Freenas Learning build

[Nimbu]

Hey Guys,

I posed a little while back, but I never got around to putting this test rig together. However I have found some time this weekend so wanted to just double check. Intended use: I'm no stranger to NAS, both homebrew and off the shelf, but I wanted to learn about freenas. If this system does make it into production its likely to be an onsite backup for a small subset of my data that lives on my Synology DS1815+

Hardware:
HP Microserver G8
i5 (cant remember the exact model)
8GB ECC

Drives / Array:
Given that this is a test system, I am going to be using 4 x 2TB hard drives. I do plan on playing with the different raid types. Though I have one burning question, my synology is my current nas, set in shr2, which also backs up a small subset of data to the cloud. Eventually I want an onsite backup of this data set. Whilst I intend to try out the different raid levels. Would I be crazy to consider RAIDZ3 for a 4 drive array? The data is very static and small (15GB total). The reason I am considering RAIDZ3 is that this gives me the ability for any three drives to fail before data loss.

Any thoughts or suggestions appreciated.

RAIDZ3 on 4x2TB will give you only ~2TB of storage space.
Go with raidz2,the discs are small, the fact that each disc is only 2Tb means less of a chance for a drive to fail during re silver.
If it were 4+ 10TB, maybe because there is a beter chance for an error during a resilver.

Like what Tfran said Raidz2 Unless this data is a must have and can not be lost then Raidz3.
Raidz2 is a middle ground of both worlds as Raid5/Raidz1 is being Phased out with larger capacity drives. (Look up why raid5 is Dead/bad)
Raidz3 is going to offer the most protection, and with the smaller sized drives you are using In my eyes Raidz3 seems not to be needed.
