Thunderbolt 3 External JBOD in Hardware Posted December 26, 2020 43 minutes ago, gtaus said: I have 2 4-bay MediaSonic ProBoxes and another 9 external USB HDDs all connected via USB 3.0 to my DrivePool server. [...] It's an option to consider if you continue to have problems with your TB3 JBOD box. I didn't name a brand, but the MediaSonic was the USB 3.0 JBOD I was having trouble with. I got rid of that and built a small ITX PC with internal drives. That was about 5 years ago. I agree eSATA was more stable, but isn't an option in my current setup. I don't have any experience with Thunderbolt (JBOD or otherwise) so was looking for some input in that area. Glad your USB 3.x setup is working for you.
