A flash drive (also thumb drive, memory stick, and pen drive/pendrive) [1] [note 1] is a data storage device that includes flash memory with an integrated USB interface. A typical USB drive is removable, rewritable, and smaller than an optical disc , and usually weighs less than 30 g (1 oz).
A USB flash drive or "thumb drive", a USB-connected computer storage using semiconductor non-volatile random-access memory; A USB external drive, a hard drive fitted with a USB interface Secure Digital, a non-volatile memory card format; CompactFlash, a flash memory mass storage device; Memory Stick, a removable flash memory card format
A flash drive is a portable computer drive that uses flash memory. Flash drives are the larger memory modules consisting of a number of flash chips. A flash chip is used to read the contents of a single cell, but it can write entire block of cells. They connect to a USB port [1] and function as a folder.
Sony introduced memory stick standard in 1998. Memory stick is an integrated circuit designed to serve as a storage and transfer medium for digital data. It can store data in various form as text, graphics, digital images etc. transfer of data is possible between devices having memory stick slots. Memory sticks are available in various storage ...
The Memory Stick PRO Duo (MSPD) quickly replaced the Memory Stick Duo due to the Duo's size limitation of 128 MB and slow transfer speed. Memory Stick PRO Duos are available in all the same variants as the larger Memory Stick PRO, with and without High Speed mode, and with and without MagicGate support.
Flash-based players: These are non-mechanical solid state devices that hold digital audio files on internal flash memory, removable flash memory cards or a USB flash drive. Due to technological advances in flash memory, these originally low-capacity storage devices are now available commercially ranging up to 128 GB.
Flash memory is an electronic non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory, NOR flash and NAND flash, are named for the NOR and NAND logic gates. Both use the same cell design, consisting of floating-gate MOSFETs. They differ at the circuit level depending on ...
Uses the SCSI command set including queuing. The electrical interface makes use of differential signaling, which enables high bus speeds and robustness under noisy conditions and reduced pin count (compared to parallel bus alternatives such as UHS-I). USB flash drive: Various USB 1.1/2.0/3.0/3.1 2000/2001 1 TB+ (not to scale)
