Hey!

 

I am currently thinking to replace my old Synology DS1812+ by a home made NAS, but I am a little lost for the choice of SSD.

 

I am targeting these components:

- Case: Fractal Design Node 804

- PSU: Corsair RM850x (or RM750x, but I want to be sure I will have enough SATA power connectors for HDD)

- MB: ASUS PRIME Z790M-PLUS D4

- CPU: not sure exactly, but I thing an Intel Core i5 with integrated graphics, TDP 65W max, like 12400 or 12500 (or maybe 13th gen if I find something at a good price)

- HDD: I will start with 3 x 16 TB RAID 5, to expand in the future to 6 HDD. I will also place 2 x 8 TB existing HDD in another RAID 1 array. Not sure at the moment which file system I will chose for the first array. I have to dig in ZFS, which I haven't play with now. For the second array, maybe BTRFS is an option too.

- SAS HBA card: LSI 9240-8i IT mode (SAS 2008 controller is enough for eight spinners HDD)

 

I want to use two SSD NVMe M.2 in RAID 1 for cache pool and VM/Docker containers. 1 or 2 TB each.

 

I was thinking to buy two Samsung 970 EVO Plus, but I have read cache pool SSD need to have a high endurance and MTBF because there are an enormous quantity of access on them.

But the more robust SSD costs double of EVO Plus...

 

I am leaning towards using EVO Plus, because of my usage :

- video files mounted in NFS shares read by Nvidia Shield (no transcoding), something similar to read my music without transcoding

- VM with Docker containers for web sites with low traffic (it seems UnRAID is capable of running Docker containers directly, but I don't know if I can keep my configurations with Traefik/NGINX/MariaDB/PHP currently running in a Debian VM in Proxmox)

- camera raws for work and photos archives

- administrative files

- ebook with Calibre Web Docker container, comics with YACReader Library Server

- other Docker containers, like UniFi

- and not actually running on my Synology, but I want to create a Windows VM to work in it on Lightroom, Photoshop and other CPU consuming softwares, and another Windows VM for some old or light games (not frequently used)

 

In my case, maybe two NVMe SSD Samsung EVO Plus at 1 TB each (RAID 1 BTRFS) will suffice? I don't know if some other people on the forum use them in this kind of usage?

 

If I have a high chance to have errors on these SSD, what would you think will be better?

 

Thanks!

 

Do not hesitate to tell me if something seems wrong to you in my config, it will be my first home made NAS!

I used to have Dual Samsung EVO Plus 1TB drives, never had an issue. That being said, I did opt to switch to WD Red NVMe drives instead when I wanted 2TB instead of 1TB.

Ok, thanks.

 

Samsung EVO Plus 1 TB endurance / MTBF: 600 TBW / 1.5 million hours

WD Red SN700 1 TB endurance / MTBF: 2000 TBW / 1.75 million hours

 

And the price where I can buy them:

- 2 x Samsung EVO Plus 1 TB: 110 €

- 2 x WD Red SN700 1 TB: 180 €

 

[Edit] After some reading, I will buy the WD Red SN700, to be on the safe side. 😛
