The Galaxy Note 9 is the first Samsung phone to offer official support for 512GB microSD cards. However, the company didn't have a 512GB card of its own to offer alongside the phone when it went on sale around the world. But Samsung did confirm that it would release a 512GB card at some point, and it is now listed officially on the company's website in Germany.
Samsung's 512GB microSD card is quite pricey
Samsung's 512GB microSD card is part of its EVO Plus range of cards. It's a class 10 card that can reach read and write speeds of 100 MB/s and 90 MB/s respectively and can store up to 24 hours of 4K videos and 150,300 pictures. And it comes at a premium, as expected. Samsung Germany has it listed for €289.99 ($330), which is nearly the price of the mid-range Galaxy A7. It's also nearly triple the price of a 256GB EVO Plus card, so buying a 512GB Galaxy Note 9 would be a more affordable affair. And the price isn't likely to drop anytime soon, although it should become cheaper in a few years as demand for higher storage capacities continues to rise.
Samsung isn't taking orders for the card just yet and doesn't have a release date mentioned on its website. It's also unclear just how many markets the 512GB card will launch in. Of course, you could always opt for 512GB cards from other manufacturers if you need all that storage on your phone right away.
