I know. I couldn’t believe it myself. But it’s true. I saw this listing for a 200GB MicroSD card on Amazon. As of this writing it’ll cost you a cool $80, but that’s a whole 200GB!
I am a little confused at the strange denomination. Thanks to the bit system which ramps things up in multiples of two, we are used to seeing byte capacity go up in base-2 denominations going up from 2-bits, doubling up to 4-bit, 8-bit, 16-bit, and so on…. 32, 64, 128, 256, 512, ad infinitum.
So why is the next capacity SD card 200GB, and not 256GB?
Well… according to Sandisk, the circuitry can’t accomodate more than 200GB at this time. What we are seeing probably is a 128GB chip paired with a 64GB chip for 192GB.
Well, that’s still a lot of bytes. In practice you will see about 185GB usable in your OS explorer browser. But that should be good enough for anyone.
