WD elements is the external hard-disk which is used for storing the days externally in the form of external hard-disk. It is very useful to portable to anywhere. But it is having less flexibility. I mean it will not with when it drops or any Misusage. We can store almost 940GB data in it. And the days transfer speed also good while transferring from laptop to this wd hard-disk. But It is in delicate condition. My best suggestion is to use it in proper way and especially don’t keep it in the any water places And don’t drop it from the hands. However wd is the best brand for external harddisk.
