Built with a quad-core processor, an AES-NI hardware encryption engine, Btrfs file system support, and Cinema 4K video transcoding, the DiskStation DS918+ 4-Bay NAS Enclosure from Synology is a powerful and scalable system designed for growing small- and medium-sized businesses and IT enthusiasts. It provides fast encrypted and sequential file transfers and can transcode up to two channels of H.265/H.264 4K video simultaneously, and is well-suited for storing and sharing Ultra HD media content. It is equipped with four drive bays that are capable of natively supporting 3.5" SATA hard drives, as well as 2.5" SATA hard drives and SSDs for data storage, plus two M.2 2280 NVMe SSD slots for caching. Using its four drive bays, this NAS will allow you to store and share a large number of files, including videos, music, photos, and documents with up to 2048 user accounts and 1000 maximum concurrent connections.
The DS918+ 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 4GB of 1866 MHz DDR3L RAM, which be upgraded to 8GB, allows frequently-used files and applications to be quickly accessed. The NAS is capable of achieving encrypted sequential read speeds of up to 225 MB/s and encrypted sequential write speeds of up to 221 MB/s, while a dedicated hardware transcoding engine can simultaneously transcode two channels of 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 two 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 DS918+ supports RAID 0, 1, 5, 6, and 10, 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.
The DS918+ is engineered to be energy efficient. Not only does it offer two 92 x 92mm fans to help keep the system running cool at all times, its noise dampening design of 19.8 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 DS918+ 4-Bay NAS Enclosure operates on 100-240 VAC at 50/60 Hz and includes an accessory pack, a 100W AC power adapter, a power cord, and two RJ45 LAN cables. If you need to expand its storage, the DS918+ can be connected to one DX517 expansion unit. Protection is provided by a limited 3-year warranty.
