1. Why does my flash drive shows less capacity than listed?
-There are two main reasons why there is a discrepancy between listed capacity of the flash drive and what shows up on your computer. For example: The most likely reason that your 4GB flash drive shows up with only 393MB worth of capacity is due to the small discrepancies in algorithms and file formats by various operating systems. Also a portion of memory space is reserved for system files and data sectors for better flash drive performance.
-The second reason why your flash drive indicates less capacity on the device is due to capacity loss. When manufactured, some devices were not made to support higher capacity of flash drives. It is recommended for you to research information on the device manufacturer to verify the correct supported format and capacity.
2. What are the benefits of using a USB flash drive instead of burning files to a CD or transferring them directly to another computer?
-Necessity is the mother of invention, and USB flash drives are so popular today because they are faster, easier to use, and more convenient than almost any other method. Burning CD's takes time, and it's a permanent process. If you’re taking a project from your office to your home, and you’re going to be finished with it at the end of the week, burning a CD just for that can be wasteful. What’s more, if you make changes to the project, you have to burn a whole new CD in order to take it back to work.
-Transferring files directly from computer to computer can be sometimes be oddly complicated, and in most cases, you need them to be right next to each other. With a USB flash drive, it’s as simple as dragging and dropping your files and folders to wherever you need them.
3. What is the difference between USB flash drive and “regular” flash drive?
-A “flash drive” is a solid state drive (SSD) technology that stores data like a typical hard drive found in most PCs, but uses no moving parts. Flash drives come in many forms, including external storage devices, portable USB drives, and even as the main storage drive in some extra small laptops.
-A USB flash drive is the industry term for a very small, very portable flash drive meant for easy data storage or transfer, and which connects to a computer via a USB port. USB flash drives are so small that most of them are designed to easily attach to a key ring.
