How We Chose Our Ratings

In looking at micro SD cards, we look at a variety of different aspects that might impact the performance. We cannot honestly claim to have a high-tech testing facility on site to determine of all marketing materials are true with these cards.

However, many factors that are easily analyzed can help us determine which cards might be the best ones. Among these factors including the following:

1. Pricing:

The overall pricing of small SD cards for tablets and phones has come down considerably. So we look at pricing not just for what is the cheapest, but the best bang for your buck.

2. Brand Reputation:

When it comes to SD cards, the most recognized household brands aren’t necessarily the best deals. In this market, there are many sub-brands that the average person has never heard of that make great storage cards. Some of these lesser known brands have developed a bit of an underground following of super happy customers.

3. Record of Reliability:

Does this particular SD card (and the brand who is selling it) have a good reputation for being reliable? Or does the card fail a month after you start using it?

4. Customer Ratings and Reviews:

Does this particular brand of micro SD card get good customer ratings and reviews? Are they known for good cards regardless of size? Do they have enough reviews to fully judge their quality?

5. Good Customer Support:

Does the hard drive come with the appropriate documentation? What is the company’s customer support like?

6. Add-Ons:

Does the micro SD card come with an included SD adapter that can be used to read the card from a computer or laptop?

7. Documentation:

While this is really not a high priority for us with something as simple as an SD card, having good documentation can be a plus for some manufacturers.

Remember: Our reviews are as accurate as possible at the time they are written. Technology changes so quickly nowadays that what was the newest and best today will be old news tomorrow.

Make sure that you read consumer reviews on your favorite online shopping websites to see what other customers were saying about the product.

Buyer’s Guide

Here are some important points you need to consider before choosing an SD card.

16 GB, 32 GB, 64 GB, or 128 GB?

While we looked at 128 gigabyte storage options in this article, you might still consider whether you really need that much space.

For example, you really don’t need a huge micro SD card for your Roku streaming device. In fact, you might need as little as 2 gigabytes for your Roku to run better. So make sure you check your device to see what exactly it needs. You also need to make sure your device can handle a huge micro SD card.


So, before you run out and buy a 128GB micro SD Card, you need to make sure your smart phone, tablet, or other device can handle it. Older smart phones in particular may not be able to use your new 128 gigabyte storage card. Why is this?

This has a lot to do with memory card formats: SHDC and SDXC. Originally, micro SD cards had “SDSC,” which stands for Secure Digital Standard Capacity. This could only handle 2 gigabytes, however.

SDHC stands for Secure Digital High Capacity and applies to cards that can hold 4 to 32 gigabytes.

SDXC stands for Secure Digital eXtended Capacity. This is for micro storage cards that hold 32 GB to 2 TB (terabytes).

The problem is, some smart phones and tablets can’t handle SDXC, which is the newest protocol. All 128 GB cards are SDXC. So if your smart phone cannot handle SDXC, you canot use a 128 GB storage card.

Most devices are backwards compatible, by the way, so a newer tablet or phone could handle SHDC and SDSC, but this doesn’t work vice versa with an older tablet handling the newer SDXC.

You can often search online for lists of compatible phones if you can’t find your device’s user manual.

Data Transfer Speed

Data transfer speed of the card is also an issue, and here is a list of the speeds from low to high:

  • Class 2 – 2 MB/sec (MBps)
  • Class 4 – 4 MB/sec (MBps)
  • Class 6 – 6 MB/sec (MBps)
  • Class 10 – 10 MB/sec (MBps)
  • UHS Speed Class 1

The more speed you have, the better for video recording. Once again, the faster the card is, the newer the card is, and that means you need to check your device to see if it is compatible.

Do You Need to Get a Specific Card for Certain Brands?

Some smart phones or tablet brands will tell you that you should get a certain brand of SD card. Sometimes, they will even go overboard with this recommendation and provide a “warning” if you insert a card that is not officially “approved.” This is typically the case with Amazon Fire tablets.

Here’s the thing: These brands want you to buy their brand of SD card. Or, they have a partnership with another company. While we cannot guarantee this 100 percent (in other words, we disclaim any liability for the following recommendation), your device will probably be fine using any good quality micro SD card.

SD card technology is fairly straightforward. There is no special “type” of SD card that magically works better on certain brands. However, you can lose data and have problems with your device if you choose a crappy SD card that fails easily. Therefore, it is very important that you choose a good quality card, regardless of brand. That will give you the best results.

Do You Really Need More SD Card Disk Space?

One of the reasons you may be looking for a big 128 gigabyte external SD card for your phone or tablet is the “out of space” problem.

For example, you try to install a new app on your smart phone, and you get an error message from Google Play saying you need more disk space.

Here’s the problem: You often cannot fix this problem with just an external SD card. Sometimes, the issue is that you do not have enough internal space. No matter how “stuff” much you have moved to your SD card, your internal disk space has filled up.

This is especially true if you have an older phone that has about 8 GB of internal disk space on it. This is simply not enough if you want to install a bunch of new apps.

There are a few workarounds for this, but unfortunately, they involve technical knowledge and rooting your phone. Once the phone is rooted, you can use an app like Link2SD to move your “internal” data and other app information to your SD card that normally cannot be moved.

Most people are not going to feel comfortable learning how to do this. And, you do risk “bricking” your phone (making it completely unusable) if you mess up the rooting process.

Therefore, what you may really need is not a new SD card, but a new phone or tablet.

Ultimately, we would recommend getting the most internal space on the next new smart phone or tablet that you can afford. For example, if you are thinking about getting a new Amazon Fire HD, and you have a choice between 16 GB, 32 GB, or 64 GB of internal storage, get the 64 GB if you can. If that is not feasible, still try to get 32 GB instead of 16 GB. You will run out of internal space a lot less quickly and your phone or tablet will last a long longer, even as app sizes continue to grow.
