Just ask us, and we will let you know whether your data will fit on the USB drives you are purchasing, or whether a capacity upgrade is required.

If you are planning on ordering custom branded USB drives preloaded with your data, this may be useful to keep in mind if the size of the data is close to the storage capacity of the USB Drives you are ordering.

So next time you notice the storage capacity showing up on your computer is less than what was displayed on the USB Flash Drive – do not worry, you are not actually missing any space. It shows 14.8GB when plugged into a Windows PC. Here is another example of what a 16GB USB drive shows up as when plugged into a Windows PC This is an 16GB USB Drive. Unfortunately, operating systems and RAM Manufacturers still use powers of 1024 to calculate USB drive storage, whereas USB Drive manufacturers consistently use powers of 1000. This is a term that is not used in the industry. If a power of 1024 is to be used, the accurate term to use would be gigibyte. Giga (which means 10^9) implies a power of 1000 is used. The interesting thing to note here is it is actually the USB Drive manufacturers using the accurate denomination of 1000, given the terms used for storage capacity.įor example GB stands for gigabyte. This means that the 8GB USB drive you purchased is treated by the RAM manufacturers asĨ,000,000,000 / (1024*1024*1024) = ~ 7.45 GB Instead, they choose to use denominations of 1024. Now the above situation arises because RAM manufacturers and operating systems do not use the same denominations of 1000.

This USB drive is hence labelled as an 8GB USB drive, which is what you purchased. This means the 8GB USB Flash drive you see in the image above contains 8 * 1000 * 1000 * 1000 = 8,000,000,000 bytes of space. To a USB Flash drive manufacturer, 1KB = 1000 bytes The second point requires some more explanation.

The major reason comes down to differences in the way our operating systems (such as Windows and Mac OS) use storage devices, and how USB flash drive manufacturers (as well as hard drive manufacturers, and manufacturers of other storage devices) advertise the storage capacity.

Therefore although this storage capacity is present on the USB Drive, it is not available for the user.

When your USB flash drive is formatted, some storage capacity is allocated for overhead, such as the boot data and file system.
