Heat
Similar to the foresaid case, SSDs with no moving parts are much cooler than HDDS when running.

Price
As hard drives usually use more established technology which is older than SSD’s, they cost much less than SSDs. For example, if a 500GB internal 2.5-inch hard drive costs ₦10,000, above an SSD of the similar capacity will cost you more than 5 times.

Storage Capacity
The SSDs capacity is generally between 32GB-512GB. But the conventional mechanical HDDs have larger capacity that is between 10GB-4TB. Thus if you have a large demand in capacity, then HDD is a better choice for you.
