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:

CPU & RAM usage while tests:

Not sure, if feature, bug, or bad config... After restart, charts lost data from last month of operation...

Trupik · 7. November 2020

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

HDD tray's needs small modification:

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

Thanks. I know this page and i'm understand this not "eat" my memory

I'm curious, why buffer cache grow from 20MB to 2GB after USB stick was installed?!

Trupik · 6. November 2020

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...

Trupik · 29. Oktober 2020

I like these charts

Part 1: copying about 0,7T of data - 1Gbps (HDD temp @ 40^oC)

Part 2: streaming some movies to network

Everything other: idle (i was in work)

Trupik · 26. Oktober 2020

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...

Trupik · 24. Oktober 2020

Thank you!

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.

Trupik · 24. Oktober 2020

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

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
