That supplier of your hard drive can claim all kinds of things, but does it (still) perform as it should? There is only one way to find out: test. There are all kinds of programs for this, but a nice compact one especially for this purpose is IsMyHdOK. Now, running read and write tests is something that shouldn’t take extremely long to avoid putting unnecessary strain on your drive, so the program offers four tests ranging from fifteen seconds to four minutes. The test not only tells you how fast your hard drive is, but you can also compare it with others online.
