> - If you are thinking of ZFS/TrueNAS because of the scrubbing functionality, RAID1 + BTRFS also have scrubbing. In my experience, BTRFS is to be avoided. It's the only FS that I've lost data to.
Same here, so I had to overcome this fear. But to be fair, my incident was >10 years back, and I was trying to be fancy (resizing a live FS - IIRC). Btrfs has gone a long way since then, and is even the standard filesystem for Synology NAS boxes.
Same here, repeatedly. I've never had a BTRFS fs that didn't spontaneously combust before it would have been decommissioned. Recovery or even check is always impossible. Only things that have caused more loss were (old) XFS on Linux that ate files every power outage and ReiserFS which also blew up in an unfixable way. I'll always recommend staying away from them. A filesystem should always have reliability and no loss, particularly no invisible loss, as its top priority.
I have one btrfs going at the moment. Nothing important, naturally. Just a Silverblue test installation. Will see how that fares.

It impacts the buyer experience. These two statements have a very different impact: 1. I love product X and I won't get paid if you buy it too. 2. I love product X and I will get paid if you buy it too. Money motivates people to claim they love a product or that a product is good, even if not true. It's a problem that has plagued the internet for decades.
I don't think it's this binary. Influence and power are far more intoxicating currencies than affiliate revenue. And if someone complained "you're just publishing this helpful thing to become more influential in [community]," well, at some point we need to acknowledge incentives drive all behavior in one way or another. Refusing the incentive doesn't make one per se virtuous.
This thread is missing an important detail:
> undisclosed affiliate links.
That's quite controversial, compared to disclosed affiliate links. IMO for good reason.

#274Holy smokes, the NAS in idle consumes more power than my UNAS Pro with 4x8TB HDD and 2X8TB SSD, as well as a Mac mini M1 with a 2TB Samsung T7 SSD, and my 4 access points and 4 protect cameras combined. For reference, the UNAS Pro comes with 10G networking, and will deliver roughly 500MB/s from a 4 HDD RAID5 array, and close to 1GB/s from the SSDs (which it never gets a chance to do, as I use them for photos/document…

96W is what's reported at the wall including everything. The switch reports 36W PoE consumption The Mac Mini is 5-6W, and the UNAS Pro around 35W with drives (4xHDD, 2xSSD).
So ~75W in total for everything PoE, Mac Mini and UNAS Pro. I was 8.5W over, so remove the Mac Mini from the equation.
The rest of the consumption (21W) is made up of a UDM Pro with a 4TB WD Red, USW Pro Max 16 POE, Hue Bridge, Tado Bridge, Homey Pro, and a Unifi UPS Tower.
and yes, that's at idle (drives spinning). It does rise to 120-130W when everything is doing "something".

The loss of your vacation photos will be less of your worries
Honestly for many people that is probably not true as long as everyone is safe. Most things are replaceable, but those photographs probably are not.
Yes. Photos are often the most irreplaceable non-living thing that many people accumulate. How valuable they are does vary, but for many there will be at least some that are priceless.

"I was 8.5W over"
As I suspected :-) Also note that by measuring "36W POE consumption" you are excluding the AC-DC conversion losses from the switch's PSU which further makes the comparison a bit unfair. IOW your POE equipment draws more than 36W at the wall.
The only fair comparison is looking as only your NAS idling with drives (35W you claim, and I still believe it's closer to 40W) vs the OP's NAS with 4 drives (which should be 57W, or 67W minus 10W for his two extra drives). Then if the OP used a better sized PSU he might cut out another 10W or so (see my "PS" above) then you are comparing your 35W (or 40W) with his 47W which of course is still in your favor and a testament that Ubiquiti did a great job optimizing the UNAS Pro. But this 12W (or 7W) difference hardly matters for someone running a single NAS at their house. This extra power is around $1 or $2 monthly at average US domestic electricity rates.

