Hybrid hard drive combines SSD with traditional hard drives. I know that SSD can fail much often than traditional hard drives. So I want to ask that, when the SSD part of the hybrid drive fails, would I still be able to use the traditional hard drive?

If it won't work like that, then I will consider add-in SATA cards instead, as it delegates risk much better.

EDIT:

I guess it differs from model to model, so if yes what models would work. (I am evaluating Seagate DX for now)
