Now shipping the eagerly awaited Synology DS918+, originally shown at Computex 2017. The DS918+ is the first 4-bay from Synology that looks and feels like a DS1517+ with one less bay. So for Synology fans this is a big plus as with hot-swappable bays, it’s always easy to interchange drives.

The successor to the DS916+, the DS918+ sports a new processor – Intel Quad-core J3455 with AES-NI – up to 2.3GHz, 4GB DDR3 – expandable to 8GB, and with a host of other extra’s which we shall cover shortly. This 4-bay is a serious statement from Synology and will happily compete with the likes of QNAP, Thecus and other NAS vendors to ensure they stay ahead of the storage demands needed for home and small businesses.

The last few years Synology has worked feverishly transitioning its DSM software a notch or two above the rest of its competitors. Synology has been and continues to be a powerful tactician within the NAS operating system, their latest version of the DSM has almost reach the crescendo of being able to stand on its own as an operating system for all generic NAS servers. Synology are not just good with the operating system, they are excellent.


Why move up from the DS916+?

The DS918+ supersedes the DS916+ that is the only comparison between the two models. The DS918+ has a total makeover both internally and externally. Internally, sporting a new processor the Intel Quad-core J3455 with AES-NI – up to 2.3GHz, and more memory 4GB DDR3 it's expandable to 8GB more than that is a tad waste.  And with the addition of the new m.2 NVMe SSD offering means all caching options open to aid and abate increasing performance using the CPU and Memory as a catalyst to increase IOPS.

In addition to caching, Storage Tiering becomes a viable option when integrating HDD and SSD combinations. Externally, the M.2 NVMe slots are located outside allowing a convenient slot in method without using any tools to avoid complications, nice touch!

Finally, the Synology 4-Bay has hot-swappable trays having yearned for these for years! They have finally been incorporated and because of this upgrade and other major changes, we are now comfortable in our belief that Synology is serious about the 4-bay market and has finally admitted the lifecycle of 4-Bay NAS servers is still alive and kicking.

    Does this thing support online array expansion? I would guess it does since it support hot swap but it’s not specifically stated anywhere. Want to know for sure.
