Looking to add a backup desktop hard drive [View all]

I have a solid state Samsung SSD 850 EVO 500gb running Win 10 Home.
I have a Hitachi HTS541616J9SA00 160GB as a backup drive.

My overall system is a bit old but still running fine with an Intel Quad Core 6600 on a Gigabyte GA-P35-DS3L motherboard and 8g ram.

My question is would a solid state backup drive give me better reliability?

I recently had an external HD crash and will pay the price to recover the data. I am wanting another internal HD as part of my multiple point backup plan. Plus I am getting another external drive through the company that will recover my crash which unfortunately will need a "clean room" recovery.

Thank you for any advice for adding a hard drive (type, brand, etc...). I am looking at about 2TB capacity.
