That floor is the specification that matters for video, because it is what prevents dropped frames and buffer stalls partway through a continuous 4K recording. A card advertised only by its peak read speed tells you nothing about whether it can hold a recording.\u003c\/p\u003e\n\n\u003ch3\u003eA1 for app performance\u003c\/h3\u003e\n\u003cp\u003eThe 64GB and larger options carry the Application Performance Class 1 (A1) rating, which specifies minimum random read and write throughput rather than sequential speed.

This is true of every manufacturer. If you need a guaranteed 30MB\/s write floor for 4K video, choose 64GB or above.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAre both cards in the pack identical?\u003c\/strong\u003e\u003cbr\u003e\nYes — same capacity, same specification, same production standard. That is the point of the pack.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWill the formatted capacity match the number on the card?\u003c\/strong\u003e\u003cbr\u003e\nIt will read slightly lower, as with all storage media. Manufacturers count 1GB as 1,000,000,000 bytes while operating systems calculate in binary, and a portion of the card is reserved for its controller and file system.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I use these in a Nintendo Switch or a Steam Deck?\u003c\/strong\u003e\u003cbr\u003e\nYes. Both accept microSD, and the 64GB and larger options meet the speed requirements for game storage comfortably.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between microSDHC and microSDXC?\u003c\/strong\u003e\u003cbr\u003e\nIt is a capacity standard, not a quality difference. SDHC covers cards up to 32GB, SDXC covers 64GB and above. Some older devices read SDHC only — worth checking if you are buying for legacy hardware.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo I need to format the card first?\u003c\/strong\u003e\u003cbr\u003e\nFormat in the device you intend to use it in, not on a computer. Cameras, dash cams and consoles each write their own file structure, and formatting in-device avoids compatibility problems later.\u003c\/p\u003e","brand":"AXYON","offers":[{"title":"8GB","offer_id":43064332222539,"sku":"AXY-MSD2PK-8","price":28.95,"currency_code":"AUD","in_stock":false},{"title":"16GB","offer_id":43064332255307,"sku":"AXY-MSD2PK-16","price":35.95,"currency_code":"AUD","in_stock":false},{"title":"32GB","offer_id":43064332288075,"sku":"AXY-MSD2PK-32","price":41.95,"currency_code":"AUD","in_stock":true},{"title":"64GB","offer_id":43064332320843,"sku":"AXY-MSD2PK-64","price":50.95,"currency_code":"AUD","in_stock":true},{"title":"128GB","offer_id":43064332353611,"sku":"AXY-MSD2PK-128","price":69.95,"currency_code":"AUD","in_stock":true},{"title":"256GB","offer_id":43064332386379,"sku":"AXY-MSD2PK-256","price":159.95,"currency_code":"AUD","in_stock":true},{"title":"512GB","offer_id":43064332419147,"sku":"AXY-MSD2PK-512","price":299.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0618\/5068\/1419\/files\/61D8h5XvbCL._AC_SL1036.jpg?v=1784467923","url":"https:\/\/axyon.com.au\/products\/axyon-pro-performance-2-pack-microsd-memory-cards-sd-adapters","provider":"AXYON","version":"1.0","type":"link"}
