How many pictures will a 320 gb hard drive hold?

Answer 1

A memory card with a capacity C will hold N images approximately, where N = (C-O)/A. O is an overhead figure, accounting for storing names of pictures and maintaining the directory structures, and A is the average size per image. The overhead figure can be ignored, as it is small compared to the totol capacity C and the variation of A. The average image size is a function of the camera's resolution and the subject depicted, and can be anything between several tens of kilobytes to several tens of megabytes. The image size varies with the subject because different subjects compress differently; a photo of a plain white wall will need less storage than that of complex structures in a flower bed, for example. Assuming an average image size of 12 MB -a pretty high value only needed with slightly over-average high-resolution cameras-, one can estimate N as 160GB * 1024MB/GB / 12 MB/image = 13,653 images. For currently available commercial cameras and an average spread of subjects, it is probably safe to say that a 160GB memory part can store at least 14,000 images. Your mileage may vary though.

Answer 2

It's tough to say specifically as each picture file size varies. At the highest quality setting, on the highest, currently available, general use How_many_pictures_can_a_1TB_hard_drive_hold, at worst your file size would be about 1MB. At 320GB you'd be able to store about 300,000 pictures.

Remember your mileage will vary. If your pictures are taken at say 'half quality' you'll double your amount to 600,000 and so on. On average though, you'll be able to store literally hundreds of thousands of pictures.

P.S. DO NOT use only one How_many_pictures_can_a_1TB_hard_drive_holdfor all of your pictures. If you do that, and you don't have a backup then your pictures are LOST FOREVER. If you're going to use one for a picture store, buy a second and make a copy. The extra 100 - 200 dollars you spend is worth not losing every picture you've ever taken.

Answer 3

Assuming an average picture is 1.5 mb, dividing 30 gb by 1.5 mb gives an average yield of about 20,000 pictures.

Answer 4

That depends on the size and quality of the images. If your photos are 10MB each, you can store a bit over 32,000 photos on a 320 GB drive.
