Well the issue the folks over at xda-developers were warning me about was that SD Card flash drives formatted as adoptive break down with the constant writing and rewriting that apps perform. They don't reliability hold up, and unless you choose one that's fast, can cause sluggish performance. The 64 GB card I got was a pretty cheap one.  A while back I bought the fastest USB 3.0 flash stick I could find to load a portable copy of FooBar2000 onto, and it's still horrendously slow stating up and shutting down. If there are specific commands to run in adb shell that would designate the added storage space as being specifically for data storage purposes, that'd be great.

I also haven't found information on whether of not the 'sm list-disks' command, which in my case returns as 'disk:179,32', returns just the designation of the added sd card, or if that includes the existing internal memory. I see the 'sm list-volumes' command returns 'public:179,33 mounted 38C4-18FE', and know 38C4-18FE represents the sd card I see in Amaze. Past mistakes running Windows diskpart have made me very cautious of running any commands until I'm certain what they are going to do.. I sure don't want to run a command that will format the original internal memory. I'm okay with the card staying as dedicated internal memory.
