Here at the Strategist, we like to think of ourselves as crazy (in the good way) about the stuff we buy (like pillows), but as much as we’d like to, we can’t try everything. Which is why we have People’s Choice, in which we find the best-reviewed (that’s four-to-five-star reviews and lots of ’em) products and single out the most convincing. While we’ve written before about dash cams, printers, digital cameras, security cameras, and plenty of other things that need miniature memory cards to work, here we’ve rounded up the best-reviewed microSD cards that you can buy on Amazon. (Note that reviews have been edited for length and clarity.)
Best MicroSD Card With Adapter
“SanDisk always makes excellent products. Arrived quickly and worked flawlessly and still kicking. Love their products, and I love that they come with SD card–size adapters to make it easier to transfer files or use in cameras or devices that still use SD slots. I personally use their microSDs in phones, consoles, etc., and they’ve never once let me down. For the price, you can’t beat it.”
Best 128-Gigabyte MicroSD Card
“I don’t own a device with a microSD port that doesn’t have this card in it. Nintendo Switch, Samsung Galaxy S5, Samsung Tab Pro 10.1, GPD XD Plus, Nintendo DS, Nintendo New 3DS, and another one in a USB thumb converter that I use for MP3s in my car radio. I effectively use this card all the time, and I can’t complain. I don’t know about exact stats and benchmarks, but movies, games, and music don’t stutter (unless it’s a Wi-Fi issue), and I write and read to them without problems.”
Best 64-Gigabyte MicroSD Card
“Frankly, it’s amazing to me that something so small can hold so much data, especially when it works as well as this 64 GB microSD card. I put this in my Galaxy S8 so that I could store my music on it. My phone already has 64 GB of flash memory built in, but in the future when I upgrade my phone, all I have to do is put my SD card in it to keep all of my music. Would definitely recommend.”
Best 32-Gigabyte MicroSD Card
“The Silicon Power 32 GB microSDHC card is perfect for what I need. I tested this on a weekend away, and it worked really well … This is a Class 10 microSDHC card and can transfer up to 85 megabytes per second. That’s just super quick! Transferring my photos now takes seconds instead of minutes. It also comes with a standard SD card adapter so that you can read it from most PCs or Macs. This is a fantastic microSDHC card, fast and robust, and it’s reasonably priced, too. Try it, I don’t think that you will be disappointed.”
Best MicroSD Card for GoPro Cameras
“Excellent card for my GoPro Hero 5 Black. Plenty of storage. I can get four hours and 38 minutes of recording on 4K UHD or five hours and 38 minutes on 2.7K. Speed is awesome with video being silky smooth and very responsive. Thoroughly recommended to anyone wanting some great microSD storage.”
Best MicroSD Card for Kindle Tablets
“Got this card to expand the memory in my new Kindle Fire HD 8 — It works great! Easy to install, and within an hour I had moved my apps and books all over to the card and re-downloaded movies. I can finally have all the apps I want to use, and several movies and shows downloaded in a much higher quality than before, with no effect on my Kindle memory.”
Best MicroSD Card for Samsung Phones
“Best quality, best buy. I couldn’t believe when I saw that Samsung was selling these at such a great price. Not much more than the cheaper brands out there, but for quality and speed, it’s incomparable. I’ve bought these for my Samsung Galaxy 4 and my Samsung tablet. Easily recognized by them, installation was quick and easy. I have freed up more space on both my phone and tablet while being able to keep everything I want on them at the same time. I will be buying more for my camera, too.”
Best MicroSDHC Flash Memory Card
“I decided to wait a bit to review this high-capacity (SDHC) card and it has been over a year now. I have to say, there have been no problems using it as external memory on my media player. This little bugger does what it says and does not fail. Transferring files onto the card went very fast and without a hiccup.
Just some cautions: Make sure you use this ‘HC’ card in a player that is compatible. The ‘high-capacity’ card is not backward compatible. In short, it will not work if you don’t have a device that can utilize the ‘high-capacity’ format. Although most devices that support an ‘HC’ card will usually support a regular SD card … Five stars for this little powerhouse and no complaints due to its solid performance over the last year.”
Best Budget MicroSD Card
“Bought for my HTC Hero Android phone, to replace the stock card. Recognized immediately and worked without difficulty. Linked to my PC and transferred files from the old microSD card. Smartphones are complicated enough, so it’s a relief when the subsystems work easily. Love the quality and the price. Remember ‘Patriot’ when you need a fast, affordable microSD card for your phone or tablet.”
