When you go to the store to buy an USB stick the storage capacities of sticks are much larger than those you would find in the same store 10 years ago. However, the physical size of today’s USB sticks is about the same (or even smaller) as the sticks from 10 years ago. How?
In: Technology
They have explained how semiconductor has advanced and you can store more in a small space but that is not the primary facto for a USB drive size. Just compare USB drives to Micros SD cards.
The size of a USB stick is the primary one that is simple to handle and easy to make.
There are smaller dives like the [Samsung Fit Plus](https://www.androidcentral.com/sites/androidcentral.com/files/styles/large/public/article_images/2020/04/samsung-fit-plus.jpg) that exists up to 256 GB or a [Sandisk Cruiser Fit](https://images.mymemory.co.uk/resize/ZT0xMjA5NjAwJmg9NTAwJnE9NzUmdD1vdXRib3VuZCZ1cmw9aHR0cHMlM0ElMkYlMkZzdGF0aWMubXltZW1vcnkuY28udWslMkZtZWRpYSUyRmNhdGFsb2clMkZwcm9kdWN0JTJGNiUyRjQlMkY2NDkyMjQtNC5qcGcmdz01MDA=/) that exist as a 64 GB drive. They are quite small, you will away be limited by the size of the USB connector and something to hold on to remove it from the computer.
But the start to be impractical small and smile to loose too for most application the commonly used size is the more practical option.
I think something like a [Kingston DataTraveler Kyson](https://media.kingston.com/kingston/key-features/ktc-keyfeatures-usb-dtkn-2-lg.jpg) that is longer but has the same size as the USB port is a good compromise to make it easy to hand and at the same time thinner than most other drives.
A very small drive will cost more to manufacture so a bit larger with a simple circuit board of commonly used components make the manufacturing simple with equipment that make other elections devices.
