Decided to go with the pricier memory from Synology because I decided the cost savings by choosing another memory chip brand wasn't worth it. I just want something that works perfectly.

4.0 out of 5 stars Works great but wish they didn't charge such a premium
Reviewed in the United States on June 6, 2023
Style: 4GBVerified Purchase
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.
