August 9, 20232 yr Hello guys, coming from Synology world, where I had until now: DS1515 (4core 1.4Gbhz AL314, 2048MB RAM, 4x1Gbit as BOND), 3x10TB Seagate IronWolf, no SSD cache. After decade with multiple Synology boxes, I decided that now is time for DIY NAS with Unraid on top. And now question is coming. I want use new NAS as storage (like now) and for Docker and maybe few VMs. I planned to buy 4x12TB Seagate IronWolf and 1xM2 NVMe 1TB for Docker/VM purpose. Now I watched several tutorials about array/pool creation and I am a bit confused which setup should I make: - array with 4x12TB and use NVMe for cache (in this case better to have 2 for mirror seems like) => is it possible to force Docker/VM to stay only withing NVMe to not have SATA disks all time up? (I will have there HomeAssistant container which will run 24x7) - or should I have different setup like 1 array (4x12TB) with 1xNVMe cache for main and second array (1xNVMe) for Docker/VM - or should I even consider to have cache when I will have again just 4x1Gbit network card in bond (I lived last 10 years without SSD cache )? Thanks for your opinions and sorry in advance for maybe stupid questions

Thanks for your opinions and sorry in advance for maybe stupid questions I think you are thinking of cache the wrong way. Cache in unraid is just storage. Just typically SSDs so its faster. Docker/VMs happily stay on cache and recommended to be there. Ignoring specific requirements most users will be all spinning disks on array and SSDs on cache.
