Why you may need a mirror hard drive
Protecting valuable business and personal data from loss is essential in today's world, and that is why every computer user needs to be familiar with the concept of the mirror hard drive. While it is more common to see mirrored hard drives in the business environment, more and more home users, especially those who run home businesses in their spare time, are beginning to understand the value of using this simple technique. In its most simple terms, when you create a mirror hard drive you are creating a copy of the hard drive. The simplest mirroring situation uses two drives with an identical storage capacity. When the mirror is set up, every file that is written to the first hard drive is also written to the second hard drive. The benefit of this setup is obvious. If one of the drives fails, the data is not lost. In the event of a drive failure, the computer owner simply buys another hard drive with the same storage capacity, installs it in the computer and rebuilds the mirror. This may sound overly technical but in fact it is not nearly as difficult as it was in the early days of computers. These days most of the popular operating systems provide some way to mirror a hard drive, and there are many tutorials and sets of instructions available on how to mirror the drives most effectively. It is of course in the world of business where the mirrored hard drive got its start, and back then it was often cost prohibitive to use a mirrored solution for any but the most critical and irreplaceable business data. That is because only a decade or so ago, storage space was incredibly expensive, with even small capacity hard drives often costing thousands of dollars. Many businesses were understandably reluctant to effectively double their outlay of money for computer storage by using mirroring, and many businesses used other types of solutions, like tape backups, to cut costs. Even today, the mirrored hard drive is not always the right solution, and it is important for every business person and computer user to carefully evaluate all the options available to keep their personal and business data safe from harm. In addition to mirroring the hard drive, it is possible to make a backup copy using a portable hard drive, a DVD burner or a CD burner to copy the most critical documents. In cases where it is not practical or desirable to install a second hard drive inside the case, using an external hard drive can be a good substitute for the safety and security of the mirrored solution.
