Storage Spaces: Dual Redunancy?

I am trying to read
https://technet.microsoft.com/en-us/...(v=ws.11).aspx

Under "Resilient storage", I see

"Mirror. Writes data in a stripe across multiple disks while also
writing one or two extra copies of the data. Use the mirror layout for
most workloads – it helps protect your data from disk failures and
provides great performance, especially when you add some SSDs to your
storage pool and use storage tiers."

Is this telling me what I hope it is: that I could set up a Storage
Space across a dozen or so drives and have up to two drives fail without
losing data?
