Build a Raspberry Pi CM4 4-Bay NAS with Wiretrustee Carrier Board

There are a few people currently working on NAS boards based on the CM4. A few different approaches in terms of chipsets used and performance targets.I'm trying to track them in this GitHub issue [1] but a couple people have remained more or less anonymous as they don't want to attract attention too early.The single PCIe lane is the biggest limitation if you're looking for raw speed (350 MB/sec is kind of the upper real-world sustained transfer limit), though since the gigabit Ethernet port is on a different interface, you can still expect to get 80-100 MB/sec network transfer speeds.Something like this, with the right case and OMV or other adequate software would be a relatively competitive replacement for low-end NASes.I'm also exploring building a 2.5G NAS with a CM4, but the PCIe bus speed limitation is what kinda hamstrings that. Hopefully the next Pi revision has a 4x (at least) lane, like the RockPro64.[1] <a href="https://github.com/geerlingguy/raspberry-pi-pcie-devices/issues/25" rel="nofollow">https://github.com/geerlingguy/raspberry-pi-pcie-devices/iss...</a>

Nothing against cool RPi projects but be aware that a motherboard with a NAS-grade Celeron, like ASRock J4105M, sells for $85 or so (but needs RAM, $20 for 4GB roughly). At $105, this leaves this carrier board around $35 of budget if you can get RPi CM4 4GB for $70. Plus all the doubts about reliability mentioned above.

Do not buy ROCK Pi SATA HAT. I own one, and after few months of lite usage with 4 SSDs, one channel (two SSD connectors) has just died. I just installed OpenMediaVault and configured LVM on 2TB, 2x 1TB and .5 TB SSDs, to use it as a home media server.I recently tried to initialize warranty process (I bought it directly from shop.allnetchina.cn with shipping to Central Europe) but I got no replay.

That looks a lot like the mainboard from the Western Digital Sharespace I had about 10 years ago.I was recently wanting a NAS again, but came to the conclusion that the best bang for your buck was just grabbing a cheap mini-ITX board and processor as the price of dedicated NAS boxes was not much different and was far less flexible. Then you would have full-fat sata, even m2 for a boot drive, whatever RAM you wanted etc.I know it's not a very exciting solution...

Title is misleading?End of the article : There’s close to no information about the software right now, and the hardware is not available yet

Nice, but the Gen10 HP ProLiant Microserver is my NAS platform of choice.It supports ECC and has 4 cable-free swappable bays plus space for an SSD system drive in the top. The bolts-as-caddy system is also a great idea.

You can have a lot of fun with Pi's, but I'm not sure I want to build a multi-TB NAS using a Raspberry Pi with a pretty rare addon board..If you do want something like this, I think the ODROID-HC4[1] is probably a better option.1 - <a href="https://ameridroid.com/products/odroid-hc4" rel="nofollow">https://ameridroid.com/products/odroid-hc4</a>

I would still defer to something with ECC RAM and ZFS for keeping my data, but I could see myself using something like this for unimportant data and/or serving important data as a read-only mirror. Either way, I love that an RPi system will soon come in a sweet form-factor optimized for NAS use.

As a cheap offsite destination for backup,(assuming you have multiple destinations) this looks quite compelling.Although I don't think ZFS is stable on the pi just yet[1], so perhaps 4 sata drives is overkill.I would be interested in a single sata/cm4 carrier board though.[1]citation needed, I've not really looked...

I wouldnt trust my data with this kind of devices. There's nothing wrong per se, but I have my doubts about how easy you can find replacement parts if something breaks in, say, a year or two.If you really depend on your data and want it to be safe, i'd recommend spending the extra money and either getting a proper nas (synology/qnap) or go the proper diy way (aka an x86 box and truenas/unraid).you really don't want to be in the position where you absolutely need your data but the replacement parts are two-weeks far in the future because they're travelling via snail mail or worse, relying on 2nd-hand spare parts off ebay.edit: not to mention, the gigabit ethernet port is a bottleneck. you would probably hitting the bottleneck even by using four rotational disks.

Here's what I want, but haven't been able to find:I already have a beefy server at home ( it's actually a refurbished enterprise workstation, with 24 cores, but read on ).However it lacks drives. What I ideally want is a a dumb drive bay I could buy, and then connect ( somehow ) to my existing server, so I could use its CPU and RAM.I don't want this drive bay to have its own CPU, I just want it to hold data and transfer it over some wire. Ideally I would achieve close to gigabit speeds requesting data off of this server/drive bay.Some options I've explored are those dumb quad storage bays that connect over USB-3. But I was worried about running ZFS over a USB interface, as well as potentially parallel read and writes with the quality of the USB controller.

Use RPi for NAS is really a stretch. Just buy those low-power x86 mini-itx boards with 4GB memory and 4 SATA ports along with gigabit ethernet, they're around $150?Note the smaller size of RPi-etc makes no sense when you're going to host 4 hard drives anyways which takes quite some space on their own, and you need a decent PSU for the drives too, and a solid case as well, etc.Just buy those ASRock mini-itx boards at newsegg or somewhere and let RPi do what it's best at.

A quick google shows eMMC flash memory for the compute module...do you need to mindfully control writing to flash to keep something like this from nuking the boot device? Could be my choice of storage (whatever $4 buys at Microcenter) but the failure mode on my RPi weather station was SD card death. I'd hate to rely on that for a NAS.

The 12V/5A power supply seems a little undersized for 4 x 3.5 HDD startup. I suspect that it's fine if the drives are started sequentially but the drives will probably want to pull more than 5A if they're all starting simultaneously. Possibly something to watch out for.5A should be plenty for normal post-start operation.
