The Difference between HDD and SSD – HDD vs SSD

The Difference between HDD and SSD

When buying a new PC you will be presented with the choices to go with HDD (Hard Disk Drive) and with SSD (Solid State Drive). People often ask which one of these is a better choice, what is the Difference between HDD and SSD and the truth is that there is no real answer. Every buyer has different needs and should choose the type of hard disk according to that. SSDs’ prices have finally begun to fall but they still have advantage in price per GB. If performance is what you are looking for, SDDs are what you should go with. On the other hand if you are trying to save some money, you should choose HDD. Still, in order to be completely sure you have made a right choice, you should take a look at a full comparison of these two hard disk types.


As we have already mentioned, SSD are pretty much a new piece of technology and are still quite expensive. So in terms of price per GB, HDDs are an obvious choice. That is, of course if you are more interested in price than in performance. For example you can get a 1TB Hard Disk Drive for around 100 Australian Dollars, while for the same price you can get only 250GB Solid State Drive. Because HDDs are an older piece of technology, having been with us for around 60 years, they will remain cheaper for quite some time.


If the price is where HDDs shine, this is the aspect where SDDs have complete advantage. HDD requires some time to boot and it takes more time for a PC to turn on when it uses HDD. On the other hand SSDs will boot in seconds, and waste absolutely no time. Not only that a PC equipped with SSDs will boot faster, but will also run apps faster and will perform faster overall. The same rule applies for external drives as well – SSDs will transfer files much faster than HDDs. So no matter what you need your PC for, some extra speed can always be an advantage and if you are looking for that, SSD is a right choice for you.


Even though many people won’t even think about this aspect, it is important to consider it just as well. SSD operates without the movement of any of its parts and therefore you data will be much safer with these. The spinning platter of HDDs moves at the speed of around 6500 revolutions per minute. Moving at such high pace, chances are something might get wrong. So if you are one of those people who are rough on their PCs be sure to go with SSDs.


HDDs work in such a way that there is a head platter that rotates all the time, and therefore even the quietest HDDs will make some kind of noise. Especially when they are surrounded with all metal equipment, you will be able to hear them all the time when they are turned on. With SSDs, there is virtually no noise, since they are completely non-mechanical.


HDDs are still much more available than SDDs. Take a look at all of the manufacturers and you will many different models of HDD. You will also find these to be a part of internal memory when buying a new PC for a couple of years more at least. Even though you can find SSDs harder, this does not mean you should not get them. There are also enough models of SSD hard drives available, and if you know where to look, you will certainly find what you want. SSD models are growing in numbers and it is certain that one day they will be found in every PC.

Even though HDDs are still cheaper and more available, it is only the matter of time we are all going to switch to SSD. If you are choosing between the two of these, think about whether you are going for money of performance, and make your choice according to this.
