12x HDD + 4x SSD hybrid storage
2x M.2 NVMe slots, 2x 2.5GbE, 3x PCIe slots
Long-term availability (Up to year 2030)
Balance performance and cost with hybrid storage. Designed for diversified business IT environments, the high-capacity TS-1655 has twelve 3.5-inch SATA drive bays (for HDDs) and four 2.5-inch SATA drive bays (for SSDs) with 2.5GbE high-speed connectivity. Fueled by an immense 8-core Intel Processor, the TS-1655 presents a secure, scalable, and complete business-ready storage solution for cross-team file sharing, collaboration, backup & disaster recovery, virtualization, and intensive data transmission. The TS-1655 will be available and supported by QNAP for an extended period (up to 2030), ideal for businesses requiring matching NAS models deployed in multiple locations.
-
Dual 2.5GbE connectivity
High-speed 2.5GbE accelerates intensive file access, large backup/restoration tasks, virtualization, and multimedia transfer.
-
SSD caching and AI acceleration
Two M.2 NVMe PCIe Gen 3 slots allow implementing SSD cache acceleration, SSD storage pool, or a for faster image recognition.
-
Flexible PCIe expansion
Three PCIe slots allow for installing 5/10/25GbE adapters, Fibre Channel cards, or QM2 cards to increase application performance.
-
Virtual machines and containers
Host virtual machines and containerized apps on one device to optimize resource utilization and IT budgeting. Supports SR-IOV.
-
Hybrid cloud
Realize hybrid cloud applications by working with the cache space reserved on NAS to ensure low-latency cloud data access.
-
Storage scalability
Satisfy ever-growing storage needs by connecting flexible and economical QNAP expansion enclosures.
