From the Floppy to the USB Storage Stick
Friday, August 6th, 2010A longt time ago floppydiscs were still used as carrier medium. The actually PCs dont still have a floppy diskdrive any longer, and so its not possible to read-out the floppys. Plastic cards have 1.44 MB disk space. You could format them as required and to store new venues. Next was the CD-ROM.16 years ago, the standard PC had indeed already a standard CD-ROM drive, but it took some time to have the CD burner fitted as standard in PCs. 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 latest storage medium
The Micro SD card has the benefit that it is smaller and is used as a storage medium in digital cameras, for example. As a disc outside of such devices, it is rarely used, because not every laptop has a Micro SD card slot. Therefore these digital camera always are supplied with cable to join the device directly to the PC. The external drive has big memory space, the current ones have 1000 GB, or 1 TB in size. However, most need an external own power source, they ar heavy and unwieldy. Better as this is the USB stick. All standard PCs have one or more USB slots, the stick needs little power and is easy to take in your pocket. These three 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 disk with 500 GB for about 100 . Nowadays they are twice as large for the same price.
