The Basics of Micro SD Cards

You’re looking through a shelf of micro SD cards, and you’re beset by computer terminology, jargon left and right. Leaves you pretty clueless on what to buy, right? Let’s go through the basics.

The Simplest: Cost

The Simplest: Cost

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.

Micro SD Card Specifications

Next, we move into the technical specifications of micro SD cards.

SD, SDHC and SDXC: What’s the Difference?

SD, SDHC and SDXC: What’s the Difference?
When it comes to micro SD cards, you’ve got 3 main formats: SD, SDHC and SDXC. The main difference between them? Data size. SDXC is the largest, followed by SDHC, then SD. SD cards usually go up to about 2 GB, SDHCs range from 4-32 GB, and SDXCs will hit 64 GB or more.

Class Tells You The Minimum Data Reading/Writing Speed

Class Tells You The Minimum Data Reading/Writing Speed
You want a fast card, you look at class. Class tells you the minimum speed at which your card’ll write.
There are two speed classes: the “SD speed class” and the “UHS speed class.” The UHS (ultra high speed) speed class was newly introduced in 2010 and is much faster than the SD speed class. If you want to utilize this ultra high speed, though, you need a device with UHS interface; otherwise, you’ll be bumped back down to your SD speed class.
The SD speed class has four categories:
  • CLASS2
  • CLASS4
  • CLASS6
  • CLASS10
The UHS speed class has two:
  • U1
  • U3

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

Maximum Data Transfer Speed

Maximum Data Transfer 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.

How to Choose a Micro SD Card – Buying Guide

Now that we’ve covered the basics, let’s go over to how to choose the perfect micro SD card. We’re going to dive in deep, covering aspects such as durability and compatibility.

Make Sure it's Compatible With Your Gadgets

Make Sure it's Compatible With Your Gadgets
SD cards have always been in cameras and computers. Now, they’re infiltrating into smartphones and gaming consoles. (Nintendo Switch, anyone?) The type of memory card you need will depend on the kind of gadget you’re using. 

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.

It’d be rather devastating to come bounding home with a new SDXC card, only to find out your device won’t take it, so check for compatibility before purchasing. The letters SDHC or SDXC should be written somewhere on the device. But if you can’t find them, refer to the instruction manual.

Decide How Much Storage You Need

Decide How Much Storage You Need

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:

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

For videos (if video is in full HD), you’re going to need:
  • 2 GB – about 20 minutes
  • 32 GB – about 5 hours
  • 64 GB – about 10 hours

For music, you’re going to need:
  • 2 GB – about 510 songs
  • 32 GB – about 8,200 songs
  • 64 GB – about 16,400 songs

By the way, smartphone apps will take up anywhere between 100 MB to 2 GB. A movie will eat up at least 1 GB. If you only take photographs, 32 GB is more than enough; however–let’s be real–we expect way more from our smartphones. 64 GB is your safest bet.

Choose Larger Capacities for More Advanced Devices

Choose Larger Capacities for More Advanced Devices

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.

If you’re shopping around for your Nintendo Switch, for example, you’ll need to know how much space software updates and apps take up. Then, figure out how many games you intend on playing, and just how much extra storage you’ll need for save files and checkpoints.
Choose Larger Capacities for More Advanced Devices
Final verdict? Most gamers will probably need 128 GB or more. If you like to take pictures and videos in high resolution, and don’t bother uploading them onto your computer, you definitely will need something larger than 64 GB.

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.

Confirm the Speed Class to Prevent Lag

Confirm the Speed Class to Prevent Lag
Let’s say you’ve just filmed a basketball game. You’re re-watching the footage, and it’s looking a little bit funny with small “stop and go” frames in it. That’s because the data wasn’t written fast enough to keep up with the players’ movements. When you’re sending data from your smartphone to the micro SD card, you want faster transfer speeds.

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.

Check for Temperature- and Water-Resistance

Check for Temperature- and Water-Resistance
Ever drop your camera in a puddle, or your smartphone in the toilet? Butterfingers, take heart: your data will remain as long as the micro SD card is fine. If you want to play it safe, you should opt for a waterproof SD card, along with a waterproof smartphone.
If you’ve got a dashcam or outdoor security camera, you may worry about heat and cold resistance. Luckily, SD cards are made to withstand both the heat and cold, with most of them surviving between -25℃ to 85℃ (when in use) and -40℃ to 85℃ (when not in use). There won’t be much difference between different brands, as long as they are consumer grade/commercial grade.
