I have three of these and carry all on my key chain. Some people feel this is foolish, but it is important to me to always have my flash drives and not discover the one I need was left at home. Drives with plastic cases and moveable parts break. Plastic key ring holes break. This jump drive is all metal and has no moving parts. The oldest one I have has not failed in more than a year of use. If you want a flash drive on your keychain, this is the one.
My systems allows me to use USB drive to play the music I use for car shows. This size allows me to have as many folders and as many as 4000 mp3 per flash drive.
