Display MoreYour storage requirements will dictate what options are available to you.
How much storage do you require? What kind of redundancy?
You say plugging in up to 4 drives, but what is the reasoning? Are you wanting a RAID, or are you saying that thinking of capacity?
If it's just for capacity, the DAS option is still doable, just don't try to do a RAID over a USB connection. Alternately, there are some very large drives available in up to the 20+TB range so 2 drives with an rsync backup can give you redundancy without the unstable RAID over USB issue.
...and if the external drives are esata connected you can still do an OMV MD RAID if required.
If you want to keep it to a USB connection an external RAID enclosure would also work, but OMV will not be able to monitor for a single drive failure as the enclosure is presented to the system as a single drive/filesystem, and the RAID management is done in the external enclosure. You would have to rely on alarms from the enclosure if a drive fails. This could easily work with your Raspberry Pi option or an N100 with limited connectivity.
I have one of these (see below) with 5 x 10TB drives in it configured to run as a RAID 5. It ran as 24/7 storage attached to a NUC running OMV for several years. Now it is my Backup array where data from all my live arrays get copied to. Once again, something similar would work fine with your RPi option, as it isn't too far off the NUC setup I had with it. Orico make several different enclosures like this (ie. 4 bay, 5 bay, front load, top load, HDD, SSD, etc.), so just pick one you like as long as it has RAID capability.
The data that I will like to have into the NAS are now in a 2 TB 3.5 HDD in my PC. Only a half of it are free (1TB approximately). The type of files that are saved are: photos, videos, text documents, etc. That I open them rarely.
The main objective is saving into the NAS that files + sync/backup photos from two mobile phones and other backups.
My idea is making a RAID 1 with two 4 TB 3.5 HDD (where I will save the data decrived above) and leave initially free the rest of slots for futures needs.
Then I will use two external HDD to make backups peridiocally for data are saved into the NAS.
Then I will use a SSD (240/500GB) for Operative System (OMV).
I hope that I will be a good strategy.
Also, I should add that if you want to go the N100 route as Chente did, It doesn't have to be the exact same Asus board he used. Asrock makes N100 boards in both the ITX and Micro-ATX form factors. The boards have 2 built in SATA ports instead of the 1 on the Asus board, and the M-ATX board has 2 pcie slots (1@ x1, 1@ x16 size running in x2 mode) so to get an extra x1 slot which increases the ability add an extra NIC or SATA card if required.
Likewise, with these systems, externally connected storage is still possible for expansion.
If I was building one of these i would probably lean toward the micro-atx form factor for the extra pcie slot and the fact that there are a lot more options for cases that take ATX style boards with internal HDD bays than there are ITX cases
The motherboard AsRock Mini-ITX (N100DC-ITX) could be interesting as you said, it has two SATA ports and I could be used initially my RAID 1 with two 4TB HDD. And then, on the future if i would have need I could buy an adapter PCIe or M.2 to SATA adapter.
But I have seen that AsRock Mini-ITX (N100DC-ITX) have to be external power supply and it could be a problem if on the future need to plug more HDD.
The other motherboard AsRock Micro-ATX (N100M) the power supply into the case. More easy to giving power fore more disks, although I will have to consider that it is an Micro-ATX, that it means a bigger case.
Also I have seen other motherboards brands as:
- https://androidpc.es/placa-base-pasiva-intel-n100-i3-n305/
- https://cwwk.net/products/cwwk…tx-board-type-motherboard
They have 6 SATA ports integrated. Are them as the same quality as Asus or AsRock boards?
At this moment, my candidate components are:
- Mini-ITX Jonsbo N2 or Fractal Design Node 304 (+/- 100 €) Jonsbo N2 / Fractal Design Node 304
- Asus PRIME N100I-D D4 (108,80 €) ASUS Prime N100
- PSU Cooler Master V850 850W SFX Gold (167,98 €) PSU Cooler Master
- M.2 to (x6 SATA) WANGCL (26,99 €) M.2 to (x6 SATA) WANGCL (I think that it doesn't use port multiplier as chente commented)
- HDD Seagate IronWolf 4TB (x2) (230 €) Seagate IronWolf 4TB
- SSD 240/500 GB (x1) (0 € already have someone)
- SATA cables (12€) SATA III
Total: +/- 645€
Taking a walk on some of main NAS manufacturers:
- QNAP TS-453E-8G (782 €)
- Asustor Drivestor 4 Pro Gen2 AS3304T v2 (415 €).
In all cases I would get a system with less options and performance and in addition I have to add 230€ for HDDs.
What worked best for me was my NAS from TerraMaster (T6-423).
The Qnap TS-853A also works well. You need to install fanncontrol yourself.
The other NAS from Qnap that I have / had work(ed) well, but I had to investigate some small issues (e.g. adding special params to the bool command line).
TerraMaster (T6-423) and Qnap TS-853A I think there are high price and also I need to add the HDDs.
