A traditional spinning hard disk drive (HDD) is the basic non-volatile memory on a computer. In other words, when the system is shut down, it will not "walk away" like the data on the system memory. Hard disk drives are essentially metal disks with a magnetic coating. This coating stores your data, whether it comes from weather reports from the last century, a high-definition copy of the "Star Wars Trilogy," or your digital music collection. In a hard drive, the read-write head on the disk accesses the data.
Both SSD and HDD do the same job: boot the system, store applications, and store personal files. But each type of storage has its own unique set of characteristics. The question is, what is different and why do users get one more than the other? Let's break it down: Price: To put it bluntly, SSDs are very expensive in dollars per GB. For an internal 2.5-inch drive with the same capacity and form factor of 1TB, you will pay about $75 for a hard drive, but in this article, the SSD is a huge $600. This means 8 cents per GB for HDD and 60 cents per GB for SSD. Other capacities are slightly cheaper (250 to 256GB: $150 SSD, $50 HDD), but you know the idea. Since hard drives are older and more mature technology, they will keep their prices low in the near future. These additional hundreds will push your system price beyond budget.
