2**18 + 2**9 + 12. A peculiar number. I wonder how they chose
that?

Why not? Personally, I would find it embarrassing if the Corsair thumb
drive in my pocket held more data than our largest mainframe volumes.
But, that's just me...
Would that be 54 GB? You have a thumb (flash?) drive bigger than that?
54GB?! Is that from another discussion? As I indicated, our large
volumes have 262,668 cylinders. Each 3390 cylinder holds 849,960 bytes,
so these large z/OS volumes hold over 223GB each. (Yes. I agree that's a
strange number.) The latest ones hold 1TB each.
My Corsair thumb drive holds 64GB, but the latest ones hold 128GB.
