External SSD drives continuously disconnect then reconnect new M2 Mac mini pro

On the next port over, it happened twice while I was using the computer. It just popped up the error message, but the drive still showed on the desktop and was immediately accessible. So it doesn't have to be sleeping or display off for it to happen. Also, I plugged in a card reader to transfer a file to that drive, and half way through the transfer it gave me an error that some of the data in the file couldn't be transferred. After that, the SD card wasn't readable at all, and wouldn't eject, and I had to restart the mini to make it readable again. Once restarted the file transferred fine. Something is going on in that usb bus where the bus will just drop occasionally. Putting more load on it seems to trigger it more often, but this situation is completely unacceptable. I'm willing to listen to any other suggestions, but my 7 year old iMac is looking like a better option than this 2023 mini pro at this point. Think this just needs to be replaced honestly.

Dropped once in 24 hours on that port, which is one time too many. On to the next port down.

So one of the thunderbolt ports is going to the Studio Display. I now have both SSD’s plugged directly into the display. The hub is still connected to the mini directly. Would it be a problem to have two or three hard drives plugged into those thunderbolt ports, I would’ve thought that would have been no problem? Those SSDs don’t have spinning platters, so they don’t draw very much power.

No, but I really have a hard time with that being the issue when it is happening to multiple devices on multiple ports. Additionally, I've never had a single problem with these peripherals on my MacBook Pro or my iMac.

as an experiment I just plugged the 2 sandisk drive into the studio display to see if that changes anything.

Sorry, for clarification, neither of the SSDs were plugged into the hub, they were plugged directly into the mini.

and just now while typing this, with the san disk drives plugged into the monitor, the satechi hub drive unmounted and remounted.

Split the drives across the 2 buses as you suggested and it happened 4 times overnight, twice for each drive. Adjusted that display setting this morning and will report back this afternoon.

did that this morning and so far no drops. Hope that's the solution.

nope
