The Advantages Of USB Flash Drives 

A USB flash drive [also called a thumb drive] is a NAND type flash memory. NAND type flash memory was designed for the exchange and saving of data as an alternative to magnetic disks.

NAND type flash memory has the capacity to hold large volumes of data. Writing and erasing speed is also fast. On the other hand, random access is rather slow because it uses block as a unit for the purpose of writing and reading.

A USB drive is made up of a secure case small circuit board and is integrated with a universal serial bus (USB) connector. The secure case is typically made up of rubber or metal. This secure case protects the circuit board of the USB drive from damage. USB drives are very much smaller than floppy disks and are rewritable.

A USB drive can be easily inserted into the USB port of a computer. With the help of USB flash drive, data can be safely and easily transferred. A USB drive is more reliable and safer than a floppy disk. USB drives are small and compact, so users can carry them easily in their pockets or they can attach it with their key chains as well.

USB drives are more reliable when huge amounts of data have to be moved. Some USB drives allow 1 million erase or write cycles. The USB Memory card readers have a removable flash memory card. USB flash drives provide more benefits to users than other storage devices.

 USB 2.0 is much faster than an optical disk in terms of the data storage in a much smaller space. The name "drive" is given to the USB flash drive because the USB flash appears to the OS of the computer as a mechanical drive and the method of access is also the same.

The USB connector must be protected and kept safe using a removable cap or by retracting the USB connector into the body of the USB flash drive. The USB flash drives use all the power supply

The reason that USB drives became popular is that floppy drives frequently fail to read data from the floppy disk. Users had problems while transferring data using floppy disks. USB flash drives do not have movable parts like floppy disks had.

There have been a number of wonderful inventions during the 20th and 21st century. Some of these creations have been both massive and minute. Very few of mankind's modern creations have revolutionized working life so much as the USB flash drive, though. Ok, that might seem a bit much for some people but the reality remains the same - USB flash drives have made the working lives of millions of office workers, teachers, students, IT and other professionals massively more simple. If you already own one (or a few) USB flash drives then you'll know just how incredibly useful they are. If you don't already own at least one USB memory stick then hopefully this article will help convince you of their absolute usefulness in both your working and personal life.

What's so great about USB flash drives?

Prior to the creation of USB flash drives all external storage devices for computers were either bulky or awkward (dozens of blank discs for example) or sometimes an annoying combination of being both bulky and awkward. USB flash drives are also called Thumb Drives because they're about the size of your thumb (although some are much smaller now) and you can easily fit several gigabytes of data in your jeans or shirt pocket, thus eliminating the bulky and awkward factor straight away.

Portable

USB flash drives are about the single most portable data backup device possible. They don't require an external power source of any kind, nor do you need any cables or tools to set them up and last but not least they don't require any additional software to be installed for them to work on any modern computer (Windows XP, 2000 and Vista and most Macs) so you can quite literally pick them up and use them anywhere you want.

Reliable

Once the data is stored on a USB flash drive you can rest assured that it's going to stay there and be there when you next need it. This is totally unlike the world of floppy disks or rewriteable CD/DVD discs where they can just stop working for no apparent reason. Flash drives were built to provide consistent and reliable performance. Most of these drives come with built-in write protection to prevent you from overwriting your own important data - if you were silly enough to do so.

Tough

For years people fiddled with boxes of floppy disks and CDs/DVDs. These were bulky, easily lost and easily damaged. External hard drives also provided another method of transporting data between systems but the smallest jolt was and is enough to kill an external hard disk stone dead. USB flash drives are based on what's called Solid State Memory - this simply means that it's the same as standard computer memory in that it has no moving parts and is therefore almost impossible to damage (except for jumping up and down on it or maybe hitting it with a hammer for example. Please don't test either of these theories at home!)

Mass Storage

The first USB thumb drives only offered between 16MB and 64MB of storage space. The incredible popularity of these drives has driven the desire for more and more storage space to new heights every few months. Currently 8GB USB drives are becoming pretty common and it won't be long before the 12GB and 24GB models hit the market. To put this in perspective 8GB is enough to hold 2 full DVD quality movies or about 2,700 high quality MP3 files - surely this is enough for you? No?

The portability of the USB flash drive combined with reliability and the more than generous storage provided by such a tiny device make them the smart choice for anyone who needs to move files between PCs or simply just keep a second copy of their most precious data on a secure and reliable storage device.
