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.
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.
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.
@@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. ;)
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)
Buy a high quality Seasonic PSU and return whatever cheapo you bought. Add a little extra power budget for future upgrades. You won't regret it...but you might regret a cheap PSU when it takes out your motherboard and drives. I usually run high quality power supplies for about 15 years (multiple builds) before I move them to less critical platforms. Mostly due to fear that the capacitors will dry/leak. The upfront investment is worth it for the lifespan you will get. I can't say the same for cheap PSUs.
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.
That's a premium titanium class psu. You don't get titanium efficiency without using quality components. I would put that toe-to-toe with an equivalent Seasonic.
@@TechDregs I've been through so many disasters with "other" brands that I don't even think I've considered them. I generally don't mess with success. Lol. I used to build computers for people in an area where brownouts and lightning was common, and the only PSUs that didn't fail were Seasonic. 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.

It was a 37.6GB video file, which is larger even than the amount of RAM I have on the server (32GB). That's what's so odd about it.
