10 Best Micro SD Cards in 2022 (SanDisk, Samsung, and More)

Money is something we all understand. Micro SD cards start off at around $10 and end up in the $100 range. What makes for the difference in cost? Mainly, data storage size and data reading/writing speed. Then you’ve got the location of the manufacturer (whether it was made in the good old USA, or not). Of

Of course, expensive things are not always better; it all depends on your situation, and what you intend to use the micro SD card for. So figure out exactly what you need, and you might be able to scrape up a few nickels and dimes.

• CLASS2
• CLASS4
• CLASS6
• CLASS10

• U1
• U3

The higher the number, the higher the data reading and writing speed.

So we know the minimum speed. You can also find out the maximum speed of data transfer. You’ll see it displayed as “x MB/S,” where x is any given number and MB/S is megabytes per second.

Now to recommend 10 micro SD cards–including ones ideal for storing 4K footage. We hope you find something that appeals to you!

And as our phones get fancier and fancier, SD cards are expanding to take in more and more data. Most devices are compatible with SDXC cards. But if you’ve got something that was made before 2010, then it’ll probably take only SD or SDHC.

Now, let’s talk storage space. Let’s say you’re planning to load your smartphone with photos, videos, and music. For photos (if each photo is 14 megapixels), you’re going to need:

• 2 GB – about 340 photos
• 32 GB – about 5,400 photos
• 64 GB – about 10,900 photos

• 2 GB – about 20 minutes
• 32 GB – about 5 hours
• 64 GB – about 10 hours

• 2 GB – about 510 songs
• 32 GB – about 8,200 songs
• 64 GB – about 16,400 songs

So, you’re not planning to get the micro SD for your phone. In that case, how much memory do you need, exactly? Generally speaking, you need to know what sort of device you’ll be using the card for, how much space you need to store the stuff you have on it now, and how much more stuff you plan to store in the future.

So sit down, figure out why you want the card, and do a bit of math. It’ll save you money and time in the long run.

Speed classes are referred to in MB (megabytes) per S (second). Class 2 means data will be transferred at 2 MB/S, and Class 4, at 4 MB/S.

For UHS speed classes, U1 means data’ll be transferred at 10 MB/S and U3, at 30 MB/S. Just for reference, you’ll need at least a Class 10 micro SD card for full HD and U3 for 4K videos. Most cards now, thankfully, are Class 10, which means transfer speeds shouldn't be much of an issue.

You've got the memory, but what are you going to use it for? Here are some things you can use with your shiny new card (or at least supplement your growing electronics collection).
