A low-end x86 CPU will perform better than the RasPis. My current NAS is an Intel G4560 with 40GB of RAM and 4 HDD and it barely does over ~40W on average. The article's cluster does 18W which is better, but even over a year that's only a 192kWh difference (assuming that is runs all the time) which would amount to about 40$ at $0.20/kWh.
It's not really worth comparing further as the configuration are significantly different, but if your goal is doing 110MB/s R/W, even when accounting for power consumption the product in the article is much more expensive.
- pbhjpbhj 4y agoI don't know much about NAS and thought they were just a bundle of drives with some [media] access related apps on a longer cable ... 40G RAM? What's that for, is it normal for a NAS to be so loaded? I was looking at NAS and people were talking about 1G as being standard (which conversely seemed really low). G4560 suggests you're not processing much, is the NAS caching a lot?
- belval 4y ago40G is purely overkill and is not utilized. Initial build had 8G and then I had 32G lying around so I added it. 4G is probably enough. Though nextcloud does use a lot of memory for miniature generation. As for the G4560, I can stream 1080p with jellyfin so it packs a surprising punch for it's power envelope.
- formerly_proven 4y agoEven for mainsteam x86 Intel chips idle power consumption is mostly down to peripherals, power supply (if you build a small NAS that idles on 2-3 W on the 12 V rail and can't pull more than 50 W, don't use a 650 W PSU), cooling fans, and whether someone forgot to enable power management.
- SparkyMcUnicorn 4y agoThe HP 290 idles around 10W. Picked one up off craigslist for ~$50 and use it as a plex transcoder since it has QuickSync and can simultaneously transcode around 20 streams of 1080p content.
