Ultimately, if you can move that SSD to another motherboard and test it, it would confirm where the issue is. I have often wondered if ZFS is more aggressive with discs, because until very recently any solid state drive I have used ZFS on broke very quicky. For USB sticks that is not unexpected, but decent SSD's also seem to last less than a year with ZFS on top. I don't let it bother me anymore simply always install them in pairs and replace when I start seeing errors. By the way, I am not talking about checksum errors here from ZFS, I am talking about the drive starting to error into dmesg. Checksum errors I could belive that I was gettign with UFS in the past and just didnt know it. But this behaviour is that the drive stops working. Some USB sticks lasted less than a week. Some earlier SSD's only a month or two. More recent SSD's are lasting longer, and I dont use USB sticks much anymore. I am sure I have mentioned this before and people say that it works for them, so maybe its my magic touch which causes it. :-) -pete.
