SD cards are essential accessories for mobile phones, tablets, camcorders, digital cameras, and many other gadgets that have a memory card slot. They also offer a secure and affordable way to expand the memory capacity of any laptop since most modern day laptops come with an SD card slot.
And since some of these cards come with high storage capacity to the tune of 512GB, are portable and some even waterproof, they are more preferred to the other bulky storage alternatives. Yes, you heard that right, waterproof SD cards exist, and we’ll cover that shortly.
When buying SD cards, it’s very important to consider the speed and capacity. A class 6’ memory card is capable of writing at 6MB/S which is sequential for writing large amounts of data. Most devices that record HD video require 10MB/S and this is where the UHS (Ultra High Speed) SD cards come in.
But in order to benefit from such high speeds, you’ll need a device that is compatible with the UHS standard. Some of these high-end SD cards come with other premium features and are also waterproof. In this roundup, we will highlight the best waterproof SD cards.
