What Is a Micro SD Card?

MicroSD is the smallest variation of a Secure Digital standard for memory cards. To put it simply, this is a small chip encased in a plastic body that serves as data storage for your files just like a hard drive on any computer or notebook. A lot of phones and tablets come with a special microSD slot to increase their memory. In modern video and photo cameras, these cards serve as the only storage for your videos or photos.

All of the microSD cards have exactly the same dimensions but may come in a variety of memory size. According to the engineers' forecasts, the maximum possible capacity for an SD chip is 2 TB. But manufacturers are yet to create such card. That's why we are left with a market filled with cards of a memory capacity ranging from a few MB up to over hundreds of GB.

We tried to make an easy-to-understand guide and a quick review of 5 different microSD cards so that anyone could sort out, what unique features they have.

And if you are looking for a really large storage for your information, take a look at our picks of the best portable hard drives, external SSDs, and external hard drives. Finally, you might need to get a memory card reader to work with many microSD cards. Yes, we've already prepared a nice review of them for you as well.

What Features to Compare

First of all, we want to note that the following info is fully applicable to all SD and macroSD cards as well.

In most cases, consider your budget and go for the highest Memory Capacity available. However, this approach has a large pitfall, because not every microSD card is compatible with every device. All microSD cards have exactly the same dimensions, so there is no other way to check the Compatibility with Card's Format, except to look through the characteristics of your device and compare them with the tags, written on a card. They may have the following marks:

  • SD – Secure Digital cards with a capacity from 1 MB up to 4 GB.
  • SDHC – High Capacity cards from 2 GB up to 32 GB are marked with it.
  • SDXC – eXtended Capacity for bigger than 32 GB cards. These have the largest amount of memory available. 

The next compatibility parameter to look for is Speed Class. It refers to minimum data writing rate. Luckily, you can find the speed class marks directly on a card as well. Let’s skip the Class 2 as it became almost obsolete and take a closer look at the classes, that you may come across way more often:

  • Class 4 and Class 6 cards have 4 and 6 MB/s minimum writing speed accordingly. That’s the slowest for video recording in HD quality.
  • Class 10 has a minimum writing speed at 10 MB/s and maximum reading speed at 25 MB/s. It is enough for recording video in HD 1080p quality. Although it might not work fast enough with modern phone or tablet.
  • U1 class has a minimum writing speed at 10 MB/s as well, but the reading speed can reach up to striking 104 MB/s, because they are built with a different technology called UHS (Ultra Hight Speed bus for data transferring).
  • U3 class boasts 30 MB/s minimum speed and support recording video at 4K! The reading speed here can be up to 312 MB/s.

N.b. the U1 and U3 classes cards are compatible with Class 10 devices, but they will act at a speed of Class 10 card then. As a result, you might find Class 10 tag along with U1 or U3 at the same time.

Both SDHC and SDXC card formats can come with additional labels - UHS-I, UHS-II or just I and II Roman figures. Those refer to the UHS bus speed of the card, that in turn provide quicker reading and writing. The II cards are preferred, as they are faster, but again, not all devices are compatible with them.

In simple words, the closer to the bottom the better. Classes 4 and 6 are okay for most of the devices that don’t require super-fast data transferring speed: e-book readers, portable mp3 players, and mobile phones with up to 720p video recording. As for DSLR, P&S cameras or phones with video recording at up to 1080p, we recommend either Class 10 or U1 card with I or II Roman figure on it. For the professional camcorders or top-of-the-range DSLRs cameras, you might want to consider the U3 card with either I or II tag on it.

Never forget to check out Extra Features. As a rule, all of the microSD cards are supplied with SD adaptor. Water-resistant qualities would be welcomed if you love extreme sports. Furthermore, some manufacturers provide free software for data protection, creating backups or even restoring deleted information together with their cards. Finally, the long-term warranty is always appreciated. 

In this review, we've picked up 5 different microSD cards for you to find out the best one for your device. Please, remember: you can find the very same models with different storage capacity.

