Pros And Cons


From the many reviews, this device seems to satisfy every user’s needs and wants in a NAS.

It is fast to accommodate all personal files, including music, movies, and other related stuff. The power saving feature also does a lot good to save power that is just enough for household use. It also provides an efficient way to share these files with all the members of the family.

Though there is undoubtedly a broad range of NAS that people can choose from, this model separates itself as a NAS exclusively designed for home use.

You don’t have to get a NAS that packed a lot of features that you necessarily don’t need. This saves you a lot of power (and money).

Also, since it targets household, the price is lower compared to NAS that could also be used for businesses, e.g., DS218. So if you really just want a personal one, this is the way to go.

In case 2 disks are not enough for your, the 4 disk model DS420j is available as an option.



If you read the reviews about this model, it can be easily seen that one of the most essential reasons why it is a standard option for many people is its ease of use.

The installation and configuration is a snap to accomplish, which can be done by just following the comprehensive instructions that have been provided.

It is also common for its users to commend the data speed. This may not be the fastest within the product category, but it can precisely deliver what has been identified with the specifications. Users of such were no longer surprised with how it can meet their expectations when it comes to its functionality.

Other things that can be attributed as reasons for the high level of satisfaction of its users include its ability to control UPS, having a mobile app that offers flexibility regarding how it can be managed, having a download manager, and its affordable price tag.

The latter is perhaps one that separates it from many others. In spite of its price, many people have reported that they are in awe of how it functions.

In spite of the kind words that have been expressed by its users, it is undeniable that there were also some areas of dissatisfaction.

Just like many other products on the market, this is not perfect. For instance, there were some who did not like the long time that will be required on the part of the user when it comes to re-indexing files.

Some people notice that the system in Synology DiskStation DS218j 2-bay NAS server hard disk makes some noise if it is placed in a quite room like a bedroom. Using SSD drives will eliminate this problem.

Though, many people note that the noise is not loud or annoying that would bother you. This, however, does not affect in any way on the performance of the device.

So if you can live with a little sound, then getting this model is not a bad choice.

Should You Upgrade From Synology 216j To 218j?

After comparing the new Synology DS218j with the older model, I have discovered that it is not worth it to upgrade if you already have the DS216j.

DS216j And DS218j Differences

The DS218j storage device has few improvements. The most prominent difference is a bit faster CPU clocking 1.3GHz vs 1.0GHz of the 216j model.

The difference is small enough to make upgrading unreasonable.

Its high performance has been highly commended, which makes it easier to understand why it is popular.
