Synology DS918+ vs. Synology DS916+: Which NAS should you buy?

We recommend the purchase of the DS918+, simply because it's the newer model that replaces the aging DS916+. Should you already own the Ds916+ and are perfectly happy with the performance, there's no reason to upgrade.

Battle of the specs

Since the DS918+ is essentially the successor to the DS916+, there aren't massive changes between the two models. What is clear to see is the newer processor, more efficient RAM and a few minor alterations.

DS918+ brings numerous improvements

Synology didn't mess around with the new DS918+, changing up the chassis to omit the removable front panel, opting for an easier hot-swap system with a lock and key. There's also enhanced ventilation throughout the device, aiding to reduce overall thermals in operation.

Speaking of heat, the DDR3L RAM replaces DDR3 modules previously installed, which match speed with less power required and heat produced. Simply put; the DS918+ should be a more efficient NAS, which is never a bad thing with a product that is expected to run 24/7.

Other than these improvements, not a whole lot has changed from the DS916+ to the DS918+, which is why we struggle to recommend forking out for the upgrade if you already own the older model, unless you have the available funds, frequently swap out drives, and desire a more efficient NAS.

However, if you're in the market for a new one and have to choose between the two, you should absolutely get the DS918+. It's not only improved in a lot of different areas, but it's also much easier to find. You can probably find a DS916+ on eBay, but that means possibly getting a used model, which means not taking advantage of a new version's power and longevity. If you want your NAS to last as long as possible, eBay isn't your best bet.

Synology DS918+ is the NAS for you

There's very little to deter you from purchasing the DS918+ in favor of the DS916+, aside from snatching a good deal. This newer model for 2018 has better internals, more efficient components, and a better overall design. It's future-proof and does everything you need a NAS to do.

It's okay to stick with the DS916+

Should you already own the DS916+, there's no reason to upgrade to the DS918+ unless you care about the small improvements made in the successor NAS.
