Hello Friends
Today I am telling you about Hard Disk Drive. Hard Disk is a Non-volatile memory means Hard Disk sore your data, information permanently. In these days their are two types of hard disk IDE Hard Disk(Integrated Device Electronic) and SATA Hard Disk Drive.(Serial Advance Technology Attachment). IDE Hard Disk have 40 pin cable and SATA Hard Disk have only single pin cable, both Hard Disk are used for permanently data storage. But IDE Hard Disk working is very slow and SATA Hard Disk working is fast. Hard Disk is a space where we store our Operating System, Boot Files, Software, Records, Data, Information, Songs, Pictures, Movies and many more things. Friends whenever you buy a new Hard Disk Drive always notice Hard Disk RPM speed(Round Per Minute or Rotation Per Minutes). Hard Disk Drive speed depends on RPM. If RPM is high then your Hard Disk perform data quickly and smoothly and if your Hard Disk RPM is low then your Hard Disk perform data slowly. So Friends always choose high RPM Hard Disk. Thank You
