The av­er­age Nikon now has a res­o­lu­tion of 24 mil­lion pix­els, mean­ing that a 32GB card will hold an av­er­age of 1500 RAW and JPEG files com­bined. SD cards are clas­si­fied by class. For UHS cards, look for the num­ber sur­rounded by a U shape; ‘1’ de­notes a min­i­mum speed of 10MB per sec­ond and ‘3’ of 30MB per sec­ond. There are sev­eral SD card types avail­able, so check which is most com­pat­i­ble with your cam­era. At present the high­est per­for­mance for the majority of the Nikon range is UHS-1. When you buy a pre­mium card check for fea­tures such as mag­net-, shock-, tem­per­a­ture- and wa­ter­proof­ing. The speed quoted isn’t al­ways what it seems. Check that write speed (writ­ing data to the card) is as im­pres­sive as read speed (read­ing data off it), as this is more im­por­tant when shoot­ing.
