Comparison between HDD and SSD
PC buyers didn’t have a lot of choices when it came to the storage in desktop computers and laptops until recently. While ultraportables featured SSDs (Solid-State Drives) almost all the desktop computers and laptops featured HDDs (Hard Disk Drive). However, now you have the option of selecting between HDD and SSD or in some of the cases, you can also select both.
While it is great that you now have options, the same options make the selection process daunting. To make things easier, we will compare HDDs and SSDs in this post. Both the storage options will be compared on a number of factors to make it easier for you to select one as per your preferences. So, let us begin.
As compared to HDDs, SSDs are more expensive. While a 1TB internal HDD can cost around $40-$50, the same capacity for SSD can cost more than $200. HDD is an older and well-established technology and will surely remain cheaper than SSDs in near future. The high cost of SSD can significantly increase the cost of your system.
As HDDs feature rotary recording surface, they work well with larger files which are laid in contagious blocks. This allows their head to begin and finish the read in a single continuous motion. But when the driver is full, the larger files get scattered around disk platter and the drive suffers from fragmentation. While better algorithms have significantly reduced this problem, fragmentation is still a problem with SSDs. As the read heads are lesser in SSDs, data storage can be done anywhere. This makes SSDs faster.
This is definitely the best thing in SSDs. A desktop PC with SSD can boot in just seconds and a minute at the most. On the other hand, a HDD takes some time to reach up to the operating specs. Moreover, HDD remains slower than SSD throughout the normal use. Right from booting, launching, or running a software, higher speed can definitely make a lot of difference.
SSDs do not feature any moving parts. So, if at all you drop your laptop, SSD will most probably keep the data safe even when the system is on. Most of the HDDs park their heads when the system is not being used but the head flies over its drive platter when being used. So, if you know that you are rough on the equipment, SSD is highly recommended.
No matter how quiet a HDD is, it is sure to make at least some noise when being used. As compared to the HDDs that are slower, faster ones make more noise. On the other hand SSD do not make any noise as they do not feature any mechanical parts.
As you can see, while HDD wins on price, SSD is a clear winner on the basis of fragmentation, speed, durability and noise. If it wasn’t for the price, there is no way an HDD can compete with an SSD. So, if the price is a major concern for you, a system with HDD will be a better choice and in all the other cases, SSD is the way to go.
