How to Select Mobile Hard Disk
For most ordinary users, they concerned about the storage capacity more than the concern of safety performance. They will care about the data security only if the capacity has met the demand. Although capacity is an important factor we should concern, but the stable and security features are always more important in fact. And this won’t make users to care about that until some problems occurred on their mobile hard disks.
Some mobile hard disk drive manufacturers cooperate with the hard disc manufacturers. They install 3D seismic in the hard drive to determine the hard disk by supporting the work of the state. Thus supporting the hard disk will be forced to move to safe area head. Specifically, the chip can predict the working status of the hard disk, mobile hard disk, such as making copies of data, play movies, which are hard to read and write heads of the operation, the chip to work. If you do not do mobile hard disk accidentally touched off the table, the process in the fall, when the acceleration reaches a certain degree of time, the chip can be detected, and then immediately stop working so hard, and hard drive head to a safe location to avoid damage by the hard disc.
In addition, the enclosure of the mobile hard drive is also very important. Mobile hard disk enclosure not only to the role of mobile hard disk appearance, it has protection. Metal in the impact performance of the best, but the shell of this material is not perfect. First of all, this material can be deformed shell is rather poor, in the sudden severe attacks by the time the impact of the internal hard drive is still not small. In contrast plastic shell shock by the sudden deformation will produce tiny, weakened the impact, so that better protect the safety of the hard disk. Do not underestimate the small deformation of plastic materials, which can be reduced to the original impact by five times.
The second is the heat. Disadvantage of plastic is not conducive to heat loss, but this is precisely the advantages of metal. Metals are the positive conductor, heat large majority of mobile hard disk with metal case. But it is not absolute, with the hard drive technology, the temperature continued to read and write drives down a lot than before, so the plastic shell is gradually replace the metal position. Tightness of the shell is a topic that people do not often mentioned, but a well-designed mobile hard disk, the seal is forced to care about stealth design. Can ensure a good seal mobile hard disk drive cartridge in the event of an accident will not be water or other liquid pollutants harm. They use a plastic molding design. You can very well ensure the safety of mobile hard disk.
You should consider all the above requirements when purchase a good mobile hard drive. But also need regularly backup your important documents to prevent accidents from happening. And this will always save much data recovery work.
