Nintendo has partnered with Western Digital to create officially-licensed memory cards for the Switch. The microSDXC cards will come in 64 GB and 128 GB versions and feature the Nintendo Switch and SanDisk logos.
Two packaging designs will be available for the new memory cards: one Mario Kart 8- and another Breath of the Wild-themed. Nintendo's golden seal, indicating that the products are indeed officially licensed, will be located on the upper-right corner, directly across from the red-and-white Switch logo. The two designs will otherwise look similar to standard SanDisk packaging.
Speeds for the 64 GB microSD card will reach up to 100 MB/s read and 60 MB/s write. The 128 GB version features the same read speeds but has a max write speed of 90 MB/s. The cards will be available at select retail stores starting in October.
