An SD card can be quite useful if you are trying to increase the storage space of your digital devices. But not all SD cards are equal. They vary in speed classes, physical sizes as well as storage capacities.

So when you are going to buy an SD card, you need to be very careful about having a look at all these criteria.

you do know, that there are different digital devices and they use different kinds of SD cards?

Here are some of the points you need to keep in mind when you are buying an SD card:


Capacity of the SD card is the essential criteria that you should look for. Different SD cards have different amounts of storage spaces. The capacity of the standard SD card can range from 1MB to 2 GB or 4 GB.

Secure Digital includes five card families available in three different sizes. The five families are the original Standard-Capacity (SDSC), the High-Capacity (SDHC), the eXtended-Capacity (SDXC), the Ultra-Capacity (SDUC) and the SDIO, which combines input/output functions with data storage.

The three form factors are the original size, the mini size, and the micro size. Electrically passive adapters allow a smaller card to fit and function in a device built for a larger card.

The SD card’s small footprint is an ideal storage medium for smaller, thinner and more portable electronic devices.

So before you spend your hard-earned money in buying an SD card, be sure to know about your capacity requirement. It’s better to think about the capacity that your smart device will be compatible with. Thus know about the compatibility of the SD card you are buying and then spend your money.

Speed Class

Not all SD cards offer the same speed class. In addition to these, different people require different speed classes of an SD card. For example, if you are a photographer and you want to take photos in succession in a DSLR camera, you will need a high-speed class SD card.

A fast SD card also helps you record videos quickly, and you can also get a high-resolution video. But if you need an SD card for your regular smartphone, an average SD card will also be fine for you.

A speed class is used by a manufacturer to measure the speed of the SD card. There are four different speed classes in SD cards, and these are speed class- 10, 6, 4, and 2. Amongst all these, the speed class 10 is the fastest.


When choosing an SD card you need to go for brands nothing more, nothing less. If you want to buy the best quality SD cards from your favorite brands like SanDisk, Samsung, etc, are the best choose.

Sandisk cards are most popular in the market right now. But it’s better to buy genuine Sandisk SD cards from the market, as numerous platforms sell fake Sandisk SD cards.

Physical Size

SD cards also come in different physical sizes. The three different sizes of an SD card include standard SD cards, Micro SD cards, and MiniSD cards.

The standard SD cards have the largest physical size, and they are mostly used for cameras. The micro SD cards are the smallest of all SD cards, and they are primarily used in mobile phones and other smart devices these days.

The mini SD cards are smaller than the standard SD cards, but these are not commonly found these days. When choosing an SD card size is one of the most essential factors that you should look for. Choose an SD card that fit well in your smart device.
