1) Will this work in your phone or tablet? Probably — if your device says it supports microSD cards up to 128GB, it will accept the 200GB card.
2) Why 200GB? So far we've seen SD cards advance along a base 2 sequence, leading to iterations of 2, 4, 8, 16, 32, 64, and most recently 128GB. It'd be logical to assume that 256GB would be the next step, but instead just one year after the first wave of 128GB cards we're now seeing a 200GB card. While the SanDisk reps we spoke to were mum on why, we suppose we can see how they got to 200GB instead: 128GB + 64GB = 192GB, and that extra 8GB would be nothing. A proper 256GB microSD card is no doubt in the works, but for now it remains out of consumer reach.
so, its 2 Micro SD card in 1 card
ok, what about the price ?
3) Alright, alright: how much and when? Hold on to your knickers… worldwide availability is projected for Q2 2015 (so sometime between April and June) for $399.99
can't wait to use it on the new 3DS ....
i really should go with this line instead :
"Can't wait to test it on the Samsung Galaxy S6.....oh wait"
