(R)evolutionary Flash Storage

There is something going on with flash memory. It is getting more affordable than ever. This SanDisk offer on Amazon makes the case for a micro-SD card slot in a phone.

Apple charges $400 for an upgrade from 512GB iPad to 1TB iPad. That is $80 per 100GB. Expensive. But the SanDisk price at $60 for 400GB means 100GB is $15. Yes you can have 100GB of flash storage for the price of a breakfast in a street cafe.

This puts whole lot of things in perspective. My entire photo collection (in RAW format since 2012) is 500GB and that includes dozens of night sky exposures for stacking. I guess  typical amateur photographers don't do that. My entire music collection is 100GB.

It seems an SD card is an evolutionary product. But the capacity/price shift recently has been revolutionary.
