I'll keep the Kingston, though, as it is operationally functional for
copying purposes, with a slow SD standard across HandDroid and old PC
standards.

6 KB/s at a "Class 5" speed rating, I'm getting.

The last SD card I got (for that MP3 player -- out in the car or I'd
pull it for alooksee) not sure if it may be somewhat faster, but would
be a 32G card. I don't believe larger capacity SD, 32G, is longer
manufactured at slower ratings.

Slower SD is, perhaps being a misqualification, to apply to the MP3
unit for compatibility. I'd have to format a faster card from the
HandDroid and juggle around some MP3 files, get them copied to the
faster memory on a valid SD format -- transfer the card to the MP3
unit to see if it takes.

There are a lot more ratings and classes than a a couple Sandisk cards
I have, or a slow Canon 32G SD, I happened across from 5 or 10 years
ago, which I settled for (and first posted): working operability with
the Kingston adaptor, an older OS .and. this new HandDroid.

The MP3 unit as well accepts a standard USB flashstick for additional
external memory. I have it equipped for 96G storage: 64G USB + 32G
SD.

I believe in principle this HandDroid does the same thing, will accept
for augmented "system memory", for applications and storage, both
memory from USB and SD ports. (From a micro USB port fitting but of
course.)
