The History from the Floppy Disc to the USB Flash Drive
13 years ago floppydiscs were still used as a storrage medium. The PCs of this time do not still have a floppy discdrive anymore, and so there are not in a position to scanned them. Plastic cards have 1.44 MB disk space. You could format them as required and to store new venues. Next was the CD-ROM.A longt time ago, the notebooks had indeed already a standard CD-ROM drive, but it took some time to have the CD burner fitted as standard in standard PC. Until then, there were many computer programmes to buy on CDs, but data storage was not possible on them. Quite at the same time then the USB sticks, SD cards and external hard drives came to the market place.
The data storage medium of today
The SD card has the benefit that it is smaller and is used as a storage medium in digital cameras, for example. As a disk outside of such devices, it is rarely used, because not every computer has a Micro SD card reader. Therefore these digital camera always are supplied with cable to connect the device directly to the laptop. The external drive has large storage space, the current ones have 1000 GB, or 1 TB in size. However, most need an external own power source, they are massive and unwieldy. Better as this is the Memstick. All standard PC have a USB connection, the stick needs little power and is easy to take in your bag. These 3 storage media are constantly refined and getting more and more memory space. The current speed of development is such that the capacity every year doubles. However not in price. A year ago you got an external hard disc drive with 500 GB for about 100 . Now they are twice as large for the same price.
