Linux Flash Drive
By Betty Rims
A Linux Flash Drive is an external hardware bootable device which can be used to install Linux OS into the host controller which is generally a PC. Linux is a multi-tasking operating system which is considered to be far more sophisticated & secured than any other operating system available in the market. It can be loaded into a USB drive in order to explore its advanced features. All you need is a bootable USB drive to pack the Linux OS and then install it in your computer to be used for multi-tasking, maintenances & other data recovering purposes. You can also load only the required kernel embedded operations into the flash drive and install it across a network.
It is impossible to modify & recover the data from a live CD which has been permanently written. But by using Linux Flash Drive, this impossible task is made possible like modifying permanently written files and recovering the data as well. So, it increases the flexibility & becomes easier for the Linux users to have their required applications, configuration etc. to get stored & securely saved in a live USB as an extended storage device.
There are two major different ways to run Linux in an USB flash drive. The first is to use Linux flash disk and the second is to use a drive as a full Linux install. The first method is considered to be the better way & is widely used by the users. In order to get executed all the operations, a Linux flash drive has to maintain a minimum requirement of 1 GB flash USB such as the latest Linux based OSs: Ubuntu, Fedora need 1 GB of free storage so that it can be run and made changes in a live USB.
The following are the advantages and disadvantages for Linux Flash Drive:
It is portable & flexible as you can get all your required applications, files with you wherever & whenever you move as it is host independent as well as cross platform.
Almost all the computer systems in the World can maintain booting right from a live USB flash drive no matter it is a desktop, server or any small computer system. All you need is to hook up your Linux flash drive into your host controller and start enjoying its high end advanced features.
A Linux flash drives maintains security with hardware authentications and it also supports to share a single system among multiple users.
For the users who perform data back-ups regularly, Linux flash drive can back up your important files easily & securely. It can save you from accidental file damage without painful efforts.
It offers faster data copying than any optical devices and you can transfer your important data between remote computers without FTP utilities.
A Linux live USB can support a limited number of storage space & written data which is comparatively much lower than local hard drives.
It is typically not a good idea to store an operating system temporally in a flash drive rather than storing the system files in the main RAM of your computer.
Linux flash drive is generally for advanced users & experts as it is a little harder to install and more difficult to handle than other operating systems like Windows, Macs etc. So, it is not suited for common users.
Linux is a free and open source operating system. So most of the time Linux flash drives are illegally pirated.
As the device is small, most of the time it is reported to be misplaced and stolen. Therefore, reliability is comparatively lower and sensitive OS files are not recommended to store.
