More recent testing shows the Toshiba drives hitting around 225-230MB/s transfer rates on real world large file transfers. That's more in line with what I would expect, given their 268MB/s ratings. I'll update here if/when I do some big reads. Right now I'm still moving things over to them off of other sources.
In my Rosewill 4U server I found using Arctic P8 max 80mm fans and P12 Max 120mm fans provide high CFM and can run quiet under 75% speed. Great video. Thanks for sharing.
zfs read/write will be done in RAM first, so if your test data fits in RAM, it wont even touch the the spinners until it flushes the transaction groups to disk. additionally, mirrors generally give the best performance. reads will be basically the speed of all drives added together, as ZFS will split the requests. writes will still be limited by your number of vdevs, which is one, so that'll be the speed of 1 drive.
I agree with that you said about HBA's I've dealt with them raid controllers and SAS expanders for years now. My next build will be a board that has tons of on board sata and NVME slots and biforcation support. The only reason you need this stuff is if you are going to be connecting multiple drive enclosures and most people will never get to that level.
I also have a Proxmox Server with 2 HDD's and multiple SSD's in it. And the i7-6700 is really efficient with just 23W idle, running over 50 LXC's. I love Proxmox 😅
try changing the cpu governor to powersave instead of performance on proxmox this will reduce your turbo frequency and therefore your consumption. on my server it made me go from 300w to 186w in bench
I actually did that yesterday and it maybe made half a watt of difference. After I dug into the issue, it seems the newer AMD and Intel CPUs are already super efficient scaling their frequency to the workload. Even their performance setting scales down a lot at idle.
@@TechDregs it's especially in bench that the difference is seen after it's sure that on recent cpu it feels less. on my old xeon from 2011 the difference is just impressive.
Hey! Great video and great overall power comsuption and noise from that system, that I suppose is going to be your 24/7 NAS/home server. What about the drive cages? Do they come with the Roswell? Are you using an HBA and which one? About the online file server, that is an extremely good idea, but that deserves another video. I think that for this build it'll be ok to passthrough the drives to some solution like trueNas or Unraid and exposing some directories in them to an SMB with portforwarding. At the most, use ftp and that's it. The Filestash thing is really overkill for just one video and deserves its own. Keep the good work, my friend.
Yeah, the drive cages are included. No HBA card; that's part of why I went with this MOBO. It has 8 sata ports. Filestash is actually very lightweight, and allows for drag and drop uploads and filesharing. I can make a video on getting it set up, but honestly, when I do those more technical videos, very few people usually watch them. LOL.
Thanks for the video - I'm planning to upgrade my server next year, and will be going down a power efficiency rabbit hole... was already leaning towards Intel because of the (apparently) lower idle consumption and iGPU transcoding support, but it looks like I'll still need to do a bunch of research 😅 I considered moving my Home Assistant to a VM on my server, but ultimately decided to get a Home Assistant Yellow instead. Whether that makes sense obviously depends on your usecase :) - but for me it means the automations keep running if I need to do maintenance on the server, and since the heaviest thing I run on HA is ESPHome builds, a CM4 has enough computer power, and eMMC storage is a lot more stable than doing a janky setup on a regular Raspberry Pi with SD-cards or (horror!) USB attached storage. The Yellow also has built-in Zigbee and NVMe support, so you can get even faster / more reliable storage than the compute module eMMC. Oh, and the Yellow should also support the new version 5 compute modules, for even more compute juice.
Yeah honestly the main thing I'm eyeballing with moving HA over is how it improves voice assist. However, that's more of a curiosity than anything. I don't actually use voice assist much (kind of like Jeff Geerling's last video on HA voice hardware). But the possibility of throwing a real GPU at it and getting lightning fast high quality voice responses is very tempting.
Yeah, that's a big gotcha. I selected this board in part because it doesn't have that issue. You can load up all the M.2 and SATA slots, and the PCIE lanes aren't shared.
@@TechDregs after finishing the video I'm less certain - it would explain reads but not writes. I was only half watching the video too - no offence. ;)
ARC is “built-in” with ZFS. You just need RAM.

