I have read reviews of Drobo which say that Drobo is basically inaudbile, except when the HD’s are working. That is, that the fan is basically silent. But the fan in my Drobo is not. I can hear the air moving, which is normal and expected, but I can also hear other noise. It’s like a buzzing sound from inside the device. It’s basically loud enough that I can hear it anywhere in my living-room, even when I’m several meters away. And I have tried to place the Drobo in such a way that noise would be minimized (behind a wall under the stairs, outside direct line of sight).
Once the fan stops, the device is silent, apart from the crunching sound from the drives (which is normal and expected).
Should I look in to getting my Drobo replaced? I got it just few weeks ago (it was this noisy right from the start).
EDIT: I managed to record some of the noise. It’s a crappy recording, but you can hear the noise in the beginning of the recording. Is it normal?