Samsung MB-ME128GA

Another One From Samsung

Samsung is one of the biggest conglomerates in the world. And while they are known in South Korea for their involvement in virtually every part of the market, ranging from life insurance to real estate, the Western world is more familiar with their brand thanks to their publicly traded consumer electronics subsidiary known as Samsung Electronics. And rightly so, given that this particular subsidiary also happens to be the second largest information technology company by revenue in the entire world. Whether you wish to purchase a semiconductor for your desktop, a refrigerator for your kitchen or a flat-panel television to enjoy your favorite TV show, you can rest assured knowing that there is a quality Samsung product waiting for you online or in your nearest electronics supermarket. Naturally, such seemingly small yet nonetheless important item as an SD card is also being produced under the Samsung brand.

Amplim 64G UHS-1

Ample Opportunity

When it comes to electronics in general and information technology equipment in particular, there are some companies that have a lot of notoriety in virtually every share of the market. Then, there are some that do not branch out but could boast a considerable amount of popularity when it comes to a specific part of the market such as microprocessors or smartphone screens. But, of course, just like in any other business, there are companies that haven't been able to accrue a considerable amount of reputation due to being new to the scene or some ineffective advertising methods. Due to this very reason, these kinds of companies tend to be overlooked by the public and their often exceptional products may fly under the radar of consumers. Amplim could certainly be described as one of those firms. Based in a small town of Menlo Park, California, Amplim is a company that specializes mostly in mobile phone's equipment but hasn't been able to become a name brand in this particular field just yet. And that is quite a shame since the Amplim 64G UHS-1, their newest microSD card, seems like a kind of product you wouldn't want to miss.

Review of Amplim 64G UHS-1

Looking to film your son's entire soccer practice but afraid you will run out of memory?

With Amplim 64G UHS-1 you won't have to worry about any of that. The aforementioned memory card is of Secure Digital eXtended Capacity format and with 64GBs of space under your belt, you will never have to worry about being unable to capture an important moment of your life due to running out of space.

With a price like that, some may think that the developers are definitely going to skimp on something like reading or writing speed. Well, these people are going to be in for quite a surprise. This microSDXC card utilizes UHS-I technology for up to 600x (90MB/s) Read Speed on UHS-I enabled host devices. It also supports Class 10 for 1080p full-HD video recording and playback.

SanDisk SDSQUNB-064G-AZFMN

A Memory Card Veteran

Some people are adventurous by their very nature. Obviously, we all like to travel and only a minuscule portion of our population tend not to get particularly excited about new things and experiences. That feeling of finding out your new favorite restaurant or your now preferred line of clothes is a kind that very few could rival. But there are some things that those of us who are less audacious prefer to be in a more constant state. Stability, especially when it comes to information technology, is something that is generally perceived as a sign of quality and success. And there isn't a better example of that than SanDisk in the world of storage devices. After all, they were one of the three companies beside Panasonic and Toshiba that introduced the Secure Digital format as an improvement over MultiMediaCards that has become an industry standard over the years. The aforementioned companies formed SD-3C, LLC, a company that licenses and enforces intellectual property rights associated with SD memory cards and SD host and ancillary products.

A veteran in the industry of storage devices in general and memory cards in particular, SanDisk is usually the one people look out for when they are in need of a new flash memory product. And the newest addition to their family by the slightly complicated name of the SanDisk SDSQUNB-064G-AZFMN is another great example as to why people prefer to put their trust in them when it comes to memory cards.

Transcend TS16G

A Storage Device

There's been a noticeable trend in the world of technology towards making the devices multifunctional and all-purpose. Your phone is now a camera, your camera is a phone, your refrigerator has a TV built into it, and to top it all of, every piece of technology is also a computer whether you like it or not. And it's not like there's anything necessarily wrong with that. Very few of us do not enjoy having a phone additionally serving as a portable computer, a camera, a reading device and an entertainment center with internet access that is the size of a wallet comfortably sitting in our pocket. But sometimes, all of these additional functions and features can prove to be a bit of an overkill. At the end of the day, what you want from your device is simply to serve its' primary function and the rest is optional. The Transcend TS16G is exactly that. What you get when you purchase this memory card is a storage device that does its job and isn't bloated with unnecessary features that only get in the way of the primary purpose.

Review of Transcend TS16G

Each 64GB card can store a full 28 hours of Full HD video or over 16,000 of your favorite mp3 tracks – all in the palm of your hand. When paired with a high-end card reader, such as the Transcend's USB 3.0 TS-RDF5, transferring files between card and computer will seem almost instantaneous and seamless. To help increase long-term reliability, the memory cards are equipped with built-in ECC which automatically detects and corrects any potential transfer errors.
