Buffalo 3430DN Reviews

Replacement for my aging 3410D

By Jeff
Rated 5 out of 5
Date: 2025-11-19

I purchased this to replace an aging TS3410DN that failed because of a firmware update in October 2025. I updated the firmware and it stopped booting. I have used these NAS's fir over 20 years. And this was my first failure. Contacted US based support, the guy was from Texas and was excellent. Easily the best feature from Buffalo. We worked hard trying to bring it back to life, but was unable. I was able to recover the data from the drives myself with the help of software which saved me downloading the online backup. And just so you know it was a almost 6 year old NAS with 3 year old hard drives. After installing the new 3430DN and getting everyone in the office back online. I ended up formatting the first drive and the old 3410DN can still be used. These are very reliable units manufactured in Japan with US support. Even after this once in my life firmware failure, I still recommend them highly and I currently use 4 of them in my office. But remember to back them up just in case.
