Risk of data corruption/loss?

I'm considering the following setup:

- Master server with battery back raid controller with 4 SAS disks in a RAID 0 - so NO mirroring here, due to max performance requirements.
- Slave server setup with streaming replication on 4 HDD's in RAID 10. The setup will be done with synchronous_commit=off and synchronous_standby_names = ''

So as you might have noticed, clearly there is a risk of data loss, which is acceptable, since our data is not very crucial. However, I have quite a hard time figuring out, if there is a risk of total data corruption across both server in this setup? E.g. something goes wrong on the master and the wal files gets corrupt. Will the slave then apply the wal files INCLUDING the corruption (e.g. an unfinished transaction etc.), or will it automatically stop restoring at the point just BEFORE the corruption, so my only loss is data AFTER the corruption?

Hope my question is clear
