A USB stick is also colloquially called a memory stick, and it is the replacement for earlier floppy disks and CD-ROMs. The technology that lies behind it, is a combination of several older technologies, but with the USB stick, the cost is lower, the power consumption is less and the size is also much smaller, which was made possible with the development of microprocessors. On the other hand, there is far more storage space on a USB stick compared to the old-fashioned floppy disks and CD-ROMs. A modern USB stick likes to have a capacity of up to 32 GB, where an old-fashioned floppy disk, for comparison, could only hold 1.44 MB.
You could say that a USB stick works almost like an external hard drive, but unlike a hard drive, the USB stick plugs directly into the computer and it does not need to have connected power to work. Since it has no moving parts it is very durable and it has a very long life, the memory of most USB sticks is based on a multi-level cell that allows writing/deleting up to 10,000 times, but some USB sticks are based on a single-level cell that allows writing on it as much as 100,000 times. Data can be stored for up to 10 years on a USB stick.
The first commercial USB sticks – with a capacity of 8MB-were launched by IBM and Trek Technology in 2000. The next generation of USB sticks uses USB 2.0, but due to technical limitations, they can not fully exploit the speed of 480 Mbit / s. At the end of 2008, USB 3.0 was introduced, and again the speed was vastly improved. USB 3.0 has a transfer rate of up to 5 Gbit/sm where USB 2.0 for comparison only had 480 Mbit/s.
However, it was not until 2010 that consumer equipment was able to benefit from the increased speed.
A USB stick has many different uses. The most common is probably-in the same way as the old-fashioned floppy disks and CD-ROMs – to use them for backup and file exchange. Here the advantages of the USB stick are obvious, since, as already mentioned, it has much greater capacity and speed than the older media. The USB stick can also be used for data storage, where encryption can be used to secure sensitive data.
Certain applications can run directly from a USB stick without prior installation. In these cases, the high speed is a clear advantage: anyone who has tried to run a program directly from a CD-ROM will be really happy with USB 3.0. Similarly, certain operating systems can be installed and/or booted directly from a USB stick.
There is no doubt where the advantages of a USB stick lie, compared to other mobile storage media: the small size, the high speed, the large capacity, the long life and the easy use. It’s just plugging your USB stick into the computer, and it runs – whether you want to backup, move files, install or some of all the other uses a USB stick has.
