How many RAW files can a 16 GB SDHD card hold on a Nikon D3200?

How many RAW files can a 16 GB SDHD card hold on a Nikon D3200?

We can't answer that for you. RAW files vary in size. It depends on the pixel count of the sensor AND if the file is full size, compressed losslessly or lossy.

When you find the size of one RAW file, do the math, there are 1, 000 MB in every GB.

Either consult the manual and multiply up, or put the card in the camera and read the display.

If you lack camera or card, 'Enough,' is all you need to know.

Each file is 20.4MB in size and a 16 GB can store 518 photos

Far too many

Your work flow has to be that you copy all your image files to your computer at the end of each shooting day. Once the images are safely on your computer, format the card using the format feature on the camera

A handful of 4 gb cards are a much better idea.

Memory cards are NOT a storage device. They need to be formatted routinely to prevent corruption of image files you save on them temporarily.
