Are you an expert in this technology to have an opinion? I'm not, but I read around to learn. For instance, right after launching 128GB MicroSD by SanDisk I have read that it was not painted in red-gray because such a painting would take valuable microns of the card's thickness. Also, I remember that nobody but SanDisk was able to produce 128GB MicroSD for half a year. All these mean that technology has reached its top.
mein friend, belive me, technology is far from getting close to the maximum potential. there are pure crystal webs into crystaline webs data storage options. it is supposed that it would be absolutley indestructible, and it would be much much smaller and cheaper than what is done by these days.
also, i know a lot more about other solutions for storage. let me just say that there is a lot that has not been done yet. and it will be done. not yet, but it will. a few years ago, one would laugh when you told him that there would exist ultra FHD display on phones that will look good. they are here, and cost 50$ a piece, even less.
sandisk is just lagging around, because they can make a lot of money off not going straight to 2TB microsd cards. around 2 tb is the place where the fun really ends, because the entire protocol is limited to 2TB. I am curious in how much time, they are going to touch 2tb, and what will happen then.
flash cannot get over 2tb due to fat32 format, exfat is not open, ntfs is not made for flash, writing a new arrangement code is probably what will happwn, but it is going to be fun.
until then, i really watch them and laugh while they throw a 200 gb card for 2X launch price of a 128card.
i remember buying a 64 gb microsd card in 2010. it costed me 150$, there was no real sign of them ever getting bigger. i got two 64 gb cards for 50$ from samsung original, this year.
