NAS Build, Is the hardware overkill??

[LeviBW]

Here is a parts list for a NAS that I am planning on building in a few months, If anyone knows how to cut cost at all on this build or have any other recomendations please let me know.

maybe get a cheap ssd for boot volume, or use unraid

Will 120Gb be enough, I have a 120Gb Adata ssd one laying around

You only need that memory if you're running ZFS really (FreeNAS).

You aren't really going to get cheaper than that build brand new though other than dropping the memory down to 8GB

I am planning on using freewnas and ZFS so thats why i have that much RAM

I am sorry, but that is a bit wrong.

If you want to run FreeNAS or more specifically ZFS, you need to use ECC RAM!

ZFS highly relies on ECC RAM. I don't know enough about it, to explain why, but it is very important for data integrity.

 

BTW: For using ECC RAM your CPU as well as your motherboard need to support it. I don't know if that's the case for your CPU.

 

Also what kind of data do you want to put on there?

Is it important?

Does the NAS have to be fast? Otherwise you don't really need FreeNAS, as the price overhead is pretty high (considering the ECC RAM and compatible hardware).

I'm not sure why you're saying that's wrong?

That memory can come into use for scrubbing, de-duplication and ARC. You do not need that much memory for other types of array like storage spaces, mdadm, xfs/btrfs, unraid, flexraid, etc...it doesn't utilise memory in the same way for tasks. Hence stating, it depends on the array type, on how much memory he requires for his build.

 

As for ECC - that doesn't protect against multi-bit errors, pending sectors, disk failures, power surges, and other events that can occur. While its a good idea it is not mandator for home use and not the be all and end all. Bit-flips in memory are not that common.

Sorry, I might have written that a little fast/confusing, I just meant the ECC part.

Multi-Bit errors should be more unlikely than Bit-flips, right?

And isn't something affecting the drives is why one would use RAID?

 

All in all I just thought, that OP should read up on that topic.

[PARisboring]

The only issue I see is the LAN chip on that motherboard. You want an Intel NIC for sure. 

 

As for ECC memory: You DO NOT need ECC for FreeNAS. It's recommended to use ECC, but there is nothing special about the ZFS filesystem that would require ECC any more than any other filesystem.

[Gerr]

You're paying a premium for the small ITX size.  Consider Micro-ATX and you will save some money.

 

Those HGST NAS drives are top notch, but if you are looking to cut corners, think about WD Red or Seagate's NAS drives instead.  Also, why 4 drives?  Just use Raid1z with 3 drives.

 

I would suggest a lower wattage Gold PSU like Seasonic's 360W Gold.

 

ECC is a nice thing to have with ZFS, but not needed.

 

You don't need an SSD if you are using FreeNAS, just a pair of USB drives.  Unless you plan on a read or write cache.

 

RAID provides redundancy, but is not a backup.  Do you have a solution for that?

Get a small SSD or Big usb stick to run Freenas of,  The base os will not install on a drive and allow the use of that disk for data.  (also for log's or simple jails) it nice if the array doesn't have to spin up
