Learn more about the tiniest of data backup devices – Flash memories
One different type of external hard disk for backup is very useful for backup, but it is not a hard drive in the way we use to know it. It is a hard drive that is quick yet quiet and without moving parts. It is an external hard drive that is easy to disconnect and carry around. It is what is called a flash memory device or you may have heard it with other names such as a memory stick, pen drive, SD card, or memory card. But the flash memory device is basically a unit memory unit that is capable of transfer rates of up to 18 GB per hour and has the benefit to be non-volatile, unsusceptible to magnetic interference, lightweight, and compact. It never the less has a very real security problem for some type of businesses. There are several options for making backup on a PC to recover data. You can backup on external hard drives, PC tape backup utility, DVD-RW and online. But memory flash is the most easy and convenient to use memory gadget there is.
There are flash memory drives in several different shapes but the device most in use is a memory clip with a cap that protect the USB port when it is not in use, which is so tiny to fit in a pocket. The stored data doesn’t vanish, when you disconnect the memory drive from the computer. The flash memory uses a chip technology based on further development of the old EEPROM chips technology. The BIOS firmware in PCs use EEPROM data chips when computers boot up.
Data transfer to the flash drive is slower than with the more common hard disk drives but much quicker than with DVD or CD. These tiny data devices are great for doing quick backups of folders on your laptop or PC at work so that you can transport the information to another PC because the “drive” usually just fits in your pocket.
The convenience the flash drives offer with its small size and mobility has a weakness. One drawback is that it is easy to forget about and if it remains inside a pocket in your clothes which has been washed in a washing machine, it’s lost (although, in some occasions if you dry your clothes, they have been known to still be working). The mini size makes it also easy to lose track of when you are searching for a change and need to pay for something.
A dilemma that many companies have is with security of information with these types of data devices. Just picture how easy it is to store sensitive personal data information on a flash memory device only to have it lost and in the possession of a wrong person. This is the reason that, many departments have policies prohibiting general employees from bringing in personal flash drives for use on company computers.
One extra plus from having flash devices is that support technicians are capable to store the operating system such as Windows XP on a flash drive. This memory drive then be kept as an extra startup drive for the Windows computer if the hard disk refuse to boot. An essential thing to investigate is that not every PC can use an USB data device as a startup device for the BIOS by setting it as a primary startup drive. Some PC’s lack the support for using the USB drive as a primary boot drive ,which you have to check out.
