Benefit of Flash Drives

Portable
Flash drives are small in size. Users can attach them to a keychain or slip them in your shirt or trouser pocket. Majority of these devices are between opne or two inches. Sometimes people ask for larger size so they can be sure they have them when they carry them around.

Memory
Flash drives can carry between 4 to 64 GB sized data. They are good for users to store large files like music, pictures, and movies. 

Transfer speed
The 2.0 version of USB drives has been recorded to transfer data at a speed of 480M bytes per second. SD memory card transfers data at 312 M bytes per second. Hard-disk drive, however, transfers data only at 150M byte per second.

Compatibility
Flash device is the standard option to connect all electronic and storage devices to a computer. You will notice that laptops, notebooks, and desktops have multiple ports meant for the USB. 

Low power
Since flash devices do not have movable parts, they consume much less power compared to hard disks which need the writing and reading parts to function.

Purpose made applications
Many applications and programs are built to run directly from the USB. Software applications like image editors, games, web browsers and office software can be booted directly from flash device.
