From the Disc to the USB Flash Drive
9 years ago floppydiscs were still used as carrier medium. The actually PCs dont still have a floppy disc anymore, and are therefore not in a position to scanned them. A disk space of 1.44 MB was the maximum of the floppy drive. You could format them as required and to store new venues. Next was the CD-ROM.A half century ago, the laptops had indeed already a standard CD-ROM drive, but it took some time to have the CD burner fitted as standard in laptops. Until then, there were many 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.
The data storage medium of today
The SD card has the advantage that it is smaller and is used as a storage medium in digital cameras, for example. As a storage medium outer of such devices, it is rarely used, because not every notebook has a SD card slot. Therefore these cameras always are supplied with cable to join the device directly to the laptop. The external drive has huge storage space, the current ones have 1000 GB, or 1 TB in size. However, most need an external own power source, they ar big and unwieldy. Better as this is the Memory stick. All standard PC have one or more USB slots, the stick needs little power and is easy to carry in your bag. These 3 storage media are always refined and getting more and more storage space. The latest speed of development is such that the capacity every year doubles. Still not in price. A year ago you got an external hard drive with 500 GB for about 100 . Nowadays they are twice as large for the same cost.
