SD cards and our lives
So most of us have heard of SD cards, at least at some point in our lives, be it playing handheld games or even phones. However, most of us only worry about storage space rather than the important features they have.
Storage is not everything
As I mentioned above, we cannot focus on the aspect of storage and ignore the rest. We must look at write speed, read speed, and durability ratings.
Some SD’s even specify the type of usage they are rated for. For example, I recently obtained a 4K rated 32 GB microSD. To be completely honest I won’t be filming 4K, but I know that by being rated higher than what I film it will be able to handle the strains of constant filming and snapping of RAW photos.
There are independent rating agencies that give these storage media classifications. In this case, I looked for UHS and the speed class rating. This rating designates a performance option that only some cameras have and it’s designed to support 4K Ultra HD video when you enable them. This rating can go from 1 all the way up to 10 and it is labeled with a number inside a cup if you will.
Now, let’s talk storage
Storage capacity will depend on several factors, including the type of video (resolution, length, format, and quality), type of photography (format and resolution, exposure too). The guide to follow is 10000 photos at 12 megapixels in JPEG format or 1.2 hours of 4K Ultra HD video.
Remember those scales are probably going to be on the far end of your usage, but it’s worth knowing the limit of your SD.
