raid1 on 628x
how can i setup raid1 using an 8 bay 628x, with 8x10t drives

If you truly want RAID1, then you need to create 4 volumes, one for each pair of drives. Each volume is 10 TB, and has two drives that are mirrored. So 40 TB of total space. But you need to manually create shares on each volume and balance the space.
But from what you say, it sounds like you actually want RAID10. This is a hybrid RAID mode (1+0) that is described here: https://en.wikipedia.org/wiki/Nested_RAID_levels#RAID_10_(RAID_1+0) It would give you a 40 TB volume, comprised of mirrored pairs.
RAID6 would protect against any combination of 2 disk failures, but always fails with 3 or more disk failures. RAID10 fails with some combinations of two disk failures, but will succeed with some combinations of 3 or more drive failures.
Please read through the wiki article, and get back to us on the raid mode you want.
FWIW, RAID in any form isn't enough to keep your data safe. It is helpful, but you do need a backup of your data on other devices in order to keep your data safe.

Do you mean RAID0 or RAID1? RAID1 is disk mirroring, so you have 4 volumes of 10 TB each.
RAID0 would be a single 80 TB volume that has no RAID redundancy. FWIW, I agree with Sandshark that RAID-0 is quite risky, especially with a volume that large. If any disk fails, then the entire volume is lost.

- as the article says raid1 is mirrored disk, the same data written to 2 disks, giving me 40tb out of the 80tb. if any 1 disk fails it may be replaced without loss
