I went to format a brand new Samsung T7 external drive with the intention of formatting it as APFS - however no APFS topic is available.

It just shows the Mac OS Extended options and FAT options.

Any idea why APFS does not appear? Would it matter that its Mac OS Extended, when its going to be used as projects for Logic Pro only?
 
In Disk Utility, choose the View tab (or the View menu) and change to Show All Devices.
With your T7 attached, choose the top line for that T7 (shows the drive information/model number), then choose erase. You will now find that you can change the Format to APFS, if that's what you want.
If you still don't see that as a choice, make sure to change the "Scheme" to "GUID Partition Map". It is probably set for Master Boot Record, which won't allow APFS format.

What was your solution, for the next person who runs into this problem?
It was change to GUID Partition Map that worked

Yes it did it, in APFS is near 800mbps, while in others was near 700mbps

So weird how questions perennially asked on the internet can be answered definitively by one person somewhere without much fanfare or acclaim. Thanks.

This was the perfect solution trying to get my Samsung PSSD T7 Shield formatted as APFS:
Change the scheme to GUID Partition Map 👍
 
Delta Mac, big thanks for your post here. I couldn't figure this out and even found threads that omitted the key step of View menu, Show All Devices.

I'll add that one then needs to select the parent of the named drive -- the one right above the T7 Shield name (or whatever one has renamed it). It's in the sidebar and titled "Samsung PSSD T7 Shield Media".
