Add HDD, create new pool.

[goral]

Hi everybody.
I just add new HDD (ada2) to my TrueNAS.
And before I create new pool I have question.
If my disk ada2 will fail, do I loos other pool as well or just pool on ada2?
I use not new HDD who can fail, but on this pool will be not essential data. So I don't care if will fails.
I will not extend existing pool just want create new with new HDD.
I just stop because I see this warning massage:
"A stripe data vdev is highly discouraged and will result in data loss if it fails"
Thanks for any help.
