It's kind of a shame that Samsung's Galaxy S6 devices no longer accept microSD cards, because SanDisk's new 200GB card really pushes the storage limits.
200GB is more than what many notebooks ship with and SanDisk has made it possible to store vast amounts of data on a tiny card. The latest microSDXC card will have transfer speeds of up to 90MB/sec and will come to market during Q2 of 2015 for an SRT of US $400.00.
Oh, and if regular sized SD Cards are your thing, SanDisk has also released a 512GB Extreme PRO SDHC/SDXC card ideal for digital cameras and video cameras.
