Fits Synology DS224+ perfectly
Wanted top performance from my new Synology DS224+. This RAM fit perfectly, was easily installed, and it is performing flawlessly. Highly recommend.

Was plug and play
Used on my Synology DS220+. Install was a breeze, start up and NAS recognized with no issues. A little pricey but worth it.

Works great in Synology NAS
Bought this for a DS923+ and it's worked great as I'd expect from a first party product. Worth the cost not to have to worry about compatibility.

Works great but wish they didn't charge such a premium
I'd ordered no-name memory first and it did not work. I returned it. Then I ordered this official memory upgrade and it did not work either! I contacted Synology support and they sent a replacement NAS DS220+. No problems installing this memory in that replacement. Love the boost in resources but wish that there was not such a significant price difference between this and the various no-name alternatives.

Good for RAM boost
Great for the Synology NAS however a little expensive.

Perfect for my symbology nas
I wanted to buy genuine memory but it’s typically way overpriced. I got 4 gb of official memory for 20 dollars - which is still a bit expensive for what it is but that’s dirt cheap for official memory. I got it because there were times with the 2gb stock memory that we’d get some buffering, between me and my kids. There’s no issue since installing the extra 4 gb. If you can get it cheap it’s great.

Nice to put them back to use.
I was kind of surprised that I could find a match to this unit. I was filling out the memory of a NAS drive and I needed a mate to an older memory card that I was recycling and I was pleased to find one. This way I only had to buy one instead of two new cards and I dug a spare one out of my scrap parts box.

Easy, plug-and-play with DS220+
Worked as described in my DS220+. Nice to have the additional memory to run more VMs, containers, and full-text search. Went from the stock, soldered 2 GB to at total of 6 GB. I have a pair of 4 TB HDDs running in RAID 1 on this NAS.
