If 128GB isn't enough space for your porn collection then I have some good news for you. SanDisk is showing off 200GB microSD card, a 56% jump on the current highest capacity microSD, which is 128GB.
SanDisk isn't sharing the specific details on how they pulled this off, but they did say that they achieved the higher capacity by using a proprietary design and production process for the chip in the card.
Whatever that process is, it looks like SanDisk may have come up against the limits of current tech. While Flash storage usually doubles in size (1GB, 2GB, 4GB, etc) the new card is not even close to double the storage of the next biggest microSD card (128GB). This suggests that SanDisk is has run up against a limit on just how tightly they can squeeze in the Flash.
The new card supports data transfer speeds of up to 90MB per second. It's going to be available next quarter for $400.
