Though there are a plethora of advantages, FreeNAS is not without its disadvantages: Saves power and increases disk lifespan by spinning down unused drives.Data on functioning drives remains available during resilvering.Parity drives protect large numbers of drives without reducing capacity.Uses the maximum capacity of all data disks.

Here are some of the advantages you can expect with UnRAID.

Fault tolerance with as few as two drives.

Standard RAID modes offer increased speed plus fault tolerance.

Here are some common advantages that youвЂ™ll find with both FreeNAS and UnRAID:ДЇreeNAS provides some advantages that are unique to itself. Hard drive reliability has increased drastically in the last decade from the 7% per annum failure rates Google and Carnegie Mellon studies revealed, but itвЂ™s still a calculated risk protecting only two of say twenty disks. The obvious downside to the UnRAID approach is that as the number of data disks increases, so does the number of failure points. This provides protection from one or two disk failures.

UnRAIDвЂ™s major advantage is that it allows one or two parity disks to protect an unlimited number of data disks, all of which retain their full capacity. Unlike JBOD, however, files are spread across all the data disks, and donвЂ™t just fill one spill to the next when the first is full.Д«eyond that, RAID 5 uses XOR parity, while UnRAID uses Even Parity which are merely different roads to the same effectвЂ“fault tolerance (the ability to withstand loss of disks). UnRAID offers only one method, and itвЂ™s similar to the dedicated parity disk RAID modes (3, 4 etc.), but with the difference that thereвЂ™s no striping involvedвЂ“just plain disks with file-level writes as with JBOD, but block-level parity written to a dedicated parity drive.

RAID 6 вЂ“ Block level writes distributed across disks, double distributed parity.

RAID 5 вЂ“ Block level writes distributed across disks, distributed parity.

RAID 1 вЂ“ Mirrored block level writes distributed across disks.

RAID 0 вЂ“ File level writes, data duplicated on additional disks with no fault tolerance.

The basic RAID modes offered by FreeNAS and its OpenZFS file system are: Storage HandlingДЄs mentioned, but far the most salient difference between FreeNAS and UnRAID is how they handle fault tolerance.

This main dashboard of FreeNAS provides information on general system and storage status. The FreeNAS interface looks different, but offer the same essential abilities to configure and manage the storage, as well as associated services such as VMs and Docker. UnRAID array with parity and caching drives FreeNAS uses the traditional RAID modes baked into its OpenZFS file system, while UnRAID uses a file-level distribution system that bears more of a resemblance to JBOD crossed with RAID 3/4, than RAID 5 or such. However, cost is a trifling issue compared to the difference in how they handle storage. The most obvious difference is that FreeNAS is freeВ and UnRAID isnвЂ™t, though itвЂ™s not expensive as such things go, being $60 to $150. From there, while sharing features such as the ability to organize data, run VMs and Docker, FreeNAS and UnRAID part ways.
