Mixing Sata 3G & Sata 6G

Im upgrading my PC & have some old SATA 3Gb/s drives I would like to use in my new setup. The new motherboards I've been looking at have ports for the following:

SATA 6Gb/s port(s), gray
SATA 3Gb/s port(s), blue
mini-SATA 3Gb/s port(s) with onboard 32GB SSD, black

I plan to have a 256GB SATA 6Gb/s SDD as the boot drive. I have 2 questions:

Q1. If I connect the old SATA 3Gb/s drives to the SATA 3Gb/s port. Then plug the SSD into the SATA 6Gb/s port. Will the SSD speed remain at 6Gb/s or will this drop to the speed of the SATA 3Gb/s drive?

Q2. If I use a 256 GB SATA 6Gb/s SSD will I benefit from a 32Gb mini-SATA cache?

  1. Q1. Yes, the speed of the SATA 6Gb/s SSD connected to the SATA 6Gb/s port will remain at 6Gb/s.
    Q2. No, there are no benefits of using a SSD to cache a SSD. You will only see a performance boost when you use a SSD to cache a HDD.
  2. Cool, thanks
