## Questions & Answers

**Q: Any reason why one can't use a crucial or samsung ram which is same speed for a fraction of the price?**
A: SAMSUNG M471A1K43CB1-CTD 8GB DDR4 will work and not give warnings. Also,  it's double the memory for half the price.

**Q: Just wondering why this is  $90 when you can buy an equivalent piece for $30 elsewhere?**
A: I use cheaper modules and they work fine

**Q: Compatible with DS2419+?**
A: For the price of Synology Branded memory and the fallout for having gotten it wrong, do not trust this type of Q/A to some random stranger off of amazon.  Open Synology's official documentation about what memory is supported in what system and go off of that.

**Q: Is this a synology oem part (d4neso-2666-4g) or is this an off-brand?**
A: It’s Synology branded RAM

## Customer Reviews

### ⭐⭐⭐⭐⭐ 安心の純正メモリ
*by ぱ***ん on July 6, 2024*

Synology NASキット 2ベイ DS720用に購入しました。ネット上では純正以外のもっと大容量のメモリでも認識するとの情報もありましたが人柱になる勇気がなかったので。（笑）当然のこと全く問題なく増設できました。同時購入でSSDも増設しているので、どちらに効果があったのか良く分かりませんが、とても快適に使えています。NASはOSの載ったネットワークPCみたいな物ですからメモリは多いほど良いと個人的に思ってます。

### ⭐⭐⭐⭐ 純正品
*by ジ***オ on December 26, 2023*

保証の関係で、純正品を選ぶ必要があります。

### ⭐⭐⭐⭐⭐ 増設は「善」です
*by I***U on May 13, 2024*

DS224＋用として購入しました。NASはほぼ放置していれば良いだけで、かつバックグラウンドで夜中とかに働いてくれるし、動画編集や重い作業をしなければ、わざわざメモリを増設しなくても普通に使う分には申し分のない速度が出ています。よって、ノーマルのままでも十分なのですが、DS224+はメモリの増設ができる製品であること、長く使う物なので安心感と将来的に重い作業が発生してもストレスにならないために、初期投資と考えてDS224+本体導入後すぐに購入しました。結果として、現在は単なるバックアップと日々のデーター保存先としてしか使っていませんが、写真や動画の出し入れは、当たり前でしょうが体感的に早くなりました。PCのメモリ増設で性能が格段にアップする経験はありますが、NASでもこんなに違うのかと感銘を受けた瞬間でした。実際のところ、NASで大きなデーターのやり取りをされる方、大人数で使用されている方にはメモリ増設は必須で、ほぼほぼバックアップにしか使わない程度の私にはオーバースペックというのは承知の上ですが、リソースモニター上でメモリが余裕のある動きをしているのを見ると安心できます。安くはありませんが、少しでも欲しいなと悩んでいる方は、ぜひ購入してメモリ増設の恩恵と実感を早めに受けられると良いと思います。増設したことを後悔することはないでしょう。
