Synology DDR4 RAM has been available in the market for a few years now and it is mainly targeted at businesses.

But with the release of the Synology DiskStation DS20 Plus series for consumers, you can finally get the DDR4 RAM to go along with your new shiny DS920+, DS720+, DS420+, or DS220+.

Previously, I got the Synology DDR3 RAM for my Synology DiskStation DS918+ and now I got it for my Synology DiskStation DS920+.

DS920+ comes with 4GB of RAM, and you can expand it to 8GB (4GB + 4GB) whereas DS720+, DS420+, and DS220+ comes with 2GB of RAM and is expandable to 6GB (2GB + 4GB).

With more RAM, your NAS will have a better performance, which in turn gives you better multitasking capability when using DiskStation Manager (DSM). For the unaware, DSM is the web-based operating system for your Synology NAS.

If you are using Virtual Machine on DSM, with the extra RAM, you can either allocate more RAM to the virtual machines so that they perform better or spin up more Virtual Machines.

If you are using Docker on DSM, you can run more containers with more RAM.

There are five types of Synology DDR4 RAM available:

  • Non-ECC SO-DIMM: D4NESO-2666-4G (4GB)
  • ECC SO-DIMM: D4ECSO-2666-16G (16GB)
  • Non-ECC UDIMM: D4NE-2666-4G (4GB)
  • ECC UDIMM: D4EC-2666-8G (8GB), D4EC-2666-16G (16GB)
  • ECC RDIMM: D4RD-2666-16G (16GB), D4RD-2666-32G (32GB)

For the general consumers, you just need to get the Non-ECC SO-DIMM, and the modal number is D4NESO-2666-4G. It only comes in 4GB.

The Synology D4NESO-2666-4G retails for S$139, and I recommend you to get it especially you are an owner of any NAS from the DS20 Plus series.

Technically, you do not need to get the Synology branded RAM from Synology. However, if things go wrong when you are installing a third-party RAM into your NAS, your warranty will be voided.

Also, you need to Google and do some research on which third-party RAM is suitable for your NAS. Why not just pay a little bit more for a piece of mind and time saved?
