The History from the Floppy Drive to the USB
19 years ago floppys are still a carrier medium. The standard PCs of today dont still have a floppy discdrive anymore, and so its not possible to read-out the floppydisc. 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 half century ago, the laptops had indeed already a classical CD-ROM drive, but it took some time to have the CD writer fitted as standard in working stations. 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 place.
The data storage medium of today
The Micro SD card has the advantage that it is smaller and is used as a storage medium in digital cameras, for example. As a disc outer of such devices, it is rarely used, because not every working station has a SD cart reader. Therefore these cameras always are supplied with wire to join the device directly to the computer. 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 are massive and unwieldy. Better as this is the Memory sticks. All working stations have one or more USB slots, the stick needs little power and is easy to take in your bag. These three storage media are constantly refined and getting more and more memory 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.
