My Drobo 5D3 has been making drive noises, pretty much non stop for weeks. I have tried turning off every service and application I think of, but nothing makes it stop. It even keeps making drive activity noises when the host Mac is being rebooted! Also, IO performance is pathetic, see attached image.
I recently had to replace 2 x 4 TB drives, 1 at a time, over a couple of weeks, with 2 x 6 TB drives, as the capacity was getting low. The Drobo mis-identifies the 2 6 TB drives as ‘SSD’ drives.
There is an mSATA card in it, and the health is reported as ‘Good Life (47%)’
Any ideas? I am ready to chuck this thing
