Do you need 8GB RAM 1000GB storage with a 17 inch laptop?
There's no relationship between one and the other.
Why, it also has HDD
RAM and hard drives have no connection to the screen.
It depends on what you want to use it for.
I would generally recommend 8 GB RAM, but with the (hopefully) SSD it really depends on the purpose.
I have a 128 GB SSD in my laptop. But that's enough even for software development, image processing and a lot of office work.
Depending on the application, RAM (RAM) and mass storage are required, as is the screen size and resolution.
(Rule of thumb: No matter how much you have - all four are always much too small.)
And is HDD enough?
It always depends on what for.
