The performance benefits of SSD over HDD.

Hard disk drives also known as hard drives are widely used today and will most likely be used in the future.  However, many people have been buzzing about Solid State drives (SSD) and are for a good reason. The reason is that SSD is a far better alternative storage device than HDD when it comes to performance. Let’s highlight three topics that will help you to better understand.



A hard drive failure can happen anytime and it can have catastrophic consequences such as losing all documents, photos, music and other important data. One of the key differences between a SSD and a HDD is that a standard HDD contains electrochemical meaning that it has moving parts containing a disk that spins thousands of times per second and a moving read/write head.  Due to all these moving parts, HDD can often fail because of normal wear and tear from constant use or from an accidental drop. As oppose to HDD, SDD contains no moving parts because it stores all the data on microchips much like the well-known USB flash drives. No moving parts mean no wear and tear. It also contributes to being immune to physical vibrations, shock and extreme temperature. Basically, nothing will happen if you accidently drop it, which can be very appropriate for people who travel constantly. In addition, SSD also consumes much less power and produce very little heat than HDD.



HDD are slower because you must wait until their moving parts get into place before they can read files or save information. On the other hand, SSD can immediately find read or saved data without having to wait around. In addition, SSD can read/write about twice the speed of HDD. What does this mean for the performance for your computer? It means your computer will boot up fast and applications such as video games and other programs will load much quicker. SDD are very quiet because it does not have a spinning disk like the HDD that produces noise when it goes to retrieve data.  HDD also becomes fragmented overtime as files are removed on and off the disk. Fragmentation occurs when a HDD cannot or will not allocate enough space to store a complete file in a physical continuous space on the disk platters.  Fragmentation will greatly increase the read and write times of the hard drive which slow your computer down. However, SDD does not have fragmentation as an issue.




Compared to HDD, price and capacity are the two main disadvantages of SSD. This is why most people still use HDD over SSD’s great performance because they are looking for a lot of storage at an affordable price. However, in the past few years SSD has significantly dropped in price from when it first came into the market.
