If you care about Sata3 interfaces, the Odroid HC4 has two of them with vertical disk holders. https://wiki.odroid.com/odroid-hc4/odroid-hc4 The one I'm using as home server is consuming 3.48 W now with a Samsung 850 SSD (1 TB.)

I like the specs on the HC4 but that form factor just invites passersby to yank out the drives.

A home server should not be concerned with passersbys.

What speed can you get over ssh to that board? The big issue I had with the Raspberry Pi 4 when using it as a low-powered server is when I run my backups to it over ssh, the network transfers top out at about 20 MB/s (just raw transfer speed going to /dev/null) vs. around 100MB/s I get on a regular x86 board.

I benchmarked it right now by copying a 6.1 GB file with scp from my laptop to the HC4 SSD. It eventually peaked between 77 and 80 MB/s (that's a B for bytes.) I have a 1 Gigabit interface and a 10 Gb/s cable so it reasonably saturated the interface. There were maybe another 10 or 20 MB/s to squeeze from it but I won't complain. It took 1m 13s.

2nd hand laptops like those X and T series easily beat this server with some RAM and SSD upgrades. I got T430 i3 and i5 for around 150 dollars a piece. I dont see the needs of Zima unless you really prefer new crippled compute. Even using Zulu or Rp5 or Op5 make more sense than Zima.

I've run the T430 as a server and it's faster, and a lot louder as well. That's the trade-off.

> "I suspect that a similarily configured Raspberry Pi 4/5 with all the accessories added on top would result in a price that’s quite similar to the cost of a top-of-the-line Zimaboard." With respect to the author, why would you not take 10 seconds to verify this claim? A cursory Google search shows that an 8 GB Pi 4 with passive case and PSU is ~$100 all-in. If you can wait a couple of weeks the Pi 5 offers a nice p…

> This variant of the board costs 200 USD ... Doesn't sound like a good deal when compared with 2nd hand microservers and small form factor PCs from Ebay. Things like these: ∙ https://www.ebay.com/itm/175917817224 ⇦ 2x NVMe slots ∙ https://www.ebay.com/itm/204477355543 ⇦ 4x 3.5" drives, ECC memory capable Note - I don't know those sellers.

You can’t compare used products with brand new ones. You should compare with a used zimaboard market price.

Yeah, you can when we're talking about home servers.

There’s also the upcoming Zima Blade that is very tiny too, quite a bit cheaper, with a SO-DIMM slot, single Ethernet port, and USB-C powered.

The Zima Blade isn't actually USB-C powered - it's just a USB-C port carrying a raw 12V. No PD negotiation supported.

Honestly, for me, total dealbreaker for a product like this. Not only will it never work with anything other than the original PSU, that PSU will likely fry anything else you plug it into.

I find NUCs kind of just work for home servers, consume a very reasonable amount of power (10W idle, 90W at full load, ~15-20W average in my case), aesthetically very neutral, and run standard Ubuntu distros with zero hardware driver issues. Everything works out of the box with a vanilla install.

They're also available dirt cheap second-hand if you're okay with a generation or two older processor, and you can use an m.2 SSD inside the case without a dangling hard drive like I see with TFA's Zimaboard setups.

I have the Gen8 microserver from your second link and what I really like about it (besides the 4 bays) is that is has ILO. Whenever there is a boot issue or I need to reinstall I don't have to drag it out of my server closet onto my desk, find a monitor and keyboard to hook it up to (now that I think about it, I don't even have a VGA monitor anymore) just do basic BIOS or GRUB stuff. It can all be handled via the web interface and the HTML5 terminal works great. Biggest downside of this machine is the power draw, even at idle.

I couldn't find anything in the Zimaboard docs about it, but my guess is I'd have to find a mini displayport compatible monitor if I ever need to do disaster recovery of the OS. This especially becomes an issue with the eMMC, as you cannot swap it out easily like an SD on a raspberry pi.

Earlier quoted context omitted.

That's why I included a 60W cost too. What's the point running hardware 24/7/365 is it's idle?

Because home servers tend to be bursty on demand workloads. If you doing something that is hammering a CPU at 100% 24/7, then you’d get a faster CPI to get the workload completed faster and you’d be back to having idle CPU cycles… Now RAM on the other hand! Free RAM is wasted RAM!

ZFS will take care of that for you.
