Just got all the hardware set up and working today, super stoked!

In the pic:

Raspberry Pi 5
Radxa Penta SATA hat for Pi
5x WD Blue 8TB HDD
Noctua 140mm fan
12V -> 5V buck convertor
12V (red), 5V (white), and GND (black) distribution blocks

I went with the Raspberry Pi to save some money and keep my power consumption low. I’m planning to use the NAS for streaming TV shows and movies (probably with Jellyfin), replacing my google photos account (probably with Immich), and maybe steaming music (not sure what I might use for that yet). The Pi is running Raspberry Pi Desktop OS, might switch to the server version. I’ve got all 5 drives set up and I’ve tested out streaming some stuff locally including some 4K movies, so far so good!

For those wondering, I added the 5V buck convertor because some people online said the SATA hat doesn’t do a great job of supplying power to the Pi if you’re only providing 12V to the barrel jack, to I’m going to run a USB C cable to the Pi. Also using it to send 5V to the PWM pin on the fan. Might add some LEDs too, fuck it.

Next steps:

Set up RAID 5
3D print an enclosure with panel mount connectors

Any tips/suggestions are welcome! Will post again once I get the enclosure set up.

That power situation looks suspicious.

Use ZFS RAIDz1 instead of RAID 5.

  Ultimately I would love to use ZFS but I read that it’s difficult to expand/upgrade. Not familiar with ZFS RAIDz1 though, I’ll look into it. Thanks!
  
  I build robots for a living, the power is fine, at least for a rough draft. I’ll clean everything up once the enclosure is set up.

    ZFS is so… So much better. In every single way. Change now before it’s too pate, learn and use the features as you go.

    Z1 is just single parity.
    
    Sweet build! I have all these parts laying around so this would be a fun project. Please share your enclosure design if you’d like!

    ZRAID expansion is now better than ever before!
    
    In the beginning of this year (with ZFS 2.3.0) they added zero-downtime expansion along with some other things like enhanced deduplication.

    Easier to expand than a typical raid 5 array

    ZFS, specifically RaidZx, can be expanded like and raid 5/6 these days, assuming support from the distro (works with TrueNAS for example). The patches for this have been merged years ago now. Expanding any other array (like a striped mirror) is even simpler and is done by adding VDevs.

I would argue either RAID 5 or ZFS RAIDz1 are inherently unsafe, since recovery would take a lot of read-write operations, and you better pray every drive will hold up well even after one clearly failed.

RAID6/ZFS RAIDz2 is the way. Yes, you’re gonna lose a bit more space, but added reliability is priceless.

(And, in any case, make backups for anything critical!)

Dust is going to be a problem (well, maybe not that much electrically, but it maks it a pita to keep clean) after some months, especially for the Raspberry Pi.

Consider getting (or, even better, 3D printing) an enclosure for it at least (maybe the HDDs will be fine as they are since the fan keeps the air moving and dust probably can’t actually settle down on it).

  I’ve got that covered. I got a filter for the fig intake fan. Printing the first batch of enclosure parts now.

Yeah, raid 5 in 2025 for a nas? A big no no

source
- Pestdoktor@lemmy.world ⁨17⁩ ⁨hours⁩ ago
  I’m new to this topic and only recently learned about RAID levels. Why is it a big no no?
  
  source
  - ramenshaman@lemmy.world ⁨16⁩ ⁨hours⁩ ago
    I’m in the same boat. Based on the things I’ve learned in the last hour or two, ZFS RAIDz1 is just newer and better. Someone told me that ZFS will help prevent bit rot, which is a concern for me, so I’m assuming ZFS RAIDz1 also does this, though I haven’t confirmed it yet. I’m designing my enclosure now and haven’t looked into that yet.

  TIL. Looking into ZFS RAIDz1.

  - RunningInRVA@lemmy.world ⁨13⁩ ⁨hours⁩ ago
    Also a no-no. ZFS RAIDz2 is what you want.

cellardoor@lemmy.world ⁨13⁩ ⁨hours⁩ ago
RAIDZ1. RAID 5 is historically plagued by issues and just not a reliable bet.

source
- Onomatopoeia@lemmy.cafe ⁨12⁩ ⁨hours⁩ ago
  RAID 5 is fine, as part of a storage and data management plan. I run it on an older NAS, though It can do RAID 6.
  
  No RAID is reliable in the sense of “it’ll never fail” - fault tolerance has been added to it over the years but it’S still a storage pool from multiple drives.
  
  ZFS adds to it’s fault resistance, but you still better have proper backups/redundancy.

PLA warps over time even at low heat. that said, as long as you have good airflow it shouldn’t be a problem to use it for housing, but anything directly contacting the drives might warp.

I thought about doing this myself and was leaning towards reusing drive sleds from existing hardware. it’ll save on design and printing time as well as alleviate problems with heat and the printed parts.

the sleds are usually pretty cheap on ebay, and you can always buy replacements without much effort.

  Printing the bracket for the drives in PLA now. I designed them to make minimal contact with the drives so I think they’ll be ok. Even in the rough draft setup the 140mm fan seems like overkill to keep them all cool.

  That’s a super clean build, too bad he didn’t make a 5 drive version.

I love it! The power part is what always blocks me. I would like to set up a couple of data ssds, but never know if you actually need the 3.3v part etc, so currently I put a Pico PSU on a muATX board in a way to huge tower.

nao@sh.itjust.works ⁨17⁩ ⁨hours⁩ ago

so I’m going to run a USB C cable to the Pi

Isn’t that already the case in the photo? It looks like the converter including all that cabling is only there to get 5v for the fan, but it’s difficult to see where the usb-c comes from

source
- ramenshaman@lemmy.world ⁨17⁩ ⁨hours⁩ ago
  Good catch. I don’t have my USB-C cable coming from the buck convertor set up yet, waiting on some parts to arrive tomorrow. The USB-C power is currently coming from a separate power supply in this set up. Ultimately, there will be a single 12V barrel jack port to power the whole system.

The fan is good, but the orientation seems like it would struggle pushing air between the drives. Maybe a push-pull setup with a second fan?

source
- Onomatopoeia@lemmy.cafe ⁨12⁩ ⁨hours⁩ ago
  I’d at least flip the drive on the right so it’s underside is closer to the fan, as that side gets hotter in my experience, so it would have more effective cooling.
