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.
High-speed 2.5GbE accelerates intensive file access, large backup/restoration tasks, virtualization, and multimedia transfer.
Two M.2 NVMe PCIe Gen 3 slots allow implementing SSD cache acceleration, SSD storage pool, or a Coral M.2 accelerator for faster image recognition.
Three PCIe slots allow for installing 5/10/25GbE adapters, Fibre Channel cards, or QM2 cards to increase application performance.
Host virtual machines and containerized apps on one device to optimize resource utilization and IT budgeting. Supports SR-IOV.
Realize hybrid cloud applications by working with the cache space reserved on NAS to ensure low-latency cloud data access.
Satisfy ever-growing storage needs by connecting flexible and economical QNAP expansion enclosures.
The TS-1655 adopts the Intel® Atom® C5125 8-core 2.8 GHz processor that supports Intel® QuickAssist Technology (QAT), offloading computationally-intensive compression and improving IPsec/SSL cryptography performance. The TS-1655 comes with four UDIMM DDR4 slots (8 GB preinstalled) that can be upgraded to 128 GB for higher workloads. Error-Correcting Code memory is also supported to deliver server-grade performance and reliability for rugged enterprise IT environments as a cost-efficient NAS solution.

Common Fibre Channel Storage Area Networks (SAN) devices are often costly. By installing QNAP dual-port 16Gb Fibre Channel expansion cards in the TS-1655, you have more budget-friendly options to add a NAS to a SAN environment. You can set a Fibre Channel Target using the iSCSI & Fibre Channel app. Moreover, the LUN Masking and Port Binding features provide an additional layer of data security.
QNAP provides easy ways to expand your storage capacity. Here are several ways to expand your TS-1655 storage as needed to accommodate data and business growth.
