Usb Thumb Drives
USB thumb drives, memory flashes, disks or cards are different names for the same kind of data storage devices that allow the safe, easy and quick transfer and transport of data between various USB appliances, usually computers or hard drives. USB thumb drives require no power supply to support their memory and they are totally re-writable. You don’t have to restart the computer to get access to the files on the memory card: USB thumb drives are plug and play devices. The name of USB thumb drives comes from the small size of the storage devices that are usually not larger than a human thumb.
They are usually compatible with any computer platforms, but for Windows users, only the 98, NT, 2000, XP and Vista versions can be used. Besides the good parts, there are some security concerns related to the use of USB thumb drives. They can easily get infected with viruses and all sorts of malware because there is no control for the entry of such malicious programs on the storage devices if the computer they access is infected Then, a dishonest user can upload information from a computer without the system administrator’s permission. Reversal processes can be encountered too.
Anti-viruses can be uploaded on the USB thumb drives too so that they can be used on infected computers without risking the security of the servers. Normally, the operations require high speed, unless the applications that you run on them are very complex or large. For reading files such as documents or photos, USB thumb drives function at high speed. Video files could take a bit longer but it all depends on their length and format. As for the re-writing options, there are millions of cycles involved so that there is no concern for USB thumb drives from this point of view.
You can purchase USB thumb drives from any store that sells computer supplies. The prices usually vary depending on the storage features, and the most expensive can be as much as $200. 128 MB, 256 MB, 512 MB, 1 GB, 2 GB and 4 GB are the common sizes of USB thumb drives. In case you want such a disk packaged in a nice customized design, you just need to shop with companies that provided personalized memory flashes. Whether traditionally designed or customized in a very modern form, USB thumb drives preserve their functionality and practical applications.
