Choosing between SSD or HDD is not as easy as one might initially think. Because both have advantages and disadvantages. Ultimately, it depends on the intended use.
In this blog article, we will explain the reasons and show you the difference between SSD and HDD.
this video briefly explains what SSDs actually are and how they differ from normal HDDs:
SSD or HDD? What are the differences and what is better? – Those are the questions here. Recently, desktop PCs and laptops have often combined both. And that makes perfect sense.
In this case, the boot partition is on the SSD and ensures that the computer starts quickly. All normal data files and less important programs are stored on an HDD. But why are SSD and HDD not equally suitable for every use?
SSD or HDD – difference, advantages, and disadvantages
If you are faced with the decision to buy an SSD or HDD, then several criteria will help you decide. On the one hand, there are differences between SDD and HDD: An SSD allows much faster access to the data.
On the other hand, these fast drives are also significantly more expensive . In addition, they are not yet available in really large dimensions – at least not affordable.
In most cases, SSD’s are used as a boot drive, memories with a size of 128 or 256 GB are usually used, while HDDs that are ten times that size are installed at the same time.
Nevertheless, if speed is your main concern, then the SSD is the right choice. There is no question of whether an SSD or HDD will win the race, as the SSD is on average four to five times as fast as a conventional hard drive.
SSDs advantages are obvious: they are fast, requires less power (important for laptops!), Makes no noise and does not require any significant cooling. However, there are two important characteristics of the SSD that speak against it.
On the one hand, SSDs have much more trouble with interference. In the event of a power failure, not only is a file lost, as is the case with an HDD, but it can also lead to major data losses and even total failures.
On the other hand, the SSD compared to the HDD has limited rewritability. The normal hard disk with rotating magnetic disks has the edge here. In theory, it can be deleted and overwritten an unlimited number of times.
This is not possible with the SSD. These memories wear out with every write access. In the long run, they get slower and slower. So you shouldn’t use an SSD as the main hard drive in systems that are constantly being accessed and modified.
Laptops with an SSD as the only hard drive are just as undesirable as servers that are equipped with SSDs.
The solution: SSD and HDD!
In the everyday life of most users, the question does not arise whether one has an SSD or HDD. The newer devices often have both, whereby the SSD can show its strengths as a boot drive while you store the countless photos and all your other files on the HDD – especially if you use them frequently and thus generate a lot of write accesses.
Incidentally, it is also advisable to put the temporary storage locations, such as the Windows or Firefox Temp folder, on the HDD. Because files are constantly being written and deleted again without wanting to keep them. All of this comes at the cost of the life of an SSD.
