Internal Hard Drives – SSDs vs HDDs



Hard Disk Drive

Every computer has a pre-installed hard drive that resides inside it. This is called Internal Hard Drive. It includes the operating system and a few important pre-installed applications. When it comes to expanding the computer’s storage space, these hard drives can be upgraded.

An Internal Hard Drive is of two types – Hard Disk Drive (HDD) and Solid State Drive (SSD). A Hard Disk Drive makes use of a rotating disk in order to store and extract the data. The performance of the computer increases as the hard drive starts to spin faster. These hard drives are meant to provide large amounts of storage. Whereas a Solid State Drive provides better speed, longer life, and security but less storage capacity. It uses integrated circuit assemblies to store information persistently, using flash memory and operating as secondary storage in the hierarchy of computer memory. 

Another option to expand your computer’s storage space is connecting an External Hard Drive to it. It is a portable solution that is externally connected to a computer via USB or FireWire cable. Popular examples of External Hard Drives are CD, DVD, Memory Card, Pen-D, etc. People often tend to choose Internal over External Hard Drives because of the following reasons: 

  1. Internal hard drives are directly attached to the motherboard and hence provide a faster speed of data transfer as compared to external hard drives that are connected through USB cables.
  2. Internal hard drives reduce the hassle of keeping regular backups, and the files remain safe and available for use when the computer starts. 
  3. Internal hard drives are not exposed to dust, dirt, and risks of falling and losing. Hence, they are more secure as compared to external hard drives.

Let’s look at the differences between the types of Internal Hard Drives, i.e., a Hard Disk Drive and a Solid State Drive:

  1. One of the significant differences is that an SDD has no moving disks inside it. The drive is entirely electronic and saves the information into microchips, like flash drives. On the other hand, an HDD rotates, with an automated arm writing the required data on the drive disk in different sectors. 
  2. SSDs are more secure and less likely to fail, whereas HDDs are more prone to face damage due to more wear and tear. 
  3. SDDs tend to be more reliable than HDDs and are quite durable as well. However, both types of drives are vulnerable to the risks of sudden power cuts and electric surges.
  4. SSDs operate at a better speed than HDDs because they function to randomly access data whenever required, while in HDDs, the read/write arm is needed to reach the right sector of the rotating disk.

There are instances when people or organizations face severe data loss issues. Losing important data can be a huge deal for some, and that’s when people look for a good data recovery company. In such situations, you must be very careful as acting upon the cause yourself to retrieve your data back can make it even worse. Therefore, it is always advisable to get in touch with a renowned and reliable data recovery company for favorable results.
