Read Speed and Write Speeds

Beyond capacity, the reading and writing speed of a card is extremely important. Especially if you are recording 4K or even 8K videos. It is worth mentioning the actual read speed/write speeds labels on a card are not always the case. Real-world results will vary greatly depending on your device, content, and other factors.

Fast transfer speeds are essential because of all the HD, 4K, 5K, 6K and 8K videos being recorded. The fastest speed currently offers read speeds of up to 300MB/s and write speeds of 260MB/s. Before you get your card, make sure to look into the minimum speed for writing and reading.

This way you will always be ready to keep your workflow moving smoothly.

The rating of the cards is as follows: Class 2 (minimum write speed of 2MB/s), Class 4 (4MB/s), Class 6 (6MB/s), and Class 10 (10MB/s). These are the minimum speeds or the least you can expect from each class rating.
