Being rated A2 and very fast read and write speeds as well as having a stellar warranty and reputation for lifespan, these would be ideal for a Steam Deck, Android or Apple phone or other device where application load and smooth running are paramount. These are also ideal for photographers and videographers at 4K resolution (and some 8K scenarios, but not extended burst captures at 8K).

Note: make sure before you add to cart that yours says "Ships from and sold by Amazon.ca" under that button. If it doesn't, make sure to click the "New (?) from" box on the right, below the "Add to Wishlist" box, then select the seller that states, "Ships from Amazon.ca, Sold by Amazon.ca". I updated the 256GB card link above to directly lead to the sold and ships by Amazon version (it defaulted to 3rd party seller "Top Select Canada"), so verify before you add any of these to cart.

This same advice goes for anything you buy on Amazon, as long as Amazon actually sells that item and it isn't a 3rd party seller only item (still try to buy items that are at least "Fulfilled" or "Shipped" by Amazon as that still qualifies for Amazons free and easy returns).
