hard drive

If we have to repalce the hard drive  check the manufacture website to find the hard drive compatible with you laptop. When comes to a replacement for of old hard drive there several factors that need to be weighed against each other.

  • Form factor
  • Speed
  • Capacity
  • Battery life
  • Reliabliity
  • Durability
  • Cost

The types of hard drives you can choose are three types. Magnetic hard disk will have the slowest speed but cheaper cost when it comes to size of the memory. They have large form factors and not great battery life. The durability and reliability of magnetic disk is not great compared to SSD “solid state drive”.

SSHD “solid state hybrid” provide the nearly same speed as SSD “solid state drive” when booting, launching and loading. SSHD are slightly more expensive then magnetic disk by itself. Form factor and battery life is about the same as HD “hard disk”. The SSHD and HD share the durability and reliability.

SSD “solid state drives” are the most costly when it comes to storage size. They have the smallest form factor. SSD is very efficient in thier use of battery life. When it comes to durability and reliability it is the best option.

Once a new HD is picked we need to go through the removal and installation process. For some laptops’ you have to remove the whole chassis to get to HD. Other all you to do is remove the back protective case. In both cases it may be covered by a panel that has to removed. The HD will be screwed in by several screws. Those have to be removed and the sata drive connector has to removed from the HD. Putting in the drive you have to follow the same process in reverse.
