    Hi,


    I'm very satisfied with my DIY NAS. Of course, isn't perfect and isn't for everyone, but i enjoyed the build and i can be "proud" for my creation.

    As you can see, SBC based NAS can work very well :)

    But... from my angle of view, RPi isn't good choice for NAS build. Of course, you can build NAS with RPi, and it can works, but i thik, here are better boards for this purpose.

    For example - NanoPI M4 - heart of my NAS have direct PCIe -> SATA (PCIe header & SATA HAT with Marwell chipset). With RPi, you must go PCie->USB (on baord controller)->USB to SATA(HAT, or USB to SATA cables). Plus problems with tons of cables, powering, etc...

    Btw: SATA HAT for RPi4


    I'm rather recommend NanoPi M4v2 with SATA HAT, or ODROID-HC4.

    If your budger is low, you can buy only M4v2, SATA HAT, PSU (i'm running with noname 12V@5A wall plug - for now, my nas have enought power to run with two 3,5" Seagate IronWolf 4TB drives) and run in mess on desk. When you save some money, you can buy/make/3D print some kind of case.

    The_Others: thanks.

    About speed: tested with NASTester 1.7. Smallest filesize what this app can test is 1MB.

    Tested via SMB share. Results from 4TB WD RED:

    And 1GB files:

    CPU & RAM usage while tests:

    (previous post must be approved, because lot of external links)

    HDD tray's needs small modification:

    1. remove black plates (red arrows)
    2. remove spacers (blue arrows) & steel axis (orange arrow)
    3. cut away parts marked with green lines (all 4) - I've used Dremel
    4. DO NOT (!) cut parts in red circles:

    Hello all,

    small update: in this week I installed new device: 256GB USB stick as my Music storage.

    USB stick, because i don't want still spin on HDD, stop HDD, spin on, stop,... with every longer song. After this my memory graph looks like this:

    So - noob question: what is buffer cache? Why this thing grow from ~20MB to ~2GB after installing USB stick?


    PS: BOM hopefully this weekend...

    Thanks all!


    3D models & pictures are attached ;)

    • battery holder: holds RTC battery & works as one NanoPI legs. Optional.

    • Bottom support: transfers the weight of the discs to the bottom of case.
    • Drive plate (final): original backpanel what you can see on pictures in first post.
    • Drive plate (vented): cgomesu asked about heat from drives. This version of backpanel have 10 holes 8x8mm in top - this can help manage temps. Not tested!

    • Left drive holder: holds drive bay in position. 4pcs needed.
    • Left drive holder: same, but on the other side :)

    BOM ASAP...

    Thank you!:S


    Ad 1.: no, enclosure is not custom made. It's BZ1715 or KYYSLB 170*150*258mm case from AliExpress. If you find a good trader, you can buy this enclosure for very good price (I've bought it under 50USD with shipping). Yes, BOM & 3D files are not problem. But 3D printed parts are designed for SLS printer, i'm not sure how about FDM printers...


    Ad 2.: right now, i'm using two Seagate IronWolf 4TB drives and I can run 100% fanless. I was doing some "stress tests" (stress test = copy & read tons of random data to/from NAS) and M4 max temp was 40°C, and drives was still under 50°C. Right now, i'm running badblocks (for curious) and drive temp is 42°C & M4 temp is 32°C. Bottleneck of this device is gbit network. But you're right, for all 4 drives & heavy traffic, some acitve cooling will be needed.


    Ad 3.: same like you :(. With Kernel 5.x was my NAS very unstable and useless. For example - copying of big files wasn't problem (usually), but lot of small files = corupted files, kernel panic & reboot.

    Hi guys!

    I have finished my own home made NAS. When i start planing this build, I set these goals:

    • low power consumption
    • cheap, but not scrap build
    • best ratio price/performance as possible

    After many days on internet, looking/comparing/... i found my ideal HW setup:

    • NanoPi M4v2
    • Sata HAT with 4 SATA ports
    • 32GB eMMC storage

    As I found later - its almost same HW setup like here:

    NanoNAS NanoPi M4 3-bay or 4-bay most compact and low consumption RAID


    But i dont like this super mini-micro setup with only 2,5" HDDs. I want something better looking :S

    So, i bought aluminium enclosure and 4HDD trays on AliExpress, make some 3D printed parts and put it together:

    Pictures are from unfinished state (I blurred the mess around)

    NanoPi is mounted at front aluminium plate (8mm thick) - it's perfect heatsink - Pi can be cooled passive.

    Rear side is 3D printed (SLS technology) holder for 4 HDD bays, 1xRJ45 keystone, 2xUSB3 keystone and power socket. Some pictures from 3D model:

    Some SATA cables, power cables, USB cables, screws, standoffs,...


    About SW: its based on Armbian buster server, linux kernel 4.4 and OMWV 5.5
