I’m using ThunderBolt 2 cables with an adapter to ThunderBolt 4. I have two 1TB drives connected with identical cables. They mount just fine. But my G Speed RAID drive does not.

are the drives seen as drives (of any description) in Disk Utility?
The RAID drives do not appear in Disk Utility, but my two portable SATA 1TB drives do mount.
Are these rotating Magnetic drives or SSD drives?
Magnetic
what interface(s) on the G-Speed RAID box?
All connected drives have MacOS Extended formatting.
The RAID spins up, but doesn’t mount. I’ve tried booting without the RAID and then connecting it, but still doesn’t mount. I would get a new high-capacity drive that can be formatted in APFS, but I need some assurance that the formatting is the problem and not the result of a bug in Sonoma.
A drive that will not tell Disk Utility its make&model, and a reasonable non-zero capacity/size, can not be used, modified, repaired, or even erased.
Your power and connection method needs to be re-examined.
What PORTS are on the outside of the G-speed RAID enclosure?

Thank you for your help. The RAID drive mounts normally on my 2013 Mac Pro.

I’m using a power strip. Should I power from another source? When connecting to the Mac Studio I use Thunderbolt 2 cable with Thunderbolt 2 to 3 adapter. The same cable combo for my 1TB SATA drives, which mount.

There are only two Thunderbolt 2 ports.
The pictures I am finding online show two ThunderBolt-2 ports. But in the middle of the back is a USB 3 type-B 'printer' port, with a blue insert.
¿Are you quite certain yours does NOT have a USB-3 port?
Oh good. Glad my brain is still working a little bit. I do appreciate your help and it seems like trying to get the RAID to mount on the Mac Studio is not going to work.
I’m thinking now that I will have to purchase a new drive that can be formatted with APFS. But because my 2013 Mac Pro won’t recognize APFS and my Mac Studio won’t recognize a RAID running on Mac OS Extended, I’m unclear on how to transfer my 13TB of data onto a new drive.
If Disk Utility can not see your drives or the enclosure, the problems you are having are not file format (APFS Vs MacOS extended) problems, they are PHYSICAL connection problems.
It is possible you have a bad adapter, a bad port on your Mac, or a bad port on the enclosure.
I was hoping that a USB port would allow an alternate connection to clear that up, but it will not be possible.
Nope. Just the two thunderbolt ports.

¿Are you using the BACK ports on the Mac Studio?
The front ports are USB-only, and speed limited as well, except on the Ultra, which has all Thunderbolt ports all around.
I’m using the back ports. I wasn’t aware that the front ports were USB-only, so good to know.

doers the adapter show up? is anything showing as attached to it?
Sorry, I may have misunderstood. Were you referring to the back of the Mac Studio?
no.
That picture of the ports on the back of the G-speed RAID enclosure was exactly what I was looking for.
But very disappointing because it means no easy work-arounds.
G Speed RAID won't mount with Mac Studio M2, works fine on older Mac Pro?
