USB Flash Drive

usb flash drive or any other flash memory drive is basically an EEPROM that means Electrically Erasable Programmable Read only Memory.

usb flash memory sticks are nothing but an assembly of EEPROM, a controller with a RISC microprocessor, RAM and ROM. All of this interacts with a computer using a usb controller and connector.

Because usb sticks are EEPROM, these can hold data for as long as 10 years. As these memory modules are shock proof and dont have a volatile memory, they are good enough to sustain shock and humidity. To some extent, they often undergo casual abuse that include being ran through a washing machine, or even dropped into coffee.

UBS thumb drives normally dont require drivers. But with few old operating systems like Windows 98 and Windows 95, you need drivers that are provided by the manufacturer. Latest OS consider usb drives as usb Mass storage devices and have built in support for these drive. This means that you dont need any drivers, you just plug in the drive and start using it.

Some linux versions might recognize it but wont let you use it until you manually mount the drive. To mount the drive manually, use the command:

mount vfat (drive to mount) (directory to mount at)

For eg. mount -vfat /dev/sda1/mnt/usbdrive

Manufacturers are also coming up with systems that have bios support for usb. This means that you can boot from the small usb drive. There are different versions of operating systems coming up that can be installed on a ROM and are so small to fit a usb drive as well. Most of these OS versions are linux based, for example Damm Small linux.

usb drives are mainly used to carry personnel data. But you need to be very careful with your personnel data nowadays. You can have anything in your personnel data collection that you have forgotten, for example your bank account details or anything. try using some encryption engine to secure your data. You can use encrypted file system over the usb drive. But by doing so, you will only be able to access your drive at few computers and not every single computer. Alternatively, you can have a encryption application that can run without installation from your usb. The best would be to use biometric USB drives.
