A flash drive memory is a unit of data storage that is characterized by using flash as storage system memory technology and connect to other devices via a USB port. Thanks to its small size, resistance to impacts, scratches and dust, absence of noise, large capacity and easy handling, memory flash drive has become the storage device and data transport preferred by users, having replaced drives magnetic and optical as floppy disks, CDs and DVDs. features a memory pendrive, also called USB memory, USB, USB Keychain key, USB stick, flash drive or simply pendrive, basically uses three technologies: storage using flash memory technology: memory flash drive uses technology flash, a type of non-volatile EEPROM memory whose main advantages are high resistance to shocks and extreme temperatures, small size, high access speed, low power consumption and quiet for lack of mechanical elements. On the contrary, it presents several disadvantages such as high cost per MB, relatively low capacity and limited write cycles and erased number. USB port: memory flash drive uses a USB interface, specification that allows connecting peripherals to a computer and which also provides power. Currently the USB port has shifted to other interfaces serial or parallel and it has become the standard connector. USB MSC standard: the pendrive memory supports the communication protocol USB MSC (USB Mass Storage Device Class, USB mass storage device), which provides an interface for storage units are connected to the computer or other devices via USB, so that the operating system treats memory pendrive as if outside a hard, being able to read and write simply by connecting it to the USB port, without need for drivers. Uses a flash drive memory has numerous applications, as a backup, transport of personal files, music and encodingm storage, marketing with promotional purposes, secure data storage encrypted, management systems, implementation of application or an operating system.
Tips for use see some tips about how to use a flash drive memory: despite the resistance of memory pendrive, avoid shocks, falls, humidity, magnetic fields, dust and extreme heat. Before removing the memory flash drive from the USB port is suitable to communicate it to the operating system (dismount volume on Linux, on Windows safely remove hardware or eject in Mac), since sometimes data is not written at the time but through a write cache, by what if unit is withdrawn before the system save the contents of the cache data may be lost or even damage the device. It is convenient to disable autorun (autorun) feature in Windows to prevent memory pendrive from starting a specific file automatically when inserting it, in order to hinder the spread of viruses and Trojans that leverage this starting System.