One advantages on AMD platform ： 4/4/4/4 pcie bifurcation Intel ： we try everything to lock up features variety from pcie bifurcation, voltage and multiplier setting, overclock etc 😂 But if you need transcode encode decode go Intel for sure Possible good option ： AMD 4004 eypc which was on am5 and officially supported ECC memory with correct board
Honestly, I think one of the AMD mobile processors with their IGPU would be pretty awesome for a home server; they just aren't cheap. I've went back and forth on ECC before deciding that I just probably didn't need it.
@@TechDregs their G series is too expensive compared to what they selling on mini PC, don't go for AMD am5 G series EPYC 4004 was similar to desktop am5 ryzen 7000/9000 with a weak 610m in the IO die part, provide very basic decode encode function , which wayyyyy too far back behind compared to Intel quick sync even the one on n100/n305 But on a consumer / basic server board without IPMI a IGP is best you can have to give a little help 4004 start from 4 cores to 16 cores so it just like a budget server version of ryzen (like Intel Xeon on consumer platform before Intel chop them down)

Nice build and thanks for sharing. Any thoughts on what would you improve or do differently after all this? You learnt about ASRock not going higher with the C states. Any thoughts on what would be a better choice when it comes to MB? Do you think you will use that power? Storing stuff from cameras, NAS functionality, home automation can handle old i3 mini pc, or even raspberry. I can see that you are after higher transfer speeds and lots of storage possibilities. But this can be achieved in minipcs as well with a lower power consumption. Although your initial one was not bad I wonder how it increase when you move all the stuff you plan. I run my homelab on old hp elitedesk g3 and when it comes to power it is still a beast for all the mentioned tasks. I run proxmox with 4 VM and more than 10 docker stuff. Considering change because of the case that is just too small to hold all the disks in one box. And also for fun. However not decided yet because currently my idle is under 10W and power consumption is important to me. I think processor are quite power efficient at idle these days so are easier to pick for Homelab than MB that would meet your expectations and not much more, run at high C states, not to mention ECC topic. :)
Other than perhaps finding a different motherboard, IDK. The thing with the motherboards is, I'd probably need to reduce the SATA ports and just add an HBA later if I really ended up need it, because there are very few boards with 8 SATA ports. I haven't researched specific boards though. As far as mini PCs and RPis, none of them can really do everything I'm doing. They lack I/O bandwidth, ports, and bays. Something like the Minisforum MS-01 looks neat, but costs almost as much, doesn't have drive bays, and has pretty much the same idle power draw. An RPi couldn't even run my NIC.
When you were writing to the Toshiba drives, did you copy more than 512 megabytes? The technical spec sheet explicitly lists a 512 megabyte buffer that will most likely operate at or close to SATA 3 speeds, which is what you seem to be getting. This also means that anytime you're copying stuff that doesn't overload the 512 megabyte buffer, you'll continue to get those kinds of speeds - and the buffer will probably clear out at or close to HDD speeds, so you'd probably have to copy more than a gigabyte before it slows down.
@@TechDregs Thanks for revealing the "secret" of how much RAM you put in this rig 😂 Thanks for the tip on the idle power of that CPU - a great choice. Your analogy to a WWI soldier in the trenches was a little distasteful… all that time "hanging around" I'm pretty sure soldiers were spending it terrified and worrying over if they'd live another day. I'm sure you didn't mean it to come across that way though but please be mindful in future.

