Back in the day I used a raspberry pi 3 for 1080p h.264 and steam link / moonlight. Problem was omxplayer plays up to 1080p60 beautifully, but anything else would struggle. Eventually 'upgraded' to an old laptop to easily YouTube/netflix in the browser too.

I fucking love copyparty. It starts simple enough but then the millions of options and configs let you twist it into exactly what you need.

As someone that runs a server OS that doesn't support docker, it is very refreshing to see a single binary project. It has a focus on being administrator friendly thats really fallen out of fashion these days.

Yeah true the index headset wasn't a bargain compared to the quests that were clearly being sold as cheaply as possible.

I think it would be fine. Friend of mine has Immich on a N100, like you mentioned, the initial ML tasks on a big library takes over 24 hours but once it's done it doesn't need much. I don't have experience running next cloud but the others you mentioned don't need much RAM/CPU.

ZFS doesn't need much RAM, especially for a two disk 4TB mirror. It soaks up free RAM to use as a cache which makes people think it needs a lot. If the cache is tiny you just end up hitting the actual speed of the HDDs more often, which sounds within your expectations. I dare say you could get by with 8 GB, but 16GB would be plenty.

I'd only point out if you're looking for it to last 10 years, a neat package like the ugreen might bite you. A more standard diy PC will have more replaceable parts. Would be bigger and more power hungry though.

Can get an 'aoostar GODY' on AliExpress for US$1000. Basically the same GPU, 16GB RAM, 512GB SSD. The steam machine has less cores and less ethernet. Though it also has a way bigger heatsink, LEDs and extra Bluetooth/valve gamepad antenna.

Comparing the deck to comparative brands, it is wayyy cheaper. I think valve are going to be aggressive on price, especially when the CPU/GPU are fairly old and meek.

That is fricking sick dude!

Ah kay, definitely not a RAM size problem then.

iostat -x 5 Will print out per drive stats every 5 seconds. The first output is an average since boot. Check all of the drives have similar values while performing a write. Might be one drive is having problems and slows everything down, hopefully unlikely if they are brand new drives.

zpool iostat -w Will print out a latency histogram. Check if any have a lot above 1s and if it's in the disk or sync queues. Here's mine with 4 HDDs in z1 working fairly happily for comparison:

The init_on_alloc=0 kernel flag I mentioned below might still be worth trying.

After some googling:

Some Linux distributions (at least Debian, Ubuntu) enable init_on_alloc option as security precaution by default. This option can help to prevent possible information leaks and make control-flow bugs that depend on uninitialized values more deterministic.

Unfortunately, it can lower ARC throughput considerably (see bug).

If you’re ready to cope with these security risks 6, you may disable it by setting init_on_alloc=0 in the GRUB kernel boot parameters.

I think it's set to 1 on Raspberry Pi OS, you set it in /boot/cmdline.txtI think.

sync=disabled will make ZFS write to disk every 5 seconds instead of when software demands it, which maybe explains your LED behavior.

Jeff Geerling found that writes with Z1 was 74 MB/sec using the Radxa Penta SATA HAT with SSDs. Any HDD should be that fast, the SATA hat is likely the bottleneck.

Are you performing writes locally, or over smb?

Can try iostat or zpool iostat to monitor drive writes and latencies, might give a clue.

How much RAM does the Pi 5 have?

Personally I think it's fallen out of fashion. For my blog I'd either use a meme or other dump picture for each post. When generated images first came out I used a few for blog posts, it was new and interesting and said "I'm interested in technology and like playing around with new things".

Nowadays I'm back on the meme pics. I feel now it's so much easier to generate images, it more says "I want to look professional but also spend no money and have no standards".

Nah bugger that. Famous actors are known by a vast majority of people. It is not normal for open source programmers to receive abuse to the level of death threats. That only happens when you get the attention of kiwi farms types.
