Cloning NVME Drive

I have an M4 MacMini sitting on a Satechi hub with a 1TB NVME. The OS is still on the MacMini with some applications and data on the NVME drive.
I am having many problems with external drives (e.g. Time Machine; Super Duper; Photos and Music) frequently not being recognised.
I have decided to deal with some of these problems by replacing the 1TB drive in the hub with something bigger to at least hold the photos and Music.
I can't face doing the whole reinstallation and want to just precisely replicate the content of the 1TB drive onto a bigger drive of same type, e.g WD Black SN850X M2 2280
Any advice would be greatly appreciated.
 
I don't see why Carbon Copy Cloner wouldn't do what you want. The only limitation is that they no longer fully support bootable clones, but you don't want to do that (if I understand what you're saying). Now, if there are problems reading the old disk, that's another matter. But my experience is that Carbon Copy tries very hard to copy everything and will do a better job with a sketchy disk than a straight Finder copy.

Is your Satechi hub have its own power supply or using the mini for power?

The Satechi MacMini hub does not have its own power supply. It relies on the connection to one of the 3 Thunderbolt ports on the back of the Mac Mini M4

Unfortunately, I believe the mini M4 has inconsistent power delivery from the USB-C ports during sleep/low power mode. Many threads from mini M4 owners regarding disconnecting drives attached directly to the ports. Adding a powered hub resolves the disconnects.

I was considering this and the Caldigit seems the best, but too expensive for me, so I think I will go for the OWC Thunderbolt 4 11 port
 
Going back to the original question re cloning NVME drive, would Carbon Copy Cloner be any better/ easier/ safer than SuperDuper?
I would stress that the Satechi NVME drive is used to increase storage on the basic Mac Mini M4 with the OS still on the Mini
