Before we tell you how much data can fit on different capacities, it's important to note that it is necessary for a flash drive to allocate a small amount of space for its own firmware to make it operate.
It is standard for 5-10% of a drive's capacity to be reserved as unusable space. It is also standard industry practice to state a flash drive's capacity based on physical memory, not available memory.
Now that we have that out of the way, below are general capacities for 4, 8, 16, 32 and 64GB flash drives:
