Pegasus M4 randomly powering off occasionally

2026-06-21T04:04:59.2430000

I have a M4 Mac Mini video camera server connected to a Pegasus M4. Every 2 or 3 months or so, the Pegasus randomly powers off, making the software relying on it unhappy.

After I eventually discover the problem, I need to go to the unit and manually push the power button to get the disk array back on - which is particularly painful as I am frequently out of town - and count on these servers running withouth manual intervention. The power-off isn't super frequent - once every couple or 3 months - which I might not even notice if I were just using it for desktop operations.

I was hoping to move more services off of an even older Mac Mini server connected to an ancient Drobo Mini, but I afraid to do so, as it seems that ancient set up may be more reliable at this point.

Is this a common problem, or do I just have a bad unit? Is there a way for the disk array to at least auto-power on after it has shut down like that?

Pegasus M4 available in 0TB configuration?

Hello,

I just found out about Pegasus M4, and it seems to be exactly what I need!

The thing is that I've already bought the drives to populate the RAID (4 x Ironwolf Pro 12TB), so I'd need to buy the M4 as a diskless enclosure.

I've tried looking at the configurations offered by various resellers (in Canada) but it seems the M4 is so new that none of these resellers have even listed it, let alone the configurations available.

So, any chance a 0TB would be available?

Thanks!
