SSDs are faster and take less room in a PC than a hard-disk drive (HDD), which gives them a strong advantage. If you only have one storage drive in your PC, it should ideally be an SSD so you get faster boot times and quicker access to your files. A HDD as your primary drive will feel much slower. But HDD still have their advantages. First, they're much cheaper. The going price of a 2TB HDD is about the same as the sale price for a 1TB SSD. You also can get them in higher capacities than SSDs. If you work with huge files, you can pick up an 18TB or 20TB HDD (and as mentioned, since HDD cost less, you'll spend as much or even less as a 4TB SSD). f you need secondary storage and you don't need it to be fast, HDD are a fantastic option.
