About Flashdisk

What is Flashdisk?

USB flash drive is a tool data storage type NAND flash memory with a tool that is integrated USB connector. Flash drives are usually small, lightweight, and can be written and read easily. Name of Flashdisk USB Drive, Pen Drive, Pocket Drive, or microdisk. In the flash device, embedded memory controller and data storage of a non - volatile alias will not be lost even if there is no power. Flash disks are generally small and lightweight form. So easy to take flash-where to go (portable) and have the ability to store a large amount of data (ranging from 8 Megabyte to 16 Gigabyte). In addition, the flash disk has also been supported by many operating systems (windows, linux, macintosh, etc.) and the flash does not need the install (the computer will install itself on a flash disk drivers - it applies to modern operating systems). This makes flash disk storage media to be portable. Flash is used by most users.

The core technology of flash disk is the use of flash memory. Flash memory is developing its own technology from the EPROM (which later developed into EEPROMS - now better known place where the computer bios). Flash memory itself is designed as a memory that can store data, the data can be saved and deleted data is written back easily. This makes flash disk is almost the same as the hard disk or floppy disk (as the storage media that can be written repeatedly). However, if the hard disk or floppy disk using a mechanical tool (needle-shaped) to read and write data, then use a flash disk controller (chip form), which served to read and write data on flash memory.

As a tool of technology-based flash memory, flash disk has a "life time" not be regarded a long time. In general, a flash disk only can be used as many as 50,000 to 150,000 times only (in this case the use of both read and write data). Therefore, try to minimize the clear write-in using the flash.
Microsoft Windows operating systems implement a USB flash drive as a USB Mass Storage Device, and use the device driver usbstor.sys. Because it features the Windows auto-mounting, and USB flash drive is a plug and play device, Windows will try to run it as much as possible right flash device dicolokkan into the USB socket. Windows XP and even after the Autoplay feature, which allows flash drive is accessed as a whole to determine what the contents of a USB flash drive is.
Mapping system is a computer storage media FAT32 and NTFS. Data stored in storage media, a special regulation that requires the operating system can use the same media that is different.

FAT32 is the mapping system used by Windows 97 and above, is the development of the FAT system used by DOS. Fomat flash format with FAT32 if you use multiple computer operating systems including Windows and 97/98/ME. Several types of media such as memory card must be formatted FAT so that can be read by other hardware (such as a digital camera and mobile phone).

NTFS is the mapping system used by Windows NT, XP, and Vista. NTFS has a system recovery and security better than FAT/FAT32, data compression and support. Use NTFS is more difficult than FAT/FAT32 damaged, if you only use the operating system that supports.

Flash disk usage.
Usefulness of course the flash disk as a data storage medium that is portable (easily carried to go everywhere). The use of special flash disk, among others:
1. As personal data storage media
2. As a tool to boot the computer mem -
3. On windows vista, flash disk can be used as additional memory for the system
4. As a portable music player (MP3 player)
5. As a tool for system administrators and computer engineers
