    General Features

    5-Bay 3.5"/2.5" SATA Expansion
    Add five additional drive bays to your Synology DiskStation DS1817+ and DS1517+. Supporting 2.5" SATA hard drives and SSDs, as well as 3.5" SATA hard drives, the DX517 is a flexible solution supporting on-the-fly volume expansion or serving as a local backup destination.
    Online Volume Expansion
    Managed from DiskStation Manager on the host NAS, the additional bays in the DX517 are immediately ready to be used once connected. On-the-fly volume expansion helps ensure that storage and services on the host are not interrupted during volume expansion.
    Hot-Swappable Drive Tray Design
    The hot-swappable drive trays of DX517 allow drive installation and replacement without powering down the system. A screwless drive tray design also helps reduce the time needed for system setup.
    Dedicated Local Backup Solution
    Synology's DX517 can be used as a dedicated local backup solution for the Synology DiskStation DS1817+ or DS1517+. When created as a separate volume, the DX517 provides a great backup solution to its local hard disks in case of system failure.

  • 5 x WD 8TB Red 5400 rpm SATA III 3.5" Internal NAS HDD

    Designed with home and small office/business customers in mind, the 8TB 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 8TB drive operates using a SATA III 6 Gb/s interface, a 128MB cache, and a rotational speed of 5400 rpm, all of which help to ensure uninterrupted data transfers with a sustained rate of up to 178 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
