Give HDDs and SSDs Distinct Jobs Use the larger SATA bays for a capacity-oriented drive group and the dedicated SSD bays for an appropriate system, application or performance role. The internal M.2 slots provide a separate NVMe path. Select compatible drives and match the storage layout to the operating system instead of assuming that every drive position accepts every interface. Expand the Network When the Workload Calls for It Dual 2.5GbE provides the starting network connection. Supported optional PCIe adapters can add faster Ethernet, Fibre Channel or other approved interfaces. Three slots provide flexibility, but card dimensions, cooling and adjacent-slot clearance still matter. Quoted interface speeds are link rates rather than promised file-transfer performance. Choose the Storage Operating System Deliberately QTS provides an EXT4 environment, while QuTS hero uses ZFS with supported integrity, compression and data-protection functions. Choose the OS and memory configuration before deployment. Moving between them requires reinitialisation and a prior backup; existing drive pools are not simply transferred between filesystems. Build Recovery Into Everyday Work Use snapshots for supported recovery points, Hybrid Backup Sync for another destination and Qsync for file synchronisation. These tools serve different purposes. RAID provides configured drive redundancy, but an independent, current backup remains necessary for important data and should be tested before it is needed. Plan Expansion as a Complete Connection Compatible USB, SATA JBOD and SAS enclosures provide different expansion routes. The enclosure alone is not the full configuration: host controllers, correct cables, firmware and OS support must also match. The USB4 route needs an optional compatible USB4 card; the onboard USB ports are not USB4. Size Applications Alongside Storage Virtualization Station and Container Station can consolidate compatible workloads, subject to available CPU, memory and storage resources. Camera recording should be planned separately from playback and AI analytics. Reserve resources for NAS services and use the stated recording assumptions when comparing surveillance configurations. Summary Choose the TS-1655 for a tower deployment that needs a clear HDD/SSD split, flexible adapter choices and substantial internal drive space. Plan the drive groups, memory and network together, then add verified expansion hardware as the workload grows. Frequently Asked Questions Are Drives Included?ExpandCollapse No. This is a diskless NAS. 12 × 3.5-inch SATA HDD/2.5-inch SATA SSD bays plus 4 × 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 2 × 2.5GbE RJ45, supporting 2.5G/1G/100M/10M; faster Ethernet requires a supported optional PCIe adapter. 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: 105 channels. This uses 12 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. 続きを読む
