Synology DS1019+ vs. DS918+: Which NAS should you buy?

The DS1019+ and DS918+ are similar NAS servers from Synology, with only a few minor spec changes to differentiate the two and warrant the increase in price for the DS1019+. Should you be after a solid four-bay NAS for your home or small office, the DS918+ is a great server, while the DS1019+ lets you install a further hard drive for additional storage.

Synology DS1019+ vs. DS918+ specs

The DS1019+ is essentially the DS918+ but stretched slightly to accommodate a fifth drive bay. All the internals are the same, aside from 8GB of RAM being pre-installed. You get the same Intel Celeron processor, an identical number of M.2 slots for speedier cache, and the same external port configuration.

Other notable differences are dimensions, weight and power consumption — the DS1019+ uses around 10W more power with the additional drive and RAM. This extra drive bay does allow for 14TB more space to be available, bringing the total up to 70TB and 140TB when using Synology's expansion unit.

Everything else is the same

Taking the extra capacity and RAM aside, everything else with the DS1019+ is exactly the same as the DS918+. The same excellent DSM OS is installed with access to a whole host of third-party software, including Plex. The two NAS even share the same NAS design with the former being slightly larger to include the additional bay.

Because the two NAS servers are very similar in design, specs and everything else, it makes the considerable jump in price a little more difficult to justify. If you truly require five hard drives to be installed on your NAS, paying out an extra $100 for the luxury may seem like a bad deal.

It's possible to go with the DS918+ and use Synology's five-bay expansion unit to bring the total number of bays up to nine, but the expansion unit alone will set you back $500.

DS1019+ is for you if you need extra capacity

The main separation between the DS1019+ and DS918+ is the addition of the extra drive bay and more pre-installed RAM. Really, out-the-box it's the better NAS, but you're paying a fair amount more for this privilege.

Go with the DS918+ to save a little

If you know you won't require five drive bays and 8GB RAM, you can save a little and grab the DS918+, which comes with four drive bays (more than enough for most home installations) and everything you need to set up your own home server.
