Win7 Ultimate expansion of hard drive capacity needs to pay attention to what issues

1, in fact, as long as the computer purchase time is not very long, then the space that needs to be expanded will not be very large, maybe it is so many dozens of G, if this is the case, small I suggest you spend more than a dozen dollars to buy a second-hand hard drive. As for the latest ITB hard drive, there is not much need. Of course, if the demand for space is large, it is another matter.
2, many people think that the harder the hard disk space, the faster the system runs, of course, this argument has some truth. But at the same time, the space becomes larger, and the more time it takes for the computer to self-test, the more it will affect the speed of the computer.
3, pay attention to set the hard disk priority to start, otherwise, it may cause the computer can not boot properly.
4, the expansion of the hard disk is best with its own hard drive model, the same brand, otherwise it may be a problem.
