Secondary Storage Structure

As we know that the Main Memory Stores the data in a Temporary Manner means all the data will be loss when the Power switched off. And all the data will be loss when the power goes switched off. So that we uses the Secondary Storage devices those are used for Storing the data in a permanently. Secondary storage devices are those devices whose memory is nonvolatile, meaning, the stored data will be intact even if the system is turned off. Here are a few things worth noting about secondary storage.

·         Secondary storage is also called auxiliary storage.

·         Secondary storage is less expensive when compared to primary memory like RAMs.

·         The speed of the secondary storage is also lesser than that of primary storage.

·         Hence, the data which is less frequently accessed is kept in the secondary storage.

·         A few examples are magnetic disks, magnetic tapes, removable thumb drives etc.

Hard disk drive performance characteristics 

Access time refers to how fast the disk or memory can locate and begin retrieving (accessing) a specific piece of information or transfer data to the CPU. A low access time indicates a fast hard drive. Access time is measured in milliseconds. A disk drive the access time includes both the head SEEK TIME and the LATENCY.

• Seek time: The seek time of a hard disk measures the amount of time required for the read/write heads to move between tracks over the surfaces of the platters
  
• Rotation latency is the average time for the sector being accessed to rotate into position under a head, after a completed seek. It is easily calculated from the spindle speed, being the time for half a rotation. A drive’s average access time is the interval between the time a request for data is made by the system and the time the data is available from the drive.
  
• BPI defines how many bits can be written onto one inch of a track on a disk surface.
  
  
• TPIThe key media recording parameters relating to density per platter are Tracks Per Inch (TPI)