Don't put all your eggs in one basket..... if your CCTV system is an important piece of your security system, leave it on it's own dedicated piece of hardware (with a UPS) And then sync it to your NAS so you have two copies of the video...although you probably want to dedicate a drive or two just for this, and have it write over itself.
My NVR uses dedicated drives that are already mirrored. I'm just going to move those over, so everything will be kept separate other than the processing. UPS back up requires powering the cameras as well, so it takes a pretty decent system to keep them up in a power outage. I'm looking into that for a "maybe next year" thing.
I'm trying to find a cheap NAS...I don't need high performance. If a RasPi can handle 6 to 10 or more drives, I'll go with that. If an old M1 Mac Mini can handle 12 drives, I'll go with that....which is what I'm pondering. I want LOW energy use
For 6-10 drives, your drives will draw more power than the rest of the computer. The trick will also be finding something that can attach more than 6 drives. You'll want to pay attention to how many ports are available, what kind, and if it has PCIE slots (so you could add an HBA). You also want to consider what sort of networking you want. Is GbE enough or do you want higher bandwidth. I think they make some N100 motherboards that have 6 SATA ports. If you're looking for just the cheapest and lowest power platform possible, I'd probably check those out.
For other people thinking to get one, this is a pretty bad build for a NAS in general. NAS can work on anything, in fact the basic one from Synology have ARM CPU, and people DIY NAS even with raspberry. You can run a NAS with a ton of dockers and some VMs on a 4 threads CPU and 8GB of ram without sweating. So the first issue is the overkill CPU, then the motherboard, that's a gaming MB, that mean having a lot of useless stuff, like Wi-Fi, extra I/O, fancy audio card, RGB and mostly a lot of VRM and phases that consume a lot of power, switching constantly. The PSU is a big nono, for a system that can idle at 10/15W and max out at 50W, there is no need for a 800W PSU, get the smallest one, generally around 300/400W. Good hardware suggestion is, N100 system or something with a G7400. If you really want to go big as power, an i3 12100 is fine, avoid 13/14 gen and mostly avoid AMD.
Well, I built a server. NAS is just one function it serves. An N100 system will draw around 9-10w at idle running HAOS with a couple of SSDs. I know, because I have one. My server pulls 15-17w in the same state (potentially less if you can get above C3). As far as the MOBO, it does have features that I don't use, but many of them can be turned off, so they don't consume power. Thus, the idle power draw isn't that crazy. The PSU, I agree, is larger than necessary. However, there are some issues with your suggestion. They don't make many 300-400w ATX Titanium rated PSUs; and anything more than Bronze rated isn't much cheaper than what I bought. Even then, the power savings are minimal. Yes, the percentage efficiency would be higher, but since the load at idle is very low, the absolute power saving is only 1 to 2w most of the time. The other thing I'm keeping an eye on is future expansion, such as adding a GPU for local LLM or voice processing for Home Assistant. That will increase the power draw, and I won't have to worry if I want to go that route. So, sure, if you're just doing a NAS, you would be fine with a much lighter machine. However, the power differential for a N100 system is probably less than 10w at idle.

I look at them. They are quite expensive. The Leadex isn't cheaply constructed. Superflower has a pretty decent reputation for reliability. But yeah, Seasonic is the gold standard.

@@iwh7 _"which spinning disc nas has 10W consumption?"_ My ARM based RAID1 NAS with 2x1TB HDDs takes 15W *maximum* from the grid, and this data is not based just on an assumption made from reading datasheets or somebody else's anecdotes in the Internet but actual measurement done with an Amp meter at the mains. And it doesn't need to fall into a "idle mode" to achieve that. The $27 of annual electricity bill is what adds to & defines the *actual cost* of my home server.
Remember that when you screw that thing into an UPS for power backup you'll likely end up doubling the power comsumption. But 10 to 15 W for a multi HDD NAS is unrealistic. Most HDD will pull 8 to 10W each by themselves.

After some preliminary research, maybe I'll give them a try for something. That said, if the price difference between a Seasonic and the next best PSU is $100 or less, I'm probably gonna go Seasonic. If you consider the long-term investment, that $100 is peanuts IMO.
@@RK-kn1ud Superflower is an OEM like Seasonic. They are known to build really high quality power supplies, they're just usually branded by other companies.
Superflower produces quality PSUs, I've run that exact PSU in my server and workstation for 4 years without a hitch
why not intel xeon
Cost/performance. You have to go used Xeons or you have to drop a lot of money. Plus I get an igpu, which could come in useful.
just use a pi instead, 99% lighter, cuter, slower but thats fine
NIC = Network Interface Card. No need to say NIC card.
It stands for network interface controller. That's why you can have an onboard NIC, which isn't a card.
@@TechDregs card and controller are interchangeable when talking about NIC's 🤷♂ it's an acronym...
The efficient home NAS & server is when it consumes 10-15W max. Whatever above is not efficient.
What do you expect from a 13th gen Intel CPU? And 10-15W vs 25W idle isn't much of a difference.
which spinning disc nas has 10W consumption?
Yeah, these two HDDs are close to 9W at idle by themselves.
@@iwh7 _"which spinning disc nas has 10W consumption?"_
My ARM based RAID1 NAS with 2x1TB HDDs takes 15W *maximum* from the grid, and this data is not based just on an assumption made from reading datasheets or somebody else's anecdotes in the Internet but actual measurement done with an Amp meter at the mains. And it doesn't need to fall into a "idle mode" to achieve that. The $27 of annual electricity bill is what adds to & defines the *actual cost* of my home server.
Remember that when you screw that thing into an UPS for power backup you'll likely end up doubling the power comsumption. But 10 to 15 W for a multi HDD NAS is unrealistic. Most HDD will pull 8 to 10W each by themselves.
