USB Flash Drives
A USB flash drive is a compact USB flash memory drive that acts like a portable hard drive, letting you store and transport your computer data.
Flash drive or Thumb drive are plug and play devices. It does not require additional installations. Windows XP will auto detect and show the device in Windows Explorer after it is plugged into the USB port.
Of course, no one uses cassettes anymore. USB Flash drive media is great for delivering custom marketing presentations, promotional give-aways, catalogs, software distribution, and more. Thanks to its reusable format, portability, and solid state design USB Flash drives are in circulation much longer than discs and Disc Makers is your resource for blank or custom printed USB drives.
Why we name it as USB Flash Drives because the storage technology behind it is called flash memory. It’s a non-volatile memory that can store little data chunks especially when there’s no power. When the chunks need to be larger the specific flash kind is used.
USB flash drives come in all different shapes and sizes but are usually no bigger than a pack of gum. Other terms you may have heard that are synonymous with this type of device are thumb drives, pen drives, pocket drives, etc. The small size of these devices should be of concern when evaluating their use in your environment; especially from an information security perspective. They are easy to hide, can store a considerable amount of data, are simple to use, easily accessible and very affordable.
If proper steps are not taken to secure your computing environment, a USB flash drive would be an ideal means of collecting valuable information and literally pocketing it. So what steps can be taken to secure your environment against these potentially sinister little devices?
A USB drive has many advantages:
- The USB drives come encased within a tough plastic shell that protects them from dust and other kinds of damage such as scratches, unlike optical disks whose data-recording surface remains exposed to the elements.
- USB drives do not need a separate drive to be installed in the computer. They are stand-alone, independent devices that draw power from the computer itself.
- USB drives are not dependent on a particular platform. They are platform-independent and can be used with any operating system.
- These drives are quite small and a number of these can fit easily in a man’s short pocket. They are also very light in weight.
- When you insert the USB drive into the computer, you do not have to reboot the machine for it to recognise the device. You can start using it immediately.
- USB drives draw power from the computer itself. They do not need batteries to run or require an external power supply.
- USB drives are very reliable and can last for a number of years. Unlike read-only optical disks, data can be written and re-written on USB drives thousands of times without any problem.
- USB drives, as the name suggests, use the Universal Serial Bus (USB) interface to communicate with the operating system. This powerful interface allows these drives to transfer data to the computer at speeds that are about 10 times higher than those offered by a hard disk.
- Despite their small size and negligible weight, USB drives have phenomenal capacities. The commonly available drives come in sizes of 1 GB to 8 GB. There are drives manufactured by some companies which have a staggering 65 GB capacity
- A USB drive has no moving parts. It is made up of an integrated circuit and a flash memory card. There is hardly any wear and tear. Contrast this with a hard disk that has platters spinning at 7,200 RPM, with the read / write head hovering above. Because of the absence of any delicate or moving parts, a USB drive is immune to impact trauma to a large extent. It does not develop a malfunction if it is dropped to the ground.
Because there are no moving parts inside, USB drives have minimal power requirements. This makes them ideal substitutes for hard disks inside laptops.
Hard drives store data on platters coated with magnetic paint. This makes them vulnerable to strong magnetic fields which can destroy their digital data. USB drives have no magnetic parts. Instead they store data in a memory card which is totally immune to magnetic fields.
As the capacity of USB drives increases with time and prices drop, they are definitely going to pose a threat to the hard disk industry for becoming the prime data-storage devices used inside computers and laptops.
