I bought a 2 bay NAS and I plan to flash it with the TrueNAS operating system. As I was reading the installation instructions I came across a section that said one of the 2 drives will have to contain the boot/UEFI partition, and can therefore be used for nothing else. Am I reading this correctly? I have 2 4TB HDDs that I plan on using in both bays and I’ll have to use the entirety of one of those bays just to hold a small boot partition and nothing else?
There are also 4 slots available for M.2 NVMe SSDs so I’m looking at using a small SSD for my boot partition there if this is true. My apologies if this is a dumb question as I’m kind of new to this stuff.
Heavy is relative and proprietary or FOSS has very little bearing on it. ZFS will always consume as much memory as it can.
