    This depends on how many channels you use, if you use several dozen of apps, up to 100+ then a 32Gb to 64GB Micro SD Card is recommended. If you’re a casual user which uses less than 30 channels then a 16Gb to 32Gb Card will be enough for you.

    What is UHS-1?

    UHS-I is an abbreviation for “Ultra High Speed – Class I.” It is a standard that specifies the highest bus transfer speed in megabytes per second. UHS cards are designed to provide quicker writing and reading rates, more data space on the same size card, and far more reliability than non-UHS storage devices. UHS-II is the fastest possible standard (as of 2022).

    What is UHS-2?

    UHS-II is JEITA’s next version of high-performance SD card storage, built to operate with newer devices and host systems. It was launched in 2009 as the second generation of UHS-I cards produced earlier that year. Initially exclusively accessible on microSDHC memory cards, it became accessible on SDHC cards in 2013.


    Many people are concerned about compatibility; however, if you choose one of the alternatives we’ve offered in this post, you shouldn’t have to worry about it because they’ve all been tested and proved to work with this camera.

    The only compatibility issue that may arise is the Roku max sd card size; the recommended size is 128GB, however, some users have reported working with 256GB; we tested and it worked for us as well; if you want to take a chance, go with the higher sizes; otherwise, we’d suggest staying with or under 128Gb.

    What is SDHC?

    SDHC stands for Secure Digital High Capacity and refers to an older memory stick technology that was launched in 2006 as part of a cooperative effort by Panasonic Corporation and SanDisk Corporation. SDHC cards are preformatted and ready to use, requiring no extra formatting or reformatting.
