HDD’s vs SSD’s - Which is the best option?

What are HDD’s (Hard Disk Drive)?

  • HDD’s were brought to the market by IBM in 1956, however the modern HDD as we know it, only came to fruition in the 1980’s, from then, the design of HDD’s has remained largely unchanged.
  • HDD’s rely on physical forces: movement, and magnetism. They power a series of spinning disks, which will eventually wear down the more they are used.

What are SSD’s (Solid- State Drive)?

  • SSD’s use flash memory and no moving parts, the same technology within SD cards and thumb drives, giving them enhanced life-span and reliability.
  • SDD’s electrical infrastructure, rather than mechanical like HDD’s, make for rapid speeds.


  • The lack of moving parts and flash technology inherent within SSD’s means they are able to achieve much higher read and write speeds, an incredible 100 times faster.
  • HDD’s are prone to fragmentation- this is when the system becomes overloaded with information which is then written over many different sections making the files slow to read, this does not occur within SSD’s.


  • Higher end SSD’s used to have less storage capacity than HDD’s. This is changing however, with 1TB and 2TB options becoming more readily available and affordable.


  • As they contain no moving parts, SSD’s are much more shock resistant than their HDD counterparts.
  • The mechanical parts within HDD’s mean that they are more prone to overheating if not adequately cooled. The installation and maintenance of a cooling system can prove more costly in the long term than purchasing an SSD. 

Form Factor:

  • HDD’s generally come in sizes of 3.5-inch or 2.5-inch disks. 
  • SSD’s generally come in 2.5- inch drives.
  • The size of HDD’s stopped decreasing due to functionality issues, whereas it is expected that SSD will continue to become smaller.

Noise and Efficiency:

  • SSD’s are much lighter and are effectively silent due to the lack of moving parts, this makes them a lot cooler/ power efficient.
  • Even the quietest HDD will make noise.
  • SSD’s’ enhanced energy efficiency means that you save money per GB, in the long run, and on air conditioning and cooling units.
  • SSD’s are able to maintain peak performance for longer as they use each part of the drive equally and use reserve flash to replace slow or bad blocks.


  • SSD’s are a lot more cost effective when factoring in long-term cost savings in power usage.


  • SSD’s are fast becoming the norm, testament to this is the fact that many newer systems do not have HDD’s as a configurable option. 

Which is Right for You?

SDD Benefits:

HDD Benefits:


Cheap storage backups


Easy repairs                       

System intensive operations      

Cost- effective, scalable capacities




Power efficiency (long- term cost savings)



As the price point for larger storage capacities continue to fall, the reasons to purchase HDD’s become obsolete. At this point, the primary motivator to buy an HDD is its cost effectiveness, however, as economies of scale adjust these reasons are dissipating making SSD’s an ever- more attractive option for enhancing your productivity and system performance.
