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.
Intel ® Atom® C5125 8-core processor, 2.8GHz, 8 GB UDIMM DDR4 (1 x 8 GB)
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.

|
RAID Group |
To ensure data security, system stability, and storage performance, the maximum number of drives for a single RAID group is now 16 (applicable to RAID 5, RAID 6, RAID TP, and subgroups of RAID 50 and RAID 60). Nevertheless, users can combine multiple RAID groups into a large storage pool that contains more than 16 drives, using RAID 50, RAID 60, or RAID 10 as the RAID configuration. This enhancement will only be applied to new RAID groups. All existing RAID groups and storage systems will not be affected. |
