A:AnswerI’m not sure how many photos the SanDisk will hold, but I purchased a couple 256 GB SanDisk flash Drives. I haven’t even filled up the first one. But, I don’t have that many photos. You might have to purchase multiple flash drives to store that many photos. Maybe contact their customer service to ask for their recommendations.
