I've got some questions about what needs to be changed with an SSD pool. I've been looking around to find information about Sector size on SSDs and have been getting conflicting information about whether it matters at all. While on hard drives it seems 512 and 4 k size sector are the norm, I've seen information about huge sector sizes on SSDs. When I tried to look at the sector size of my SSD via fdisk -l I got a size of 512 bytes, Is that normal on an SSD? I also found information saying using ashift of 13 made sense on an SSD, why would that be? I know these are a lot of questions but I've been having trouble getting any consistent information about using SSD pools on ZFS. Does anyone have experience as to how to check sector size on SSDs properly and whether or not they have to be aligned with ashift?
