What is a Flash Disk? Flash Disk Meaning Definition and Explained

Flash Disk Meaning Explanation

(1) USB

(1) An external storage or optical disc drive that plugs into the USB port. See portable hard drive.

(2) The module is a small solid state drive that connects to a computer's USB port. The USB drive, which came out just before the year 2000, is made up of one or more flash memory chips that can store up to 2TB of data. USB drives, which used to be able to hold only eight megabytes, are becoming more and more useful as their storage sizes keep growing.

Backup, Data Transfer and Bootable

USB sticks are used to add extra storage, back up data, and move data from one computer to another. A lot of people also use them to spread business information. The drives often have names on the case, and people keep them as backups after getting rid of the vendor's files. Not only can USB files hold software, they can also be used to start up a computer. (see bootable disk).

Windows and Mac Compatible

Most USB drives are designed so that they can work with both Windows and Mac computers. This is possible with the FAT and exFAT file systems. (see FAT32 and exFAT).

Known By Many Names

A USB drive, which came out around the turn of the century, is also known as a "flash drive" and by many other names. Any mix of "USB," "flash," "key," "drive," "jump," and "stick" can be used.

Transfer Speed

If it's even stated, drive transfer speed is given in megabytes or gigabytes per second (Mbps or Gbps). Most of the time, transfer speed isn't listed because USB drives are only used for backup and data sharing, not for regular work where speed might be important. When USB drives first came out, they were rated by CD-ROMs, with each "x" representing 150KB per second. Something like a 90x drive meant 13.5 MB/sec (90 x 150KB). 

(2) A storage unit made up of flash memory chips. There are no platters or access arms on a flash disc, but the word "disk" is used because the data can be read and written to it like it were a hard drive. It pretends to be a disk storage device.

The first flash disks were housed in Type II PC Cards for expanding laptop storage. Subsequently, flash memory disks have arrived in a variety of formats, including entire hard drive replacements, memory cards for digital cameras and modules that fit on a keychain.
