What kind of hard disk is SSHD?

pu1. It's a combination of ssd and hdd.
In the past, ssd was too expensive and the capacity was small, so it was difficult to use it in real life.
So we write ssd as cache and the actual data is stored in hdd

OK

pu2. It's a bit of a vague hard drive now
I didn't know that SSD's unit price would go down a lot like now and the large capacity would be this fast.
And for those who need the capacity, they can just add hdd and use it separately, so they can use it more cheaply.
For now, you can just buy ssd if you want to open the window, and hdd if you want to use it for storage.
