De-fragmentation shortens or Increases the HDD's life

What is Defragmentation ?

Defragmenting hard drive is nothing but a group of files to rearrange each file that is out of place in consolidated and organize files again. Then when you need a certain file, all you need do is consult the index, take the file and use it. No need to twist around the computer looking for a particular document that was lost.

But doing it very often can wear this piece of hardware?

If you are using a normal hard disk, NO. In fact the process may even increase the life of the hard disk, since the HD’s are disks that contain the files physically. Thus in order to open, read heads should be directed to the position of the item and more fragmentation, more readers will have to move.
A normal hard drive has a seek time of about 16 ms. If a file is fragmented into 20 parts, the read heads will take approximately 320 ms to effectively carry all parts of the document.

Do not Defragment SSD !

Machines with Solid State Drives (SSD acronym in English) are increasingly present in the market. Because it uses a different technology common hard drives (flash memory in Logar magnetic disk), this type of device does not need to be defragmented ever. They work exceptionally random access operations and therefore the organization of data is not really useful for SSD’s.
With respect to the recording limit, an SSD has a life expectancy of about 10,000 scriptures. That is, a frequent defragmentation, as well as bring no benefits to this type of disc, so you better save time by avoiding it.

Note : Defragmenting has nothing to do with cleaning up of files so none of your data is lost or no file is deleted.
