The base storage for the Galaxy S10 lineup is 128GB — which is an insane number considering it was nothing more than a pipe dream for smartphones storage five short years ago — but that's just your storage starting point. Because Samsung phones include a microSD card slot, you're able to add as much extra storage to your phone as you want, up to 512GB. We've rounded up your best options.
The Samsung EVO Select offers the best value with larger storage options available. The 32GB card offers ample storage at a bargain price.
This 64GB Samsung EVO Plus microSD is a great value that comes with a USB card reader on a lanyard for easy file transfers.
PNY's 256GB card is arguably the best value you'll find for a microSD of this size, but PNY offers plenty of storage options up to 512GB.
With read speeds up to 100MB/s and write speeds up to 90MB/s, this 200GB card from SanDisk will let you record in HD or 4K to your heart's content.
This Class 10, UHS-I microSDXC card from Kingston features a 256GB capacity and advertises read speeds up to 80MB/s and write speeds up to 40MB/s.
Samsung's 512GB microSD card is worth it if you know you're going to need that much storage, and arguably the best to get 1TB on an S10.
How much storage is enough storage for you?
Everyone's digital storage needs are different. If you've got a massive media collection that you want to be instantly accessible on your phone at any moment, you'll need to find the microSD card that suits your storage needs without breaking your budget. Samsung offers some impressive options for its latest flagship, including a version of the S10+ that offers 1TB of internal storage for an insane amount of money. For those of us who just physically shuddered at that price, you can get close to that amount of storage with a little help from a much more affordable microSD.
We've rounded up the best options at every price point and popular storage capacity so that you can find the right one to fit your needs. The best value is the Samsung 32GB Evo Select. Evo Select feels like Samsung's budget line of cards, but that's just because it's an Amazon exclusive that's regularly discounted. In terms of performance, you'll get the same great read and write speeds with storage options up to 512 GB.
SanDisk is another trusted storage brand, and they offer what I would call the "Goldilocks" solution with its 200GB Ultra card that sits between the 128GB and 256GB offerings. However, if you really want to go all out, we'd recommend the 512GB Samsung EVO Plus which is basically the exact same card as Samsung's Evo Select brand except for it's red, *feels* more premium.
