TODAY'S USB Flash Drives SPECIAL DEALS

What is a USB Flash Drive?

A USB flash drive consists of a flash memory storage device integrated with USB (Universal Serial Bus) 1.1 or 2.0 interfaces.  USB flash drives are typically removable and rewritable, and physically much smaller than a floppy disk.
USB flash drives are often used for the same purposes as floppy disks were. They are smaller, faster, have thousands of times more capacity, and are more durable and reliable because of their lack of moving parts. Until approximately 2005, most desktop and laptop computers were supplied with floppy disk drives, but most recent equipment has abandoned floppy disk drives in favor of USB ports.

What are USB Flash Drives used for?

The most common use of flash drives is to transport and store personal files such as documents, pictures and videos.  Flash drives are particularly popular among system and network administrators, who load them with configuration information and software used for system maintenance, troubleshooting, and recovery.

Do USB Flash Drives have a write-protect switch?

Most USB flash drives do not include a write-protect mechanism, although some have a switch on the housing of the drive itself to keep the host computer from writing or modifying data on the drive. Write-protection makes a device suitable for repairing virus-contaminated host computers without risk of infecting the USB flash drive itself.

Does a USB Drive need a battery?

Most USB flash drives draw their power from the USB connection, and do not require a battery.

What capacities are USB Flash Drives available in?

USB Flash Drives come in many different sizes.  Storage capacities in 2010 can be as large as 256GB with steady improvements in size and price per capacity expected.

How long will my USB Flash Drive retain information?

USB Flash Drives allow reading, writing, and erasing of data, with some allowing 1 million write/erase cycles in each cell of memory: if 100 uses per day, 1 million cycles could span 10,000 days or over 27 years.  Most USB Flash Drives have a 10-year data retention cycle.
