The 4-bay TS-451D2 provides high storage potential for home and small business users to store, share, and back up files. Business users can leverage its dual-core Intel processor to enable seamless multi-user on-premises/remote access to work files, while home users can enjoy a high-quality multimedia experience with both streaming and direct 4K HDMI 2.0 output. Cloud Storage Gateways allow you to leverage your existing cloud storage to deploy a hybrid-cloud solution, while a built-in App Center provides a wide range of applications to add additional functionality to the TS-451D2.
Dual-core 2.0 GHz (burst up to 2.9 GHz) with AES-NI encryption acceleration
The TS-451D2 is powered by an Intel® Celeron® J4025 dual-core 2.0 GHz processor (burst up to 2.9 GHz), supports up to 8 GB DDR4 memory, and is compatible with SATA 6 Gb/s drives. With Intel® AES-NI encryption, the TS-451D2 secures data without impacting performance. The TS-451D2 also features four USB 3.2 Gen1 ports (including one USB one-touch copy button) and two Gigabit Ethernet ports for greater connectivity to help streamline your workflows.
Multi-point file backup, access, and sync
The TS-451D2 centrally stores data and files, and supports common file sharing protocols, including SMB/CIFS, AFP and NFS for Windows®, Mac®, and Linux®/UNIX® devices. Coupled with Qsync (a utility that transforms a QNAP NAS into a secure, high-capacity data center for file synchronization), any file uploaded to the TS-451D2 becomes available for all connected devices (such as computers, laptops, and mobile devices). Hybrid Backup Sync helps you easily backup or synchronize data on the TS-451D2 to another QNAP NAS, remote servers, or cloud storage for disaster recovery. Additionally, QuDedup technology greatly improves the efficiency of multi-version backup to the destination storage, while optimizing storage utilization. You can install the QuDedup Extract Tool on your computer and restore deduplicated files to their normal status.
Seamless integration with cloud data
The TS-451D2 can be easily integrated with mainstream cloud services. By deploying cloud storage gateways and enabling local caching on the TS-451D2, you can seamlessly use the cloud for storage, backup, and data recovery with low-latency access, providing an innovative hybrid cloud experience.
Directly host virtual machines and containers
Virtualization Station and Container Station provide comprehensive virtualization support, and the Network & Virtual Switch allows you to allocate physical network resources to virtual machines, containers, and the NAS to simplify network deployment.
Easy and secure remote connection with myQNAPcloud
myQNAPcloud allows you to remain connected to your TS-451D2 using a unique domain name. No complex routing or configuration is required, and myQNAPcloud strengthens SSL Certificate keys to 2048-bits to enable secure remote access, management, and sharing files and services on your TS-451D2.
Safeguard your environment with QVR Pro
QVR Pro is a modern NAS-based surveillance solution that simplifies camera management, storage space allocation, camera live view, and playback. Dedicated storage space for surveillance data can be configured on the TS-451D2 to optimize system performance, and surveillance feeds can be monitored at any time using the QVR Pro Client mobile app. Budget-constrained users can even use USB webcams as network cameras by using QVR Pro with the QUSBCam2 app.
Flexible and economical storage expansion
QNAP provides several ways to expand the storage capacity of your TS-451D2 to accommodate data and business growth.
