Capacious Hard Drives

Hard drives have different characteristics, such as capacitance. As storage capacity can learn how much data is preserved. But this option is always increasing, and depends on the recording density. Its measure in bits per square inch. But the characteristics specified volume of data stored as we are accustomed to think in terms of bytes. In addition, you need to know that manufacturers are constantly juggling and equate to 1KB 1000b, while as 1KB = 1024b. So often confusion begins when formatted "disappear" several tens of gigabytes. Know that it lost 24 bytes, and your hard drive is likely OK. The second required parameter is the random access time. Because in modern hard drives now used magnetoresistive way to read and write data, the physical movement of the reading head to the desired location and drive prochitki information takes time. Typically, this parameter is measured in milliseconds and is about 10-20 ms. What it will be less value- faster response to your inquiry. The final required parameter is the linear velocity of reading and writing information. It affects how much you have to wait capacious boot game or how fast you can save the new movie.
