SSD or HDD data storage disk: What’s the difference?

A hard drive is a hard drive, right? Not quite.

Many are buying laptop and need to make a decision by choosing between a HDD (Hard Disk Drive) and a SSD (Solid State Drive) as the most suitable data storage disk.

So what’s the best option?

There is no answer to this question because the correct answer depends on each person’s wishes and how they are evaluated according to their needs, preferences and, of course, the budget available to proceed to the specific market.

Note that most bitcoin hosting companies nowadays – at least those who are not entering the market – install SSD Disks on their servers because it is faster and might cause less troubles in case of earthquakes or server shaking.

We cite the differences between an SSD and HDD data storage disk to help you make the right choice.

The obvious difference between a HDD-mechanical hard drive and an SSD-hard disk memory permanent recording is that the first is a simple magnetic disk that stores data on magnetic rotating plates where they are read by moving Heads, while the second has no mechanical, moving parts and the data is stored in the chips.

Although laptops have been significantly upgraded in recent years, in almost all of their subsystems, mechanical hard drives have not experienced any change in their core operating technology and have not so been able to follow this Evolution. This implies that it is the subsystem responsible for 90% of cases for their slow operation.

So the SSD comes to solve the most important problem of HDD, the low operating speed. Increased performance, no matter how you look at it, is the most important reason to upgrade a personal computer using an HD, replacing it with a new SSD.


Whether it’s a PC or a Mac, the main advantages of using an SSD compared to a HDD are the impressive proliferation of computer speed and minimal power consumption. The SSD memory disk because it has no mechanical parts can and offers:

Main Advantages

  • Increased performance
  • Speed in operations, Quick start/shutdown
  • Minimum energy consumption
  • Longer battery life (due to low power consumption)
  • Does not attract heat/not warms
  • Silent Operation
  • Zero Vibrations
  • Minimize potential failure/loss of data (from vibration impact)

The main disadvantages in relation to the HDD are:

  • High purchase cost per MB
  • Less number of records-rerecords

The HDD is still a popular choice for the majority of the average consumer, and this is because it is the most economical option and serves the need to store data (up to 6-10 TB). Of course, more and more are turning to the choice of SSD for their new computer but also if they wish to upgrade the old, as what they want is the acceleration of the system.
