Yes, you can add another RAID 1 with different size drives. I don't foresee any issues with your plan. You can find information on the storage controller in the manual on either the system or storage controller support page.
The S110 should support drives larger than 2TB. Storage controllers that support drives larger than 2TB don't typically have a maximum supported drive size specification since it is theoretical. I don't think there are any drives approaching those limits. I would review the specifications in the manual to be certain.
You should avoid parity RAID levels on a controller without write cache. It will be very poor performance, and it will affect performance across the entire controller.

Do you think adding 3 2TB disks with RAID 5 be better? Also does the PERC S110 support 4TB drives?
