I’ve been running a pair of BeagelBone Black SBCs for this for years. The one I just retired to replace with the current model had been running nearly continuously since 2014. (Powered down to move — twice — and for power outages here and there.) It's anecdotal, but my experience so far is that the onboard eMMC seems faster and is less corruption-prone than SD cards.

Similar story here for longevity of the BeagleBone Black. It’s as good, or better, than the matching RPi.

Just replaced my rpi with a 10th gen nuc. It’s not fanless. It’s pretty quiet and power use wise it’s sipping under 10W when idle (which is obviously most of the time). I run proxmox on it and a couple of VMs with home assistant etc.

I looked at SBCs but getting something that had a well built case and reliable passive power supply, gigabit/WiFi/Bluetooth/nvme and also manages a high peak workload (recompiling kernels etc) without breaking a sweat at ~$3-400 is hard to beat.

I have an always on HP ELITEDESK 800 G2 - I5-6500 3.20GHZ with an SSD. Uses about 20w. I recently measured power consumption over a few weeks. I unplug the monitor which saves a few watts.

I love the Pi but it is not a server. My best experience of Pi is when the Pi does one thing e.g. uses rsync/rclone to back up all my data to an encrypted usb disk.

Also, the box has built-in kvm/vnc which is handy as I need a ladder to get to it in my roofspace

Can someone explain to me the use case of a home server? I've always enjoyed tinkering with RPis, but have never found a good enough reason to keep one running 24/7 as a server. PiHole seems to be the best use case for it, but uBlock Origin or Wipr handles ad blocking for me.

Earlier quoted context omitted.

The USB storage firmware itself will do this. ¼ was chosen to give a lot of space for this wear levelling to occur; wear levelling can't use occupied space, so it'd need to move data around a lot if the drive was close to full, which would increase wear.

Wouldn't this also work with a large enough MicroSD?

As I understand it, the firmware for the majority of MicroSD cards is very limited. The physical size and low price point are likely the reason you don't see these more complex features in consumer cards. Also, if I recall, there's nothing in the spec about levelling so you'd probably get some half-arsed buggy implementation anyway.

The RPi 4 with an external USB SSD drive should last a while and the SD card won’t wear out as fast if you’re writing to the SSD plus they have more RAM on 4th gen. I have 3 that have been running 24/7 in that configuration for a year as a Kubernetes cluster and have had 0 issues.

What's your budget?

My home server is mainly a file server and automated backup server. I also use it to host dedicated servers for some games my friends and I play (minecraft, KSP dark multiplayer, halo ce, etc.). It does PiHole and steam/origin/blizzard/uplay download caching (steam game install from a bonded dual-10G server is fun) as well.

I picked up a SuperMicro mini-ITX 8 core Xeon-D based server board on eBay for ~$400. The idle power is With 6x 10 TB WD Red drives and 2 NVMe disks it pulls about 25W at idle (mostly the drives). If I wanted to run the Kodi or Plex on demand video transcoding I'd probably throw a used quadro in there (or, hack around the transcode limit on a GeForce card).

I have an old desktop running Plex, so I can stream my personal movie and TV library to any of the Roku devices in my house.

For a household with 2+ people – each with personal phone and personal laptop plus a bunch of common devices like TVs, streaming speakers etc you would need a bunch of useful local LAN services:

1. Local Backup storage server – always have a local+cloud back – neither one is good enough just by itself.

2. Local streaming service – photos, music, home videos etc.

3. Internet gateway –

a. filtering firewall,

b. privacy enhancing dns server,

c. optionally wireguard based tunneling with custom routing.

d. You can also log and catch suspicious traffic in your network (best way to catch an infected device on your home network).

e. If you have two Internet connections, you can configure them for high-availability and load-balance your outbound traffic.

4. Local software updates caching proxy.

5. Mail server (transport/relay).
