Cards that will not fail on the job, readers that are faster than the card, and somewhere to put the files afterwards.
Buy the speed your camera can actually use and no more. A V90 card in a body that writes at V30 is money spent on nothing. We will check your model before selling you the expensive one.
Everything we sell is bought through the official distributor. Counterfeit cards are the single most common cause of lost work we see.
Two copies in two places, one of them not in your bag. We stock portable SSDs and desktop drives, and we will format them for your system at the counter.
