I think I'm clear now. Given:
- reducing possibility of data loss is 1st priority,
- I can live with speed issues of Z2 (compared to mirror), as I understand I'll still be able to stream video/music (the main stress i'd place on the NAS) or am I wrong here does Z2 cripple speed that much with ethe N36L procesor (link to benchmark below)
- I'm limited to 4 drives with the current box (HP proliant N36L)
- I'm not expecting to need more than 3.5TB in the next few years (it's taken me a long time to get to 1.6TB)
I'll go with raid Z2 for the 4 x 2TB
The only question is what's the best method to backup data offsite to the USB HDDs (1x 3TB, 1x 1TB):
- rysync to UFS
- rysnc to ZFS
- ???......
