I have bought this memory module to increase the memory on a Synology DS420+ NAS device. It works perfectly without any issues and it is much cheaper than the offical upgrade. It was delivered very quickly and on time. Recommended to everyone.

I needed to upgrade my Synology NAS DS220 memory and was looking at Synology brand. I went with Crucial at 1/4 the cost of Synology and worksjust fine.

Ordered to upgrade memory in my replacement QNAP TS-453D NAS from 4GB to 8GB. Inexpensive upgrade which worked flawlessly. I try to stick with Crucial memory for all my laptop/NAS upgrades when possible.

My wife's laptop was so slow that she was nervous about using it. As RAM was running at 90% an increase seemed to be a good option. It was brilliant and the laptop now has a very happy user
Pros: Simple to install and works immediately increasing the speed and capacity of my laptopCons: Can’t think of anything
I can confirm this works perfectly in *my* Synology DS 720+, despite some people saying it produces memory warnings. It's memory. It works. That's about it.
Product quality is very high. Definitely recommend to other people. I used it for Synology DS220+ And it works well. Cost for ram is just right. Since I had really good experience over time with crucial I bot it. Crucial maintenance quality of product as always. Thank you.
Item was exactly as advertised. Prompt delivery. Works very well.
Works great with my Sybology NAS. While not officially supported works perfectly, and at like 1/3rd of the cost.
This RAM had the same specs as the synology preferred ram, which is $75 more than this Crucial RAM. I made sure to run a memory test using the synology assistant, and everything passed just fine. It also shows the proper memory size within Synology's DSM, with no RAM errors. Great memory for a much better price than Synology's RAM.
