I checked the size of the NAND Flash packages inside a MicroSD card and it’s two packages, if all it takes is two NAND Flash packages for MicroSD, why can’t we fit more of those tiny NAND Flash packages into a normal size SD card?
Currently a 1 TB MicroSD card uses 2x 512 MB NAND Flash packages.
I estimated a SDcard uses 9x 512 MB NAND Flash packages.
That would come out to ~4.5 TB SD card.
There are certain industries who would want a SD card that big.
And MicroSD cards are WAY too tiny & fidly, they are TOO easy to lose.
I miss MiniSD cards and I estimated that they can fit 6x of the MicroSD size NAND Flash packages, they could potentially bring that back as a form of easy to use, yet small Memory card for normal folks.
