If you have a big media collection, getting a small microSD card for your Surface Pro 4 can make your storage situation worse. Don’t split your files across multiple cards. Instead, go with the Lexar 256GB High-Performance MicroSD Card.

For reference, this is enough storage to handle 58,000 songs. Despite having all that storage space, this card still transfers files at 95 megabytes per second. That’s on par with other cards in this round-up.
