HOW TO:Choose best microSD card for your Android phone.

Written by Rohit Salve
You have to be very selective when it comes to selecting the right SD card your device. As some SD card will support your Android phones or Tablet while some may not detect. Today I am going to share some tips which many of the tech savy friends out there know , when it comes to a selection of SDHC and SDXC, or a Class 10 and UHS-I Class 1.

CAPACITY OF SD CARD
When we have to select a SD card we often come across two varieties of microSD cards-

SDHC microSD cards & SDXC microSD cards.
The difference between the 2 cards are its capacity for storage.
SDHC capacity ranges from 2GB to 32GB
SDXC capacity ranges from 32GB to 2TB.
You’ll most often come across two types of microSD cards — SDHC and SDXC. The difference between the two is the range in capacities they provide.
However the number of files stored in a particular SD card can be determined by size of a particular image, mp3 or video saved in the SD card.
For example : Photo take from a high megapixel camera like 16 megapixel will have a image size of 7 mb that means 32GB card, you could store 4,500 or more photos on it. (This number would differ incase of Galaxy S7, which can shoot in RAW format, creating photos with much larger file sizes.)

Also note while purchasing a higher capacity SD card it is advisable for you to check whether you device supports high capacity SD card. This information will be mentioned on your phone broacher or can get this info online.

SPEED OF SD CARD

Other factor which you need to check while buying an micro SD card is to choose its speed to write data.
There are three primary speed classes: Class 10, UHS-1 Class 1, and UHS-1 Class 3.
-Class 10: 10MB/s; burst photos and up to 1080p video files.
-UHS-1 Class 1:10MB/s; live video and 1080p video files.
UHS-1 Class 3: 30MB/s; live video and up to 4K video files.

MicroSDHC and microSDXC cards can be any of these three classes, above mentioned are the minimum speeds and intended purposes of each class:


How to identify these SD cards?
MicroSD card type (SDHC or SDXC) and capacity (GB or TB) are directly Marked on the card. The three speed classes mentioned above have logos to signify their minimum speed.

Class 10 is the letter C with the number 10 inside.
 
-UHS-1 Class 1 letter U with a 1 inside.
 
UHS-1 Class 3 letter U with a 3 inside.
Hopefully the above guide will give you an idea of which one to buy. It’s also worth sticking to reputable brands for micro SD cards, such as SanDisk, Samsung and Kingston.
