2 HDD Raid Recommendation

[PhilInCA]

In another thread today I finalized and ordered my first NAS box. In reading many posts here with the RAID topic, people are running quite a few drives. I will be starting with only 2x 3TB WD Reds. I'll be running a SuperMicro X9SCM board and using the onboard controller for the drives.

There seems to be quite a few comments that FreeNAS has a pretty good RAID-type(?) ability built in. I've yet to use any NAS OS, so what do you recommend my setup look like?

Wish list/Criteria:

• 3TB is plenty for me at the moment.
• I would like to be safe in the event of a disk failure
• I would like to be able to add an additional disk, 2 if necessary, in the future if storage expansion is needed.
• Basically, I just want my data to be safe (of course).

Sorry if I'm not asking or framing the question properly.

Nevermind... found the answer to my own question. It didn't show up in my first few searches.

Be warned you can't add disks to a vdev after its been created. Read the presentation in my SIG if you are confused.
