Great unofficial RAM for your Synology 220+ NAS
My current Synology 220+ RAM usage was constantly hovering around 70-80%. I started researching to see if any additional RAM could be added. You have a few options. You can go the Synology route and end up paying $90 for a 4GB stick. OR, you could purchase one of these for a fraction of the cost. Be aware that per Synology - you will void your warranty if you go with a non-Synology RAM. I took a leap of faith after much research and guess what?! This works perfectly. Installation was a breeze and my NAS recognized it immediately. It's been running so far for about a month with no issues. The best part? My RAM usage is now between 20-30%. Much better. I notice the OS runs a lot more smoothly as well now since the RAM wasn't being almost maxed out constantly. This is definitely worth the purchase if you would like to expand your RAM. Do your research. There are a lot of posts on Reddit that share the same success that I had. You could even go higher and get yourself a 8, 16 or 32GB stick. The 4GB was more than enough for what I use my NAS for (Plex and storage).

Simple ram to upgrade my NAS.
Simple, quick upgrade for my synology NAS that helps me get additional value from it, by being able to run more things simultaneously. Plugged right in, and worked right away.

Excellent, Works with DS224+
I had been looking to add RAM to my synology DS224+ and found this kit after erroneously buying a non-compatable stick. This allowed me to save around $60 without buying Synologys rebranded memory while retaining its compatibility. I had no error messages after installing and my system loads photos significantly faster. I've heard some say that this can void your warranty but my DS224+ manual states that the warranty will only be void if the RAM caused the issue. Maybe i'm living in the fast lane but i think this is a non-issue

Synology nas DS224+のメモリ増設のために購入しました。 メーカー推奨は高額で、推奨ではないですが、特に問題なく使えています。

Synology DS220+のメモリ増設にて純正品が高かったので他にないか探していたところ Crucial製のメモリを使っている記事があり試しに購入してみました。 特に問題なくSynology DS220+で使用できました。 導入後 まだ時間がたっていませんがエラーもなく警告もなく使用できています。

Paired the 4GB DDR4-2666 with the existing onboard 4GB RAM DDR4-2400 on my Acer Aspire 5 (2016) and it really does bring out the guns on FPS rates and even normal laptop usage when running on dual channel mode. Could be because 4GB is considered low nowadays, and adding another 4GB to bring it to a total of 8GB is the minimum required for gaming or typical laptop use. But, Crucial makes some great products and their RAM modules excel.

会社でDS220+を購入して、レビューサイトでこのメモリも使えるという書き込みを見かけて購入しました。 今のところ問題なく動作しています。 耐久性についてはまだⅠ週間程度なので評価していません。
