How a harddisk performs with reallocated sectors

I want to ask how a hard disk will perform with reallocated sectors compared with 0 reallocated sectors if anyone knows, my hard disk has 1200 reallocated sectors and they have not been growing so my question in general is if the reallocated sectors may
impact the read and write speed I'm curious because theoretically I understand that the reallocated sectors are no longer used by the hard disk so the harddisk should write data on a new surface so I don't understand why performance should reduce unless the
reallocated sectors increase daily of which my hard disc i used formatting tool to write Zeros and ones to permanently erase everything beyond recovery so I'm certain start my hard disk is written data completely on a new surface or new sectors. Does anyone
have another opinion about a hard disk reallocated sectors and performance-related issues

 

CRYSTAL DISK INFO

Hi,

Don't worry with the third disk (only one sector reallocated is nothing), but the first has 28146 hours which is a long while...

I suggest you to use another tool : Hard Disk Sentinel , which is much better than CrystalDiskInfo !

 

What do reallocated sectors mean?

S.M.A.R.T. indepth online analysis of my old maxtor 40 gb (on the P4) says:

18% fitness
99% performance

and.......

NOTE : your hard disk has 399 reallocated sectors (this value is very large and your hard disk should be replaced). Hard disks do have spare sectors (usually from 256 up to 1024) used to replace bad ones. This remapping operation is transparent to the end user. Anyway, this can lead to degradated performances (because remapped sectors are in different places of the disk than the original ones and the head needs additional moving). If reallocated sectors grow over time, you might encounter some serious troubles. A backup of the most important data is suggested anyway.
