Ever since our phones started getting advanced, there has been an ever-increasing need for us to store more media content on our phones. These days, a high-end smart phone like the Galaxy S7 has the processing power to encode and decode high-quality images and videos of up to 4k resolutions. And for someone who shoots a lot of videos on their phones, it won’t take long to fill up the internal storage of the phone. This brings us to the issue of expanding our available storage via memory cards.
Some phones like the Google Nexus and Apple iPhones do not come with the option of expanding the available storage but these phones most times comes in higher storage capacity versions like 64gb and 128gb. This might be ok for some people but for others, it’s a deal breaker for them. especially those that take a lot of pictures and videos with their smartphones. its way faster to remove their memory cards from their phones and inserting it into their computers than actually connecting their phone to their computer via USB.
Most phones these days are compatible with SDHC cards which allows storage sizes of up to 32GB. Others mostly high-end smartphones can accept SDXC cards which is more recent and can allow up to 2TB of storage.
If you want to pick out a new memory card for your phone, you need to first check the highest capacity of memory cards your phone can get access to. For some phones, it can be as little as 32GB while some phones like the LG G Stylo can take as much as 2TB of expandable storage.
There are many brands of memory cards, and prices for all types vary widely. The performance also varies, and it is usually the case that cheaper cards do not do as well as more expensive ones. Premium brands such as SanDisk Ultra and Extreme, Lexar Platinum and Professional and Kingston Elite and Ultimate cards routinely out-perform budget-priced cards in tests, and it is generally a good idea to spend a little extra money and buy these more expensive types of card.
The read/write speed of your memory card can have a significant effect on your camera performance, particularly in shot-to-shot times and continuous shooting, and in the speed of transferring data to your computer. Cards from cheaper brands may also prove to be less reliable than premium brands, many of which come with lifetime guarantees.
You also need to consider the class of the card you are buying. There is four-speed class used to classify the speed of memory cards — 10, 6, 4, and 2. Class 4 and 6 are ok for use in everyday recording of high-definition videos and normal usage. Class 2 is the slowest and while its ok if you have a device that shoots standard definition videos, you will notice its slowness when you actually move files from it to your phone internal memory or your PC.
Class 10 is the fastest and suitable for FullHD videos and if you want to take continuous shots of HD videos. It’s still suitable for 4k recording but for that, you might want to get a UHS (Ultra High Speed). These UHS cards can improve your experience while recording videos cos of its fast read and write speed.
