When buying a new PC or updating the disk system of an old electronic computer, the question necessarily arises: “Which is better - SSD or HDD?” Five years ago, this question did not arise. There was no alternative to a conventional hard drive (its second name is “Winchester” or simply “screw”). Therefore, it was precisely such devices for storing information that were used universally. But now the situation has changed dramatically. Increasingly, users are paying attention to solid-state drives, which although they are more expensive, but at the same time they have a much higher performance.
Story
Before we find out what is the difference between SSD and HDD, let's take a short historical digression and look at the data storage technologies that are used in each type of device.

Comparing the performance of each drive, it can be noted that solid-state drives have a higher data transfer rate. This is provided by the technology itself. Microcircuits in this regard are better than magnetic plates. This is where the benefits of this type of device end. If you compare the cost and size of the drive, it turns out that at a price of 40-50 USD you can buy either 32 GB
SSD, or 160-250 GB of HDD. Hence the choice of most users. At the same cost, a larger volume will be better than speed. Also, the maximum capacity of an HDD is 8 times greater (1 GB vs 8 GB).What and where is better?
