Basics to remember before buying a micro SD

It is less careful if we are blind to the standards when buying an item. Likewise when we will buy a micro SD. Even though it is equipped with information about the specifications on each packaging, the terms in micro SD are generally difficult for us to understand. At least, the following things should be considered and known before buying a micro SD.

First, know the difference in the price of each product

The first thing we need to focus on is price. On the market, there are very many micro SD products in circulation, from tens of thousands to millions of rupiah per one microchip.

This price difference is generally influenced by capacity and speed class (speed of reading –  writing data ). If you already know which capacity and speed class you need, you will be faced with various brands of micro SD with various prices. As an important note, it does not mean that well-known brands or expensive products are worth buying.

Buy products with qualified specifications, but have the most friendly prices. That way, you can cut unnecessary expenses.

Standard on micro SD

Next, we will listen to the explanation of the main standard of micro SD. For those of you who already understand this part, we make sure that you will not be bothered when faced with choosing an existing product!

Difference between micro SD – SDHC – SDXC

Micro SD is divided into 3 types namely SD, SDHC, and SDXC. Capacity becomes the differentiator of the 3 types of micro SD.

Starting from the smallest is the type of micro SD which has a capacity of fewer than 2 GB. Furthermore, there is SDHC which has a capacity range from 4 GB to 32 GB. While the SDXC type is a type of memory card with storage above 64 GB. For how to choose a micro SD capacity like what suits your needs, we will explain later.

Classification of writing – reading micro SD speed

The faster writing and reading speed data of a micro SD, the better the micro SD you have. The micro SD classification based on speed classes is generally divided into two types, namely SD speed class, and UHS speed class.

UHS speed class is the standard for speed of writing-reading data created in 2010. Obviously, UHS is faster in processing data than SD speed class. Unfortunately, not all electronic devices support micro SD with UHS speeds. If this is the case, just choose the SD speed class.

SD speed class is divided into four parts according to the speed they have, namely 2, 4, 6 and 10. Usually, the product is indicated by ‘ Class 10 ′.

While the UHS currently still has only two types namely 1 and 3. Usually, this specification is indicated by the words’ U-1 ′. The larger the class number, the faster the reading of the microSD data.

Estimated maximum data transfer speed

There is one more sign of a micro SD speed class which is commonly called the maximum transfer speed. This sign is a guarantee from the manufacturer that the micro SD they make can work up to a certain speed when processing data. Usually, information about this specification is written in the format __MB / s.

How to choose a micro SD card

From basic knowledge about micro SD cards, let’s see how to choose the micro SD that is right for you. We will give you tips on choosing based on what electronic devices you will use, how much capacity you need and what micro SD endurance you need.

What electronic devices do you want to insert micro SD?

Before the micro SD, the memory card had a larger size. We usually call it the SD Card. These products are commonly used on PCs and digital cameras. However, a memory card appears with a smaller dimension, the micro SD, which is eventually used in smartphones, audio players and other electronic devices.

Choose the type of micro SD that supports to operate on your electronic device. You can check this through a manual or internet book. Do not let you buy the SDXC type, but your electronic device does not support the operation of the memory card with the super large capacity.

What is the micro SD capacity needed by a smartphone?

The next way to choose is to emphasize how much capacity you need. For simplicity, we will explain this roughly through how many images you can store in the gallery, how long the film can be on a memory card,  and how many songs can be loaded in your playlist.

With a micro SD with a capacity of 2 GB you can store 3,200 images, 32 GB = 5,400 images and 64 GB = 10,900 images. For movies, a capacity of 2 GB can be able to load 20 minutes of video, 32 GB = 5 hours video, and 64 GB = 10 hours video. For music, 2GB can store 510 songs, 32GB = 8,200 songs and 64GB = 16,400 songs. (Standard image: 14 million pixels. Film: Full HD format )

In general, micro SD will experience a reduction in storage capacity if we insert it on our electronic devices. This estimated reduction ranges from 100MB to 2GB.

If you take photos often enough, 32 gigabytes would be enough to accommodate your needs. However, for those of you who have a high performance like storing lots of videos or having data with large capacity, 64 GB is the type we recommend. Don’t forget to check the speed class micro SD before buying so you don’t experience any problems with the usage later.

Speed class with a level   high makes you ‘stress-free’

Don’t underestimate speed class on a micro SD. When you record video, it is very vulnerable to the performance of a smartphone, the camera or video recorder is interrupted because writing data on micro SD is too slow. So it is better to choose the speed class with levels in order not to stress you out later.

Speed ​​class actually shows how many MB ( megabytes ) of data can be processed by micro SD. For example Class 2, this memory can process 2MB per second, while Class 4 can process 4MB per second and so on. For UHS Speed ​​Class, U-1 can process 10MB per second and U-3 30MB per second.

There are few notes for those of you who like to take videos. For those of you who want to record video in full HD format, at least micro SD  Class 10 is needed. While the quality of the 4K video, you need micro SD with U-3 speed class.

Check whether you need micro SD waterproof  /  X-Ray resistant

Imagine if your electronic device falls, breaks, or gets wet, then your micro SD is damaged even though there is important data in it. Of course, events like this will make us very dizzy.

As a precautionary measure, it should be noted that it will be the field of microSD use. If the user is later vulnerable to wetness, choose a micro SD with waterproof specifications. For those of you who will often use a micro SD traveling through the airport, it is better to consider the procurement of micro SD with the specification of x-ray resistance. And for those of you who will use this micro SD for outdoor activities, it is wiser to consider the specifications of heat – cold weather resist.
