One PBS with raid1 or two with single discs?

Which solution is better:
1. One PBS host with two disks raid1
2. Two PBSs with single disc and sync from one to two?
Hardware costs doesn't matter.

 

[longer]

Between this 2 options I would go with Raid1.
If more disks possible then maybe Raid 6.

Two independent PBS' with two disks each ;-)

1. One PBS host with two disks raid1
2. Two PBSs with single disc and sync from one to two?

In this specific case, without any other option: there are multiple elements in a system that may die - starting from the power supply over the CPU and chipset to RAM. The disk is just one element.

With this in my mind: I would expect option 2) to be more reliable on the long run...

I also like the idea of two servers versus one if forced to pick, but also with the added arrangement that the servers are geographically separated.
