DISK NOT EJECTED PROPERLY error mac studio 2022

Need help. I am convinced these drives are not compatible with Mac. I have a Mac Mini (Apple silicon), a MBP (Intel, 15") and I just upgraded to a new Mac Studio. I thought the Mini was causing the problem, and AppleCare had expired, so I upgraded.

I have a 1TB Extreme SSD that randomly disconnects

A 2TB Extreme SSD that randomly disconnected. I have an RMA to send it back.

The 4TB Extreme Pro was a great price, so I got one. But it now became corrupted on the Mac Studio. It won;t mount on the Studio, the MBP or an iPad. Using the factory USB-C cables and an aftermarket one.

I am very frustrated. The storage is so much faster than HDD-based, but the disks are unreliable.

I recently had an HDD crash (thank-you BackBlaze). So I am increasingly frustrated by external storage now. Thoughts?
