Hello Bobby, Please allow to inform you that the difference in the definition of one Gigabyte by Operating Systems versus all Storage device manufacturers. Operating systems use a binary system which will present a lower number of GBs than the decimal based system used by Storage Device manufacturers to define the capacity of products. This is due to the binary system representing a GBs as a higher number of actual bytes. For example: Operating systems define a 1GB as 1,073,741,824 Bytes. Storage device manufacturers define 1GB as 1,000,000,000 bytes. Also, you may research on the internet by reading tech blogs/ articles to know more about the same.

Sorry, there was a problem. Please try again later.All I wanted was a simple number, which could have been easily provided. Instead I got a technical lesson that never addressed the question, but only danced around it. I guess I won't be buying those SanDisk 256gb's I was planning on.
Sorry, there was a problem. Please try again later.After reformatting this flash unit you will have only about 232 GB of usable free storage space. The flash comes with a couple pieces of Sandisk software you can use or not. In most cases you'll be reformatting for your MAC and free space may not change because it will still contain a hidden system volume information file on it.
