But for those of you who prefer the convenience of a single mobile storage device, perhaps a RAID device is exactly what you have been wishing for. There’s not any denying that the utility of a simple external hard drive, particularly if you’re a really mobile worker or cannot get the web for internet storage.
External hard drives give users an extra location for information storage, and a few are capable of doing automatic copies of entire systems.
However there are two main drawbacks with traditional external hard drives: 1) distance is preset and restricted; and 2) there is only 1 surface for data storage. Secure data storage means multiple hard disks-literally layers upon layers of storage capacity. Whether you acquire a 250GB or a 3TB drive, you are locked into a fixed amount of quantity and your information storage needs must adjust to the capacity of this drive; at a world where data is growing exponentially, it should be the other way around.
Traditional external hard Drives
Traditional external hard drives also usually only have one means of connectivity, which can limit transfer speeds. Another downside is that these drives, even during file transfer, can sometimes affect the functioning of your system, which forces data transfers and large file downloads to be performed throughout non-work situations so that the computer can be optimized and running at full speed when in use-not ideal for people who favor advantage. External hard drives are also very delicate: one fall can activate immediate inaccessibility and so loss of data very quickly.
Furthermore, there is always the element of surprise with conventional drives. Most hard drives not allow you to know when a problem is imminent, leaving you no window of opportunity to salvage your data before it crashes. And lastly, the best external hard drives usually need to be remounted whenever the user wishes to get their data; maintaining the hard disk connected in any respect times hampers its performance, can lead to overheating, which over time, can deter the drive rate and expedite the onset of an accident.
