Look at the fingernail on your little finger. That's roughly the size of a microSD card, which can now hold a whopping 200GB of data thanks to SanDisk.
Available sometime in the second quarter of 2015, the new microSDXC card uses the same technology that SanDisk developed for the 128GB microSDXC card it introduced last year, but with an improved design allowing the company to increase storage capacity by 56 percent.
The new card also boasts transfer speeds of up to 90MB/sec.
