So, I saw this build here in this forum and I slept over it and my conclusion is, I want to do it like this. With a NanoPi M4 and SATA-hat.
But, I have some question, it is smart to use a SD-card for the OS, because there is an option to use a eMMC Module and frauhottelmann is using a SSD instead.
What is smarter a 2GB or 4GB board? I would use OMV, in Docker: Home Assistant with all my Plugins, Plex, Nextcloud and what the future is bringing
There is a NanoPi M4v2, this one got 4GB LPDDR4 Ram and coast 5$ less than a v1 4GB, when it comes to a 4GB board, is this the right choice?
Thanks for the idea and the help
for a NAS the 4GB NanoPi M4 is not mandatory. I own myself the 4GB version and even under heavy load the NanoPi is quite bored. I can not exactly tell you how much it is in average but I checked once while saving a huge amount of files and the CPU was around 20%...
The SATA hat in my case is different. Even if there is a heatsink on the controller IC it get´s really hot which propably is influenced by the onboard voltage regulator...
I didn´t dive deep into this by now. So you need an active cooling or a much bigger heatsink for it.
All in all my nanopi is doing a great job and is really on the lower barrier of consumption. 6.9W constant consumption while the drives are spun down is in my opinion a value which is hard to brake in this category of SBC´s and the connections the NanoPi is providing.
Regarding the SSD EMMC question. I use at my setup only a SD card. Maybe I will upgrade one day to the EMMC but for now it´s doing a great job. If you choosing the SD setup be sure to take a fast one and quality card...
