Yeah, 256 GB on a memory card and to think that he was happy 10 years when he bought a box of 1,44 MB diskettes.
On the other hand, to get an idea, I'm using a "Hard Disk" (or HD, if you prefer) with a capacity of 320 GB, which means that 2 such cards would replace the HD and still had space.
This product will be made available by Lexar. The card was officially 400x SDXC UHS-I and can reach the speed of 60 MB / s.
Before you get excited, look at the price:
Nothing more, nothing less than 900 USD (90.000 AKZ) there in the USA, imagine then until arriving in Angola. The launch is scheduled for the month of October.
