Does FreeNAS support RAID 1?
FreeNAS is based on ZFS, which is better than RAID. Set up a zvol (ZFS volume) with one disk redundancy, and you’ll have all the benefits of RAID 1, plus all the benefits of ZFS. If you have more than 2 drives, it will work similarly to RAID 5. The volumes are independent of your ZFS installation.
What RAID does FreeNAS use?
ZFS
FreeNAS uses ZFS’ software RAID system and it is superior to pretty much any hardware RAID on the market… as far as stability and speed. But hardware RAID has some features that ZFS does not and there are good reasons that we normally recommend hardware RAID to SMB shops.
Should I use hardware RAID FreeNAS?
In FreeNAS, the redundancy is managed by the OS and therefore the OS has to be able to access the drive directly without any unknown “filter” (in that case a hardware RAID controller for example). That’s why hardware RAID is strongly discouraged with FreeNAS.