#277I wanted to join the NAS club for so long but it was always either bang for buck for prebuilts ($1k for 4 bays, with 4Gb RAM and the CPU is slower than my previous phone?!) or lack of availability for 4+ SATA boards. Last year I had aha moment when I learned about SAS boards. My final build was: - Jonsbo N3 case - ITX PSU - ASRock B550M/ITX - Ryzen 5500GT - LSI 9207-8i - 16GB DDR4 Result - for ~$1k I have 8 bay NAS t…
What is Ryzen adding here towards the NAS part of this system? Or is it only for gaming?

260 Euros in Germany. And this heat also has to be moved out
Well that’s on you for living in the failed state of Germany, where power is 3-4x as expensive as it is in sensible countries like the US.
You mean the USA right?
After all the USA produces tones of co2, ignores all responsibililties in the world since trump (defunding USAID) and lets not talk about income inequality?
But hey, im pretty sure your cheap energy prices will keep inflation low and living standards high.
Btw. China took over the industry products export 2018 and since 2024 chinese companies primarily buy chines made machines.
The main problem of germany is not energy, its def one topic, but its the market force of a country like china who is huge, has a ton of resources, less worker rights, high work attitude.
China is getting rich now from the same thing which made USA big in the 60is and kept germany high until now.
We are still the 3th biggest country by gdp.
Edit: And germany is so anti innovation its not funny anymore. Even the slow car makers started pushing EVs but then everyone else said "NOOOO". Heat pump? Industry said "yeah ready" and then everyone else "NOOOOO".
While this happend in Germany, in China EVs are normal already...

So you buy used enterprise disks because their error detection is 'better'? Do you have any source for this claim? Why would be the firmware so different? Software is cheap i don't think they would be that different. I mean a used enterprise disk gets sold after it was running on heavy load for a long time. Any consumer hdd will have a lot less runtime than enterprise disks.
The protocol is better (SAS). Once I put them in, I immediately noticed transmission issues in a counter going up for several of my HDDs where the SATA showed no errors at all. It was a faulty backplane that introduced these transmission issues that went unnoticed by my SATA drives for several years.
Could you elaborate?
Did your HDDs then wrote broken data?
Do you use ZFS? I think that should have indicated some HDD issues independent of a counter by transferspeed or something like this.
Not that the backplane was just not good in handling SAS?

"by measuring "36W POE consumption" you are excluding the AC-DC conversion losses from the switch's PSU which further makes the comparison a bit unfair. IOW your POE equipment draws more than 36W at the wall."
I'm aware of that, but the wall measurement is still 96W before the UPS, so it's basically just pushing numbers around the same budget. The switch is the only place i have to measure "poe power consumption", so i quoted that number.
"35W you claim, and I still believe it's closer to 40W"
I have 4 x 8TB WD Red Plus drives in there, quoted by WD to be consuming 3.4W idle, so 4x3.4 = 13.6W, and a couple of Samsung QVO 8TB drives, which idles at ~45mW. Assuming the UNAS pulls 20W by itself, adding the drives lands us at 33.7W, right in the ballpark of my measured 35W.
Part of my "astonishment" was also that i run my entire "infrastructure" for 30W more than OPs NAS idles at (66.7W vs 96W).
And yes, 7W is probably peanuts, but when you're paying €0.35/kWh, it all adds up. I came from a full self hosted setup, proxmox, multiple NAS boxes, etc, and was using ~350W idle, when power spiked in 2022 to €$1.12/kWh (peak pricing, 17-21, with an average price some days of €1/kWh). I initially turned everything off, and with just the Mac mini, router, switch, APs, cameras, various hubs, i was at 67W.
The UNAS has been added since (after power prices stabilized), which took the idle power consumption to 96W. And no, the UNAS is not pulling 29W. I've removed a couple of cameras, replaced a couple of APs, even removed an AP, so it's not direct comparison, other than in terms of total power consumption for price comparison.
