Here's a quick PSA for anyone who has been meaning to add more storage to a gaming handheld, GoPro, security camera or cheaper Android device: A handful of Samsung microSD cards we recommend are back on sale. The discounts include the 256GB Samsung Pro Plus and 128GB Samsung Pro Ultimate for $20 and $17, respectively. Neither of those are all-time lows, but they both come within $2 of the best deals we've tracked, and they're both a few bucks cheaper than the cards' usual street prices over the last two months. The Pro Plus is the top overall pick in our microSD card buying guide, while the Pro Ultimate is a faster upgrade pick. These deals are also available at other retailers, including B&H and Samsung.com.

If you're willing to trade some performance for more space, the 512GB Samsung Evo Select, the top value pick in our guide, is also down to $25 at Amazon. We saw this deal last month, but it still matches the card's lowest price to date. Typically, it's retailed around $30 over the last few months.

Which one of these is the "best" deal depends on what you're looking to do. The Pro Ultimate may be worth it if you plan to regularly stress the card in a device that can take advantage of its higher speeds. It was faster than the Pro Plus across the board in our benchmark tests, so it can save you some time if you often have to, say, move files to and from a computer. That said, the Pro Plus' sequential and random speeds weren't too far off, so it'll still be quick for recording 4K video, loading video game levels and the like. If you need a higher-capacity card but still value performance, it'll probably be worth the extra $3. For reference, the 256GB version of the Pro Ultimate is now going for $35, which is a fair bit extra.

If you just want a big chunk of space on the cheap, meanwhile, just go with the Evo Select. It's a clear step down from the other two cards in both read and write speeds, but it's performant enough for more casual tasks, and this deal gets you much more space per dollar. Many devices, such as the Nintendo Switch, can't fully take advantage of the faster transfer speeds of cards like the Pro Plus anyway. Like the higher-end cards, the Evo Select also comes with a 10-year limited warranty. None of the cards on sale here will be as fast as Samsung's upcoming SD Express models, but we'd expect those to be relatively expensive when they arrive later this year.
