I am going to use a Treblet unit with a M.2 SSD in it. I am using it now with my Mini M1 and see about 1700 MB/sec read. For network storage I used a Synology NAS with 24 TB of available storage.
I have a OWC USB 3 enclosure on a M1 mini that the drives will disconnect on their own. I never let my M1 Mini sleep since it is my server. So you may want to see if you have the problem if the Mac never sleeps. I was working with OWC tech support and they are saying it's Apples problem. I have some inteck single usb to SATA boxes that work great, also my OWC thunderbolt box is also fine. I will be replacing the OWC USB 3 with something more reliable either USBC or TB..After reading this thread I picked up an Orico enclosure and the performance with a 2 TB WD850 is about 2800 read and 2600 write. However, every time my Studio goes to sleep I get the disk not ejected properly message that a few others have reported. Trying to decide if I want to return it for something else or just not let the Mac go to sleep. I have an older 1 TB SATA SSD in a Mokin case hooked up as well and it never has the issue - very annoying.
Hey, have you tried this:I have a OWC USB 3 enclosure on a M1 mini that the drives will disconnect on their own. I never let my M1 Mini sleep since it is my server.

Then check out system preferences to make sure the put hard drives to sleep option is disabled. That option appears again after being hidden by Apple for the last couple of OS versions. This was the solution from Sonnet support when I had dismounting issues using their PCI-E SSD Host cards.Open Terminal, and type:
sudo pmset disksleep 0
Hey, have you tried this:I used to own a MacPro5,1 with 4x 3.5" HDDs. Then I moved to a hackintosh with 3x 3.5" HDD and 2x 2.5" SSDs. I wanted to keep using 3.5" HDDs when I replaced my hackintosh with a Mac Studio.
I had a Sans Digital 4 bay external enclosure with USB3 and eSATA sitting in the closet and thought that it would be a perfect fit for my new Mac Studio...
Using USB3, I would get a bunch of "Did not eject properly" notifications every time I woke the Mac Studio from sleep. I purchased an app called Jettison that was supposed to eject external drives right before the system goes to sleep but it only worked some of the times and I still got those notifications...
Then, I purchased a Thunderbolt to eSATA adaptor to use with my enclosure. I no longer got the "Did not eject properly" notifications but performance would fall off a cliff on large file transfers...
Finally, I decided to just add the 4 HDDs to my NAS and set up a separate volume to use as dedicated storage for my Mac Studio. Performance over 10GBase-T has been excellent. No more "Did not eject properly" notifications.

That's ******.Yes, I tried that. Didn't help.
Over the weekend I got a OWC Gemini https://eshop.macsales.com/item/OWC/TB3DKP2D/. I have two WD RED 4TB drives as my Photo working drives. The unit is nice but I may send it back because my drives runs on the warm side, 40C. The fan is in the back and the drive bays are surrounded by metal so the fan is cooling the electronics and not the drives. My other OWC cases the same drives run at 28C. So for 24/7 I think I may want a cooler setup. Not sure what to look at next.
40c sounds fine to me. My room gets hotter than 28 in summer sometimes. I’d probably be disabling the fan at those temps and seeing how much noise I could get rid of vs heat. But that’s just me, still remember having systems that were almost too hot to touch but kept working.Over the weekend I got a OWC Gemini https://eshop.macsales.com/item/OWC/TB3DKP2D/.

Sequential speeds on my Crucial MX500 4TB are about where they should be in a Thunderbay 4. The weird quirk is that I only got full speed after chaining a monitor from that Thunderbay. Initial testing without the monitor was at ~80%. Random reads are also on target, but random writes are well below what the drive can do. That might be a macOS or AmorphousDiskMark limitation as the internal drive isn't much better.Can anyone share any benchmarks running a Thunderbay or similar TB3 SATA SSD external setup in JBOD / non raid mode? Interesting in how my unit compares.
from what ive read, most likely a sata controller issue.Sequential speeds on my Crucial MX500 4TB are about where they should be in a Thunderbay 4.

FWIW: I have two Toshiba MD05ACA800E 8-TB drives in my new-to-me OWC Thunderbay 4 (Thunderbolt 3) enclosure for which I have replaced the stock fan with a Noctual NF-A9 FLX using the slowest speed adapter. These drives are in Bay 1 and 4 (I have two SSDs in the other two bays) and the drives register 36°C and 34°C.Here are the current temps of the 2 drives in my OWC Thunderbay 4.

Are you happy with the temperature of your drives. My unit is differentit's a 2 bay model. The two drives have beet between 36C and 40C the whole time. The fan on my unit is not loud at all and I think the fan only draws air over the electronics. From what I am reading anything from 25- to 45-degrees Celsius is safe.FWIW: I have two Toshiba MD05ACA800E 8-TB drives in my new-to-me OWC Thunderbay 4 (Thunderbolt 3) enclosure for which I have replaced the stock fan with a Noctual NF-A9 FLX using the slowest speed adapter.

Seeing the temps of your drives, perhaps I should experiment with the middle speed adapter.
Update: middle speed adapter installed and the hard drive temps have not move at all in one hour of operation; exactly the same.
Given that A: the full-speed Sunon and the full-speed Noctua fans are louder than I would prefer and B: the low-speed Noctua adapter and mid-speed adapter both result in the same hard drive temp, there would seem to not much I could do so I'm going to stick with these.Are you happy with the temperature of your drives.

Can I ask how you are getting on with it? Are you using it in JBOD or a Raid mode? Any problems?I use a QNAP TR-004 on my Mac mini and will do the same on my Studio.
