While selecting a MicroSD card, the most important things to consider are the reliability, the price of the SD card, the processing speed, and the warranty on the card.
In a tablet or phone, apps always store data in small pieces shattered all across the card. Therefore, a microSD card needs to be very fast in processing speed, reading, and writing chunks bits of data (normally about 4kb) in different locations. However, large media files like videos may be stored in a single piece, this is solely dependent on the app developer. Less of importance is how fast the SD card can read and write large data files compared to the 4kb versatile speed on tablets and phones still they are important. Below are 3 things you should check while selecting a SD card.
1. MicroSD Card’s Speed
Speed consideration matters so much especially for special projects. A photography project which needs RAW format savings of photographs in high-resolution requires a high speed MicroSD card for fast saving and access. If you need a direct video recording and want to save directly to the SD card, then choosing a high speed SD card is recommended. However, if you are using a consumer camera saving only few photographs, the speed may not really be considered.
MicroSD cards’ manufacturers use (speed class) to measure the speed of each SD card and these are in four variations ranging from “2-10” with intervals of 2. The speed class “2” SD cards are the slowest while the speed class “10” SD cards are the fastest. Talking about suitability, speed class 2 cards are suitable for video recording with normal definition while the speed class 10 cards are best for Full HD Video Recording. Speed class 4 and 6 are suitable for video recordings with high definition.
The question of how to know the speed class or if it has special devices for checking the speed class is no longer a problem. All SD card speed is printed on the card. There are cheap SD Cards for sale on online stores and you can also see the speed rating on the online listing. Go for your choice. Also, note that there are some SD cards with no speed classification or with 0 SD card speed classification. This cards are probably those produced before the introduction of speed rating system and needs more attention when choosing one as some of them may be slower than even a 2 speed class SD card. In summary, not all SD cards have the same speed.
2. Check The Physical Size
Different devices have different SD card slots. Selecting a miniSD card or a standard SD card in place of a MicroSD card could be the worse choice ever.
MicroSD cards appear the smallest sizes of all SD cards with measurement of 15x11x1 mm and weighs as low as 0.25 gms. Majorly, they are used on smartphones and cell phones with SD card support and/or in other devices like tablets. A MicroSD card will only fit into its matching slot. However, you can use an adapter which allows fitting MicroSD cards into larger SD card’s form to be used in an appropriate slot.
3. The MicroSD Card Capacity
Just like solid-state drives, USB Flash Drives, Hard Drives, and lots of file storage media, MicroSD cards have different storage sizes.
Selecting the best microSD card when relating with size have often become a great challenge especially for non-professionals. Much focus has been on 64GB MicroSD cards recently because they cost around $20 and even the majority are cheaper and more available when compared to their counterparts (128GB, 32GB, and 16GB).
By knowing this, check if your device supports (extended capacity) cards before making a choice of which to buy. If the 64GB MicroSD card doesn’t have extended capacity support, it’s advisable to consider the 32GB. However, if you desire to store large files and your choice is 128GB MicroSD Card, it won’t be a wrong choice but expect it to come in higher price and still with functionality just similar like the others; just higher storage space is the difference.
