*Description and testing under construction*

#Purpose build:
Long time reliable storage. Not a 24/7 system. Mainly used for archival of multiple media files and documents. Capability to sync directories to offsite location.

#Important:
2 drive failure. RaidZ2 with 8 disks.
ZFS and ECC for rock-solid base.
AES-NI for disk encryption acceleration
Order 2 batches of 4 disks from 2 different web shops.

#Not Important:
Fast cache for frequently accessed files - L2ARC
10GBit network (not yet..)
Power consumption
Bleeding edge hardware. Function over form.
Noise - Fans full speed from BIOS. Hottest disk 31 degree on a hot day.

#Notes:
* Cooling
2 stock Fractal Design fans in front of the 8 drives. 1 Noctua as exhaust fan.

* Storage
Although 8x4TB is 32TB, -2x4TB (redundancy disks) = 24TB, the raw usable storage is +/- 20TB. Any 4TB disk is never 4TB. It's more like 3.6TB. It's much more complicated, but I would say it's marketing I guess..

#Bottleneck
Uploading/downloading files to the NAS is currently limited by the Gigabit NIC. That could be solved by NIC-teaming for multiple clients at once, or upgrading to a PCI-e 10GBit card.

Moving files between "datasets" (a directory/folder/mount), encryption/decryption needs to happen. However this CPU has AES-NI which helps, CPU load still spikes at 85% when moving files locally between datasets. Upgrading to other CPU could mitigate this. Not a big issue for now.

#Personal story
I used NAS4Free for 8+ years using re-purposed hardware without issues, using Software RAID1 setup for important files. Software RAID, discouraged by many, however very convenient in case of hardware failures. After seeing my SMART data, saying "consider replacing disk(s)", I decided to purpose build a new NAS with all preferences stated above. ZFS needs lots of memory, which is costly these days. There are mixed messages about ECC memory. Looking at pricing, it did not really matter much if it is ECC or not and was more a peace of mind. Having build "the thing", I enabled SSH on the box and copied all my files from multiple machines to it. However SCP is slower than FTP, I wanted to keep the original timestamps of the files. Especially for my pictures. Sure meta-data.. I just want it this way..! (scp -p) Around 8TB file transfers later and a SCRUB without issues, I decided my benchmark/burn-in was done and the system is reliable. Hope this system will serve me the coming 5-10+ years.

From an old desktop, I build my brother a NAS4Free box, using 2x4TB WD Reds in Software-RAID1 and some spare disks. Using Syncthing I will sync my pictures to his NAS on a read-only share, and sync his pictures to a read-only share on my NAS. Read-only for users on SAMBA/NFS shares that is. If something burns down to the ground, we still have the pictures! :P
