Having been happy with my Drobo for years (and it still works perfectly) I'll pass on this system.
1.) Drobo basically no longer exists so my drive is a ticking time bomb.
2.) Other companies such as Synology and QNAP were around back then making drives and still are. So I'm going to upgrade to one of their systems.
3.) suggestions welcomed, and I'll check Ugreen out, but I don't want to get hosed again.
Drobo is such a disappointment...
I bought into the Drobo vision in the beginning as it seemed to be exactly that I'd hoped: an inexpensive, low maintenance, direct attach drive bay that I could mix and match whatever drives I had laying around to build out for bulk storage.
Then I wanted to switch to 2-disk redundancy, so I updated to a larger drive and needed to let it repair itself before I could switch the redundancy setting-- since the new capacity exceeded the max the file system could support it added a separate volume to account for the added capacity. Turned on 2-disk redundancy, the capacity contracted again, but I couldn't get rid of that zero sized volume. I contacted support to see if there was a way and they refused to answer the question without me entering into support contract.
The answer to the question for all I can tell, was "no". I can't remove that useless volume and was doomed to have to manually eject it for the rest of the life of the Drobo. That's a problem. The bigger problem for me was that they essentially wanted hundreds of dollars for that one word answer that should have been listed in their documentation somewhere.
Then I started to realize that their file system is completely proprietary and the longer I used that device the more I was going to become dependent on a company whose business model was extorting support contracts.
Anyway, that's a long story to get to the point that I switched over to Synology and have found their hardware to be solid and their support to be quite good. I get an answer if I have a question, their forums are well trafficked, and the one time I had a power supply glitch they replaced it without hesitation.
I do worry that Synology is getting confident in their market position and they seem to be slowly tightening the vice on licensing for some parts of their system-- it's hasn't affected me yet but, AI nonsense aside, I'm glad to see there's another viable competitor coming online to keep them humble.
