SD Card Formatter 4.0 for SD/SDHC/SDXC

This software formats all SD memory cards, SDHC memory cards and SDXC memory cards. SD Card Formatter provides quick and easy access to the full capabilities of your SD, SDHC and SDXC memory cards.

The SD Card Formatter was created specifically for memory cards using the SD/SDHC/SDXC standards. It is strongly recommended to use the SD Card Formatter instead of formatting utilities provided with operating systems that format various types of storage media. Using generic formatting utilities may result in less than optimal performance for your memory cards.

The SD/SDHC/SDXC memory cards have a "Protected Area" on the card for the SD standard's security function. The SD The SD Card Formatter does not format the "Protected Area". Please use appropriate application software or SD-compatible device that provides SD security function to format the "Protected Area" in the memory card.

SD Speed Class/UHS Speed Class/Video Speed Class

Greater Performance Choices

There are three kinds of Speed Classes, "Speed Class", "UHS Speed Class" and "Video Speed Class."


As a characteristic of flash memory, actual transfer speed varies. Variable speeds are difficult to reliably record streaming content such as video because it requires a constant writing speed. Speed Class and UHS Speed Class provide the constant speed necessary for video recording by designating a minimum writing performance so that minimum and constant speed could be achieved for camcorders, video recorders and other devices with video recording capabilities under the conditional write operation specified in the standard.

  • Speed Class is marked  with Class 2, 4, 6 and 10 (DS, HS mode), UHS Speed Classes is marked with U1 and U3 (UHS mode), Video Speed Class is marked with V6,V10,V30,V60,V90 (HS, UHS mode).

  • The latest Video Speed Class covers conventional Speed Class and UHS Speed Class and designed to optimize modern NAND memory technology for high resolution & High quality video and multi-file Recording.

  • Speed Class, UHS Speed Class and Video Speed Class has no compatibility
