A USB flash drive is a plug-and-play portable storage device that uses flash memory and is tiny enough to hang from a keychain. Its also known as a pen drive USB stick or USB thumb drive. An alternative to a compact disc is a USB flash drive. The computers operating system OS recognizes the flash memory device when it is plugged into a USB port as a detachable drive and gives it a drive letter.
A USB flash drive may be used to launch an operating system from a bootable USB, store crucial files and data backups, transport preferred settings or programmers perform diagnostics to solve computer issues and more. The drives are compatible with a wide range of BIOS boot ROMs, Linux, Maces, and Microsoft Windows.
In 2000, the first USB flash drive with an 8 MB storage capacity hit the market. Depending on the manufacturer, drives now have capacities between 8 gigabytes GB and 1 terabyte (TB), with future capacity levels anticipated to reach 2 TB.
Most USB flash drives include multi-level cell MLC memory which has a 3,000–5,000 program erase cycle capacity. On the other hand some drives are built with single level cell SLC memory that can handle about 100000 writes.
USB flash drives can connect using one of three basic USB specifications: 1.0, 2.0, or 3.0. The data transfer speeds are increased with each new specification publication. In addition to these three versions there have been a number of prereleases and updates.
January 1996 saw the introduction of USB 1.0. It was offered in two variations
1.5 megabits per second Mb PS of data transfer speed is offered by USB 1.0 low-speed.
High speed USB 1.0: 12 Mb PS data transfer rate.
Version 1.1 a revision that addressed several problems in 1.0 was made available in September 1998 and gained increasing popularity.
Pros and cons of USB flash drives
There are no moving components and negligible power consumption in USB flash devices. The gadgets, whether they are covered in plastic or rubber are normally waterproof and sturdy enough to endure mechanical shocks scratches and dust.
When a USB flash drive is disconnected from a computer or when the computer is turned off while the drive is still plugged in data on the drive can be maintained for a very long time. This makes a USB flash drive practical for backup purposes or for transferring data between desktop and laptop computers.
