About the Disc and USB Flash Drive
August 6th, 2010A longt time ago floppys are still a carrier medium. The actually PCs do not even have a floppy disc any longer, and so its not possible to read-out the floppy discs. A disk space of 1.44 MB was the maximum of the disc. You could format them as required and to store new venues. Next was the CD-ROM.A half century ago, the standard PCs had indeed already a standard CD-ROM drive, but it took some time to have the CD burner fitted as standard in notebooks. Until then, there were many computer applications 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 latest storage medium
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 disk outside of such devices, it is rarely used, because not every computer has a SD cart reader. Therefore these cameras always are supplied with wire to connect the device directly to the working station. The external drive has massive storage space, the current ones have 1000 GB, or 1 TB in size. However, most need an external own power source, they are big and unwieldy. Better as this is the Memstick. All laptops have one or more USB slots, the stick needs little power and is easy to take in your bag. These 3 storage media are always refined and getting more and more storage space. The current 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 . Now they are twice as large for the same cost.
