Theoretically it’s possible to make an SD card with up to 128TB of storage. But until now you haven’t been able to buy an SD card that could hold more than 512GB of data.
That changed this week. Lexar just introduced the world’s first 1TB SDXC card, called the Lexar Professional 633x SDXC card and it’s a UHS-I card with support for read speeds up to 95MB/s.

That’s not entirely true.
