Building a new NAS and want to run things by folks with more ZFS experience just to make sure there aren't any oversights.
Scenario:
Replacing a 6-year old Atom D525 build; 2x4GB ECC RAM, raidz1 3x3TB WD Red, 16GB USB thumbdrive for boot. Used primarily as storage for the family photo/video albums, music and video collection. Due to constrained space in our home I want to continue to keep the server small and low-power. The new build will be used for the same purpose, but I'll also toss on a few small services (Duplicati, ZNC, an image viewing webapp [maybe simply use NextCloud?]), no VM or transcoding duties required.
New build:
(Note that several of these component choices will hinge on the answers to my questions below, but I'll add the options here for consideration)
Edit: Will be reusing the same case and PSU (350W) and selling the old drives.

- Motherboard/CPU: Supermicro A2SDI-4C-HLN4F, Intel Atom C3558
- Official product page claims it only supports up to DDR4-2133
- RAM options (aiming for 16GB total):
- 1x Samsung M393A2G40DB0-CPB 16GB DDR4-2133 CL15 RDIMM Dual Rank ($120)
- 1x Crucial CT16G4RFD4213 16GB DDR4-2133 CL15 RDIMM Dual Rank ($140)
- 1x Hynix HMA42GR7AFR4N-TF 16GB DDR4-2133 CL15 RDIMM Dual Rank ($140)
- 2x Kingston KTL-TS421/8G 8GB DDR4-2133 CL15 RDIMM Single Rank ($95)
- OS drive options:
- 1x Crucial CT120BX500SSD1Z BX500 120GB SATA 2.5 SSD 55TB TBW Endurance ($23)
- 1x AData SU800 128GB M.2 SATA SSD Endurance unknown ($28)
- Storage drives: 3 or 4x WD80EFAX Red 8TB 5400RPM SATA3 256 MB Cache HDD
- Have seen on the forum that some folks are using a single stick of RAM instead of two and going dual channel - why is this? Purely for cost reasons?
- Given that this is a media server, is it worth investing in a L2ARC and SLOG?
- I think no, due to large sequential reads
- Suggestions for raid makeup?
- I know "when it rains, it pours" so it may not be recommended to go 3x8TB raid-z1, but I've seen several others on the forum currently doing it, as am I in my current build
- The safer route is 4x8TB raid-z2, but I wonder if I could be doing something else, like 2x8TB mirror? Also, is raid-z2 in a 4-drive array even "ok" to do?
Edit: Will be reusing the same case and PSU (350W) and selling the old drives.
