UPDATE 2: Beelink s12 still holding strong.

Got the following from Beelink customer service:

"Regarding the question you asked about the output power of the machine’s USB interface, the answer is 7.5W.

If you want to use external hard drives on the USB interface, it is suggested that do the following solution：

please uncheck the save energy in the device manager-- universal serial bus controller–USB hub-- properties–power management—uncheck “Allow the computer to turn off the device to save power”

As for the g3 usb/ssd issue, it’s case closed for now with root cause 5 W max per usb port.

As for this useage case: s12 > pi 5 >>> g3plus.

My opinion is that the Beelink gear is better than GMK based on my experience with s12 and s13 versus g3plus. The Beelink stuff has way better aesthetics and build quality in my opinion.

Hope this was enlightening, I learned a lot. Thank you. Peace.

UPDATE: s12 handles both ssd out of the box and reboot and continue to hold. Devices are superspeed 20 gb and ~900 ma. Setup is headless, there are no other peripherals. Will see if this holds.

Okay, so what does this point to, I plug the drives into different devices and they work. What would your next troubleshooting step be? I have a backup hub and cable, if that fails the same thing on the device what does that point to? Both ssds exhibit the same behaivior on g3 and work on other devices.

In fact I have not collected a single piece of evidence that implicated the drives other than they come unmount on g3.

So no, I don’t think so. Also there are various lines in dmesg -w that tell the story but I don’t have them to share with you and I am frankly done working with the g3 so I will not be going to collect them and bring them back.

So, sorry for saying there were no errors, but there were no smoking gun errors other than dmesg showing the drives behavior and lsblk and cockpit storage logs which helped me determine 100% and beyond any shadow of a doubt in my mind that the problem is with the g3 and not the drives.

I am returning the g3 and keeping the drives. I am convinced and not swaying. Got it?

*If the ssd fails on s12, I promise to create a post solely focused on THAT issue and will provide full error logs for anyone interested and admit I was wrong but still just trying to learn.

**another approach: what errors would you expect to see if there was an issue with the usb bus providing power? What errors would you expect to see if there was an issue with the usb drives themselves? Then check those results gainst the fact there were no errors. What does that imply?

***maybe we are thinking the same thing: the issue IS with power and in this case the power comes from g3. I admit it is possible that the drives would work with a powered hub. I don’t have one. I am going to try to see if s12 will support these drives without a powered hub before I invest in one. From my point of view: the issue is with g3 because it’s not supporting the drives, but that might be the misconception that I will unlearn during this process of reeducation.

**** one more level deeper, if what justpassingby says is true and the GMK can only support 5 watts per usb port, what happens when the ssd device draws a current greater than 1 amp? What about when two do it atthe same time? That is what I believe is happening. The g3 looks to support 20 W / 4 on the usb ports based on justpassingby. The raspberry pi 5 does 45W / 6 peripheral ports and this is the reason why the pi 5 did not drop the ssd and G3plus did; for this application pi 5 >>> g3plus for that reason. The only info I can find on beelink s12 is 25W max and 5W idle, no idea what is allocated to the usb ports but WE WILL SOON SEE. The snag with pi 5 was with the os and python version not being consistent for HA (I believe). I am hoping for the result s12 > pi 5 >>> g3plus.

Thanks yes trying to power ssd direct from the usb port. This is likely a bad unit but there are broader implications here for using direct usb ssd on these devices due to power draw. I had no idea it would be a factor but it definitely warrants consideration in designing a setup. Thank you.

Noted, I definitely did not understand or appreciate that before but now I really know for sure, thank you.

Thank you kindly, there is no error message per se that is the smoking gun, I use dmesg -w, lsblk, and cockpit storage logs to troubleshoot and it comes down to the power draw in my estimate. The ssd simply unmount themselves, nothing dramatic. It is entirely possible that a powered hub would work with this g3 that I consider a lemon. Truthfully, the g3 “looks less nice” versus beelink and if they have 5W max per usb, I could see how they might disconnect with voltage spikes, but this thing never mounted one of the usb ssd on 3 of 4 ports. Right from the start, I am thinking the usb bus power connection is where the issue lies. It a lemon of a cheap unit.

I cannot find the info on s12 yet and somesaid in a different comment they had to email customer service to find out g3 had 5W max. Hoping s12 will reliable hold mount, but I can see where I still may need to invest in a powered hub. Thank you.

Thank you, yes as this relates to my issues I have the concern about mini pcs being able to keep ssd mounted indefinitely via dedicated usb ports. The 5W figure is less than I hoped, I was hoping for 10. Will state again, the issue with the g3 was immediate and after testing I do believe it was a lemon. That said my experience here has opened my eyes to the limitations of these devices. Admitted that I am shooting for absolute minimum power consumption and using the cheapest shit I can find. Thank you for the data point on pi4bs, will be interesting to see what I get with s12. I can report back if it is of interest.

I am open to the pi because I got so fucking close with it, period. I flashed the pi 64 bit os lite to one of the two ssds, I had Samba running with backups from s13 and Meerkat it was beautiful! Homeasistant fucked my world up: I was trying to run in container, I tried both docker and podman. There was problems with the image pull, pi would time out and or the ssd would get corrupted. I crashed this system and rebuilt it so many times before I gave up. I do believe it could work but I thought I might have abetter chance with a mini PC. And BTW, I really like the s13 so I kept moving that way. I fucked up with the choice on GMK, I should have got another Beelink I thought because the Beelink iss noticeably nicer and the GMK looks more trashy and was a lemon to boot.

If I simply dropped HA or moved it to another device, pi did what I would need. But I did not want to and am too stupid to make it work with pi so far…

if I did it again, I would probably not flash the os to the same ssd that I want to use for backups, that was probably stupid move, and would probably be able to make it work I would probably need a powered hub for the ssds and boot media because of concerns there and it would probably cost the same as an s12 and since I really like the s13…

*also want to add that I am a rabid hobbyist and have a list of uses for pi 5 so it is NOT going away or in the trash, just saying

In that regard I will say that I ran the ssd successfully on raspberry pi with no issue whatsoever so i never considered it. The issue with GMK was immediate and affected both ssd the same way, I methodically tested all the ports one by one with both ssd and concluded the issue was with gmk and not the ssd. I tested ssd on separate device Meerkat to verify the drive and hub and cable, no issues found with the ssd, hub, or cable on separate device and with smartmon i even wiped the drives and partitions just to be sure, testing was thorough enough for me to conclude that I received a lemon.

But hey, maybe I am wrong and if I see the same thing on s12 I will need another option, but I would be more inclined to believe it is a USB power issue and not an issue with the ssd because that is what all the testing points to so I am wondering: am I wrong to think I can sustain two ssd via USB with s12?

Please any advice. Thank you.

It sounds like a pirate which is me.

If it happened to you in 1999 then you are just probably dumb as fuck because plenty of available information across the nation (~$16-18)

If it happened in 1992, you would be big sad and harder to find out more info pre-buy ($10-12)
