A pen drive also known as a USB flash drive is a data storage device that includes flash memory with an integrated Universal Serial Bus (USB) interface. USB flash drives are typically removable and rewritable, and physically much smaller than an optical disc. USB flash drives are often used for the same purposes for which floppy disks or CDs were used, i.e., for storage, data back-up and transfer of computer files. They are immune to electromagnetic interference and are unharmed by surface scratches (unlike CDs).
On a USB flash drive, one end of the device is fitted with a single Standard-A USB plug; some flash drives additionally offer a micro USB plug, facilitating data transfers between different devices. Inside the plastic casing is a small printed circuit board, which has some power circuitry and a small number of surface-mounted integrated circuits (ICs). Typically, one of these ICs provides an interface between the USB connector and the on board memory, while the other is the flash memory. Drives typically use the USB mass storage device class to communicate with the host.
- Jumpers and test pins – for testing during the flash drive’s manufacturing or loading code into the microprocessor.
- LEDs – indicate data transfers or data reads and writes.
- Write-protect switches – Enable or disable writing of data into memory.
- Some drives offer expandable storage via an internal memory card slot, much like a memory card reader.
Factors on which speed of pen drive depends:
Generally data transfer speed of any pen drive depends on mainly four factors:
- Age of the pendrive: Newer pendrive always performs faster than older Pendrive
- Types of files: Generally video,audio,docs etc. transfer at faster rate compared to application files.
- USB Port version: Latest version of Pendrives generally sold in market is USB 2.0 .if this type of pendrive is inserted in a comparatively old systems supporting USB port version 1.1 then transfer rate of pendrive slows down.
- Location of files: Transfer of data from one folder to another in same drive will be faster compared to transfer of data from one drive to another drive.
How to seep up your Pen drive:
Step 1: You should use NTFS in your pendrive to transfer larger data. NTFS is new technology file system which is an innovative file system designed by Microsoft to provide better data transfer system. You can do it by right clicking on your USB drive and format your drive by selecting NTFS from file system drop down bar.
Step 2: Change your pen drive policy: For changing device policy you should go to properties -> Hardware section and there you have list of the entire devices on your system. Select your Pendrive from there and click change settings. Here you can see by default Quick removal is selected,you must select better performance and click on OK button.
Step 3: Checking your Pen drive for errors/bad sectors Bad sectors are just unused block of space which you are not using of anything. It also affects in less size of pen drive. You should check your pen drive for errors or bad sectors. You can do it by going to properties>>Tools section of your pen drive and click on error- checking button.
