Dammit, I was trying to get away from BSD in general and FreeNAS is the only thing left.
But at least it is nice to know that it basically works and is probably getting there in the not too distant future.
I will build the system over the next week I hope. So far I just have two 500GB MX300 SSDs here and I will test with that first before sinking all the moneys into storage.
I also found the thread I was looking for with some help.
And it seems that TRIM is the last big thing that’s in the way.
… well, and NAND pricing obviously.
But it is close to where it was two years ago… yay.
