Product description

• Synology DiskStation DS718+ 2-Bay NAS Enclosure Built with a quad-core processor, an AES-NI hardware encryption engine, Btrfs file system support, and real-time 1080p/Cinema 4K video transcoding, the DiskStation DS718+ 2-Bay NAS Enclosure from Synology is designed for those who need a high-performance NAS that has been optimized for not only intensive workloads, centralizing data backups, and storing UHD media content, but also to safeguard data and deliver fast file transfer speeds It is equipped with two drive bays that are capable of natively supporting 3.5" SATA hard drives, as well as 2.5" SATA hard drives and SSDs. Using its two drive bays, this NAS will allow you to store and share many files, including videos, music, photos, and documents with up to 2048 user accounts and 500 maximum concurrent connections.
  
  The DS718+ runs on Synology DiskStation Manager (DSM) OS, which is a browser-based operating system which helps to simplify managing your Synology NAS. Its CPU is a 1.5 GHz Intel Celeron J3455 Quad-Core with a burst frequency of up to 2.3 GHz, and its 2GB of DDR3L RAM, which be upgraded to 6GB, allows frequently-used files and applications to be quickly accessed. The NAS can achieve encrypted read speeds of up to 226 MB/s and encrypted write speeds of up to 184 MB/s, while a dedicated hardware transcoding engine can transcode two-channel H.264 (AVC), H.265 (HEVC), MPEG-2, and VC-1 video at resolutions up to 4096 x 2160 at up to 30 fps via Video Station and DS video. This allows 4K videos to be converted and played on-the-fly on devices that do not natively support Ultra HD formats.
  
  Also featured are three USB 3.0 Type-A ports and eSATA port which allow it to be connected to your Windows or Mac system, and network connectivity is achieved via the dual Gigabit Ethernet ports that support Link Aggregation and Failover, allowing your stored data to be shared with users throughout the network. Data may also be made remotely available through the free iOS and Android applications. For those who require RAID support, the DS718+ supports RAID 0 and 1, as well Synology Hybrid RAID and Basic RAID, each of which offers performance, data redundancy, or a combination of both. For those who do not require a RAID, JBOD is also available, allowing each drive bay to be individually utilized. Additionally, once connected to a DX517 expansion unit, RAID 5, 6, and 10 are also supported.
  
  The DS718+ is engineered to be energy efficient. Not only does it offer a 92 x 92mm fan to help keep the system running cool at all times, its noise dampening design of 18.4 dB(A) makes for quiet operations. The server supports numerous scheduled power on/off cycles and hard drive hibernation to further minimize power consumption and operation expenses.
  
  The Synology DiskStation DS718+ 2-Bay NAS Enclosure operates on 100-240 VAC at 50/60 Hz and includes an accessory pack, a 65W AC power adapter, a power cord, and two RJ45 LAN cables. It is protected by a limited 3-year warranty.

• 2 x WD 6TB Red 5400 rpm SATA III 3.5" Internal NAS HDD (OEM) Designed with home and small office/business customers in mind, the 6TB Red 5400 rpm SATA III 3.5" Internal NAS HDD from WD is well-suited for NAS environments with up to eight 3.5" drive bays. Engineered to handle increased workloads, this 6TB drive operates using a SATA III 6 Gb/s interface, a 64MB cache, and a rotational speed of 5400 rpm, all of which help to ensure uninterrupted data transfers with a sustained rate of up to 175 MB/s. This drive also features high levels of reliability, with 600,000 load/unload cycles, <10 in 10¹⁴ non-recoverable read errors per bits read, error recovery controls, and 1,000,000 hours MTBF for 1-8 bay NAS systems. Also built into this drive are noise and vibration protection and WD's NASware 3.0 helps increase system compatibility, allowing WD Red drives to be more easily integrated with your existing network infrastructure.

  General Features

  Fill Your NAS with WD Red
  • Built for 1 to 8-bay NAS systems, WD Red lets users store their data in one unit
  NASware 3.0 Technology
  • Built into every WD Red hard drive, NASware 3.0's technology helps improves your system's storage performance by increasing compatibility, integration, upgradeability, and reliability
  Built for NAS Compatibility
  • Desktop drives aren't purpose-built for NAS, but WD Red drives with NASware are. WD's technology helps takes the guesswork out of selecting a drive. WD Red is for small NAS systems and WD's algorithm balances performance and reliability in NAS and RAID environments
  Desktop Drives vs. WD Red
  • Desktop hard drives are not designed for NAS environments. Do right by your NAS and choose a drive with an array of features to help preserve your data and maintain optimum performance. Take the following into consideration when choosing a hard drive for your NAS:
    
  • Compatibility: Without being tested for compatibility with your NAS system, improved performance is not guaranteed
  • Reliability: The always-on environment of a NAS or RAID is a hot one and desktop drives aren't typically tested in those conditions. WD Red is
  • Error Recovery Controls: WD Red NAS hard drives are specifically designed with RAID error recovery control to help reduce failures within the NAS system. Desktop drives are not typically designed for RAID environments where this can be an issue
  • Noise and Vibration Protection: Designed to operate solo, desktop drives offer little or no protection from the noise and vibration faced in a multi-drive system. WD Red drives are designed for multi-bay NAS systems
  WD Red for Home
  • Stream, backup, share, and organize your digital content at home with a NAS and WD Red drives designed to share content to the devices in your home. Red NASware helps increase your drives' compatibility with your devices, TV, stereo, and more
  WD Red for Small Business
  • WD Red is a good hard drive choice for 1 to 8 bay systems. NASware 3.0 allows for integration with your existing network so WD Red can share and backup files at the speed of your business. For larger businesses with up to 16 bays, use WD Red Pro
  3D Active Balance Plus
  • This helps ensure your data is protected from excessive vibration and noise in a NAS or RAID environment. This dual-plane balance control helps reduce the degradation of your drive over time
  Reliability
  • Since your NAS system is always on, a reliable drive is essential. With an MTBF of up to 1 million hours, the WD Red drive with NASware 3.0 is designed for 24x7 environments
  Cooler Operations
  • By reducing power consumption, the operating temperature of your NAS stays cooler. With a lower temperature in your system, you can create a more reliable solution for your NAS
