What does the class number mean on SDHC memory cards?

Each SD or Micro SD card has a speed rating, called a Class. Larger Class numbers correspond to a faster level of writing/recording (minimum performance) allowing files to be written to the card or recorded at a higher speed or definition (HD/4K).

What are the different classes of SDHC memory cards?

There are four different speed classes: 10 (10MB/sec read/write speed), 6 (6MB/sec), 4 (4MB/sec), and 2 (2MB/sec). Class 10 is the fastest, suitable for “full HD video recording” and “HD still consecutive recording.” Class 2 is the slowest, suitable for standard definition video recording.

What is Micro SD Class 4?

Class 4 — minimum data transfer rates of 4MB/s. Great for point-and-shoot cameras, game consoles and other devices with SDHC support. Identical in physical size to a standard microSD card, microSDHC cards are designed to comply with the SD card specification and are recognised only by microSDHC host devices.

Which class micro SD card is best?

The SD Card Association recommends UHS Speed Class 3 (U3) or higher for shooting 4K video, and V60 or above for 8K video. For full HD video, it suggests Class 10 or a Class 6 microSD card under certain circumstances. If your card’s write speed is too slow, it will drop frames and produce stuttering video.

How do I know what class my micro SD card is?

How Can You Check the Class on Your MicroSD Card?

1. Take your MicroSD card out of the device it is in.
2. Turn the card to the side that has “MicroSD” written on it.
3. Look for the “C” that has a number inside of it; it is located under “MicroSD.” The number inside the “C” represents the class of your MicroSD card.

What is a Class 6 SD card?

The SD Association devised a way to standardise the speed ratings for different cards. These are defined as ‘Speed Class’ and refer to the absolute minimum sustained write speeds. Cards can be rated as Class 2 (minimum write speed of 2MB/s), Class 4 (4MB/s), Class 6 (6MB/s) or Class 10 (10MB/s).
