The 4-bay TS-451D2 provides high storage potential for home & small business users to store, share, & 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 & 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&174; Celeron&174; J4025 dual-core 2.0 GHz processor (burst up to 2.9 GHz), supports up to 8 GB DDR4 memory, & is compatible with SATA 6 Gb/s drives. With Intel&174; AES-NI encryption, the TS-451D2 secures data without impacting performance. The TS-451D2 also features four USB (Universal Serial Bus) 3.2 Gen 1 ports (including one USB (Universal Serial Bus) one-touch copy button) & two Gigabit Ethernet ports for greater connectivity to help streamline your workflows. Multi-point file backup, access, & sync The TS-451D2 centrally stores data & files, & supports common file sharing protocols, including SMB/CIFS, AFP & NFS for Windows&174;, Mac&174;, & Linux&174;/UNIX&174; 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, & 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. in addition, Qu Dedup technology greatly improves the efficiency of multi-version backup to the destination storage, while optimizing storage utilization. You can install the Qu Dedup Extract Tool on your computer & 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 & enabling local caching on the TS-451D2, you can seamlessly use the cloud for storage, backup, & data recovery with low-latency access, providing an innovative hybrid cloud experience. Directly host virtual machines & containers Virtualization Station & Container Station provide comprehensive virtualization support, & the Network & Virtual Switch means that you can allocate physical network resources to virtual machines, containers, & the NAS to simplify network deployment. Easy & secure remote connection with my QNAPcloud my QNAPcloud means that you can remain connected to your TS-451D2 using a unique domain name. No complex routing or configuration is required, & my QNAPcloud strengthens SSL Certificate keys to 2048-bits to enable secure remote access, management, & sharing files & 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, & playback. Dedicated storage space for surveillance data can be configured on the TS-451D2 to optimize system performance, & surveillance feeds can be monitored at any time using the QVR Pro Client mobile app. Budget-constrained users can even use USB (Universal Serial Bus) webcams as network cameras by using QVR Pro with the QUSBCam 2 app. Flexible & economical storage expansion QNAP provides several ways to expand the storage capacity of your TS-451D2 to accommodate data & business growth.\n\n\n\n Storage Total installed storage capacity 4 TBOnline RAID migration Yes Online RAID expansion Yes Storage drives installed Yes Installed storage drive type HDDSupported storage drive types HDD & SSDNumber of storage drives supported 4 Hot-swap drive bays Yes RAID support Yes Supported file systems FAT32, HFS+, NTFS, ext 3, ext 4RAID levels 0, 1, 5, 6, 10, JBODSupported storage drive interfaces Serial ATA II, Serial ATA IIIStorage drive sizes supported 2.5, 3.5"RAID rebuild Yes Processor Processor manufacturer Intel Processor threads 2 Processor cache 4 MBProcessor boost frequency 2.9 GHz On-board graphics adapter model Intel&174; UHD Graphics 600CPU configuration (max)1 Processor frequency 2 GHz Processor family Intel&174; Celeron&174; Processor model J4025 Processor cores 2 Memory Internal memory type DDR4 Internal memory 4 GBMaximum RAM supported 8 GBMemory slots 2 Flash memory 4000 MBMemory form factor SO-DIMMNetwork Ethernet LANYes Ethernet LAN data rates 10, 100, 1000 Mbit/s Wake-on-LAN ready Yes Jumbo frames support Yes DHCP server Yes DHCP client Yes Ports & interfaces USB port Yes USB 3.2 Gen 1 (3.1 Gen 1) Type-A ports quantity 4HDMI version 2.0HDMI ports quantity 1 Ethernet LAN (RJ-45) ports 2 Hard drive RAID support Yes Supported file systems FAT32, HFS+, NTFS, ext 3, ext 4RAID levels 0, 1, 5, 6, 10, JBODGraphics On-board graphics adapter model Intel&174; UHD Graphics 600 Design Cooling type Active Fan diameter 12 cm Cable lock slot type Kensington Product colour Black Number of fans 1 fan (s)LED indicators HDD, LAN, Power, Status, USBChassis type Desktop Cable lock slot Yes Technical details Type NASDevice class Home & Home Office Backup function Yes Backup features Cloud, USB (Universal Serial Bus) drive, i SCSI LUNProduct colour Black Noise level 18.5 d B Multilingual support Yes LED indicators HDD, LAN, Power, Status, USBChassis type Desktop Buzzer Yes Number of fans 1 fan (s) Performance S.M.A.R.T. support Yes Hot spare Yes Browser supported Apple Safari 7+, Google Chrome, Microsoft Internet Explorer 10+, Mozilla Firefox Type NASDevice class Home & Home Office Backup function Yes Backup features Cloud, USB (Universal Serial Bus) drive, i SCSI LUNOn/off switch Yes Windows operating systems supported Yes Server operating systems supported Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, Windows Server 2019 Mac operating systems supported Yes Linux operating systems supported Yes Security algorithms 256-bit AES, FIPS 140-2, SSH, SSL/TLSNoise level 18.5 d B Multilingual support Yes Buzzer Yes Third-party support Yes Cooling Cooling type Active Fan diameter 12 cm Number of fans 1 fan (s) Security Cable lock slot type Kensington Security algorithms 256-bit AES, FIPS 140-2, SSH, SSL/TLSCable lock slot Yes Software Windows operating systems supported Yes Server operating systems supported Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, Windows Server 2019 Mac operating systems supported Yes Linux operating systems supported Yes Management features On/off switch Yes Power Power supply location External Power supply unit (PSU) capacity 90 WAC input voltage 100
