SSD vs HDD - The detailed comparison
SSD vs HDD - What do you need? Most people today buy laptops for computer use. You then have to choose a Solid State Drive (SSD) or a Hard Disk Drive (HDD) as main memory. Which of the two memory types is the better choice, the SSD or an HDD?
The question of the right hard drive is the question of your preferences
There is no simple answer to the question of "the right disk". Each user has different needs and you have to weigh the decision based on those needs, preferences and of course the budget. Although the price of SSDs has dropped, the price per gigabyte compared to HDDs is still very high. But if performance and fast boot up are paramount - and money is secondary - then SSD is the option. In the remainder of this article we will make a comparison SSD vs HDD. We are referring to the good, the bad and the ugly of both.
What is an SSD?
SSD vs HDD for graphic design
Graphic designers especially benefit from the fast SSD
We will not make any assumptions here and keep this article at a level that anyone can understand. You may buy a computer for the first time and just ask yourself what the damned SSD means? SSD first stands for Solid State Drive. You are probably familiar with USB sticks. The SSD can be regarded as an oversized, more sophisticated version of the simple USB stick.
The mechanical movement slows down the HDD
As with the memory stick, there are no moving parts in an SSD storage unit. Rather, information is stored in microchips. Conversely, the hard disk drive uses a mechanical swivel arm with read / write head that reads information from the correct location on the disk. This difference makes the SSD so much faster.
Analyze for yourself: What is faster? They go through the room to get a book and get information. Or you just have this book lying magically in front of you when you need it? That's the difference of the systems SSD vs HDD: The inclusion of information requires more physical work (mechanical movement).
The memory of an SSD can survive you
A typical SSD uses a so-called NAND-based flash memory. This is a non-volatile memory type. What does non-volatile mean, you ask yourself? The simple answer is: you can turn off the drive and it does not "forget" what is stored on it. Of course, this is an important feature for any type of permanent storage.
In the early days of the SSD there was a rumor that the stored data could wear off and get lost after a few years. The rumor is of course from today's point of view nonsense. You can read and write an SSD throughout the day, and the integrity of data storage stays in place for well over 200 years.
In other words, the memory of an SSD can survive you!
A good controller distinguishes a good from an excellent SSD

The SSD controller is part of the chipset
An SSD does not have a mechanical arm for reading and writing data, but an embedded processor (or "brain") called a controller to perform a series of operations related to reading and writing data. Control is a very important factor in determining the speed of an SSD. The decisions that it makes regarding the storage, retrieval, caching, and purging of data determine the overall speed of the drive.
We will not go into the details of the various tasks that will be performed. Suffice it to say that a good controller sets a good one apart from an excellent SSD.
Technical data - and what does an SSD look like?
Finally, you might wonder what an SSD looks like and how easy it is to replace a hard drive with a successor device. If you look at the following pictures, you will see the top and bottom of a typical 2.5 "SSD. The technology is either housed in a plastic or metal case and looks like something that could be a battery.
