These days, consumer electronics in the recording industry are producing images that are less and less compressed and at higher and higher resolutions. Thus, manufacturers of storage hardware have answered this demand by producing memory cards with some truly incredible speed characteristics. If you take a memory card that’s used for 4K video recording, you’ll find that some of the fastest ones on the market can proudly be compared to SSD drives; something unimaginable just a couple of years ago. And if you’re looking to get the fastest cards possible, only buy ones with the UHS-II classification. That moniker is something only cards that can reach 312MBps speeds possess.
