March 31, 20188 yr Hello, I am new to building an Unraid system and looking for feedback for the two systems, I picked. I would like to know from you, if I chose the parts wisely or if there are better options, e.g. better price/performance ratio. I would also like to hear an estimation for the power consumption, as electricity is very expensive in my country (0.29 €/kWh). Technically the "Casual" build should be enough for my needs, since I will use the system as a NAS and Plex Server with just a few clients to serve and usually without transcoding. Best regards, Hercules Casual - 1000 € 2 Western Digital WD Red 8TB, 3.5", SATA 6Gb/s (WD80EFZX) 1 Samsung SSD 960 EVO 500GB, M.2 (MZ-V6E500BW) 1 Intel Pentium Gold G4560, 2x 3.50GHz, boxed (BX80677G4560) 1 Crucial DIMM Kit 8GB, DDR4-2400, CL17 (CT2K4G4DFS824A) 1 Gigabyte GA-B250M-DS3H 1 Fractal Design Define R5 Black, schallgedämmt (FD-CA-DEF-R5-BK) 1 SanDisk Cruzer Fit 8GB, USB-A 2.0 (SDCZ33-008G-B35) 1 be quiet!

March 31, 20188 yr That be quiet! PSU is split rail, as is all the be quiet! PSUs I have looked at. This means some of the power won't be available for disks. The recommendation is to use PSU with Single +12V rail.
March 31, 20188 yr Author Thanks for you reply. I just checked the specifications for both, the WD Red 8TB HDD and the be quiet! Pure Power 10 PSU. One HDD has a max. current of 1.79A, the 12V1 can deliver 28A and the 12V2 20A. The 12V2 20A rail would be enough to run 11 HDDs and I am not planning to get that many drives.

March 31, 20188 yr I'm scratching my head around your drives: 2x spinner and 1x M.2. What are your plans? AFAIK, you can't use the M.2 as a parity or data drive. It would be a fast Cache or Unassigned Devices drive. But what to do with 2 drives? 1x parity and 1x data? Power? Yes! That hurts. I pay 0,33 EUR currently here in NRW. My two machines with 46 drives do cost me an arm and a leg ?
March 31, 20188 yr Author Hey hawihoney, one HDD will be my parity drive and the other one will be used as storage drive (for now). I am planning to use the M.2 SSD as Cache, if that isn't a problem. I chose a M.2 SSD because I don't want to "waste" a SATA slot for it. In the future I want to add additional storage drives and another parity drive. Edited March 31, 20188 yr by Hercules
March 31, 20188 yr IMHO, M.2 as Cache should work. I use 860 Pro SSDs as Cache because my Supermicro motherboards don't have these M.2 slots. Would love to have some. The difference between spinner and SSD was remarkable (~factor 3), M.2 adds ~factor 4 to my SSDs.
April 3, 20188 yr Just a note, M.2 is the format of the SSD. You can get SATA M.2, PCI-E AHCI M.2, and of course PCI-E NVMe M.2. SATA M.2 usually defeat one of your normal SATA connections, so they're best avoided. PCI-E AHCI are OK, but I don't see them much now - I have a Samsung OEM AHCI M.2 somewhere and it works fine. unRAID supports all three types of M.2.
