https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D222377 Warner Losh <imp@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |imp@FreeBSD.org --- Comment #6 from Warner Losh <imp@FreeBSD.org> --- it depends on the nvme drive. nvme works better at 4k because the dma interfaces are optimized for 4k pages. Both nvme and ssds really want to write 4k these days (they are either 4k native, or 4k native 512 emulated). And there's newer drives that want this= to be 16k (4k emulated 16k native). --=20 You are receiving this mail because: You are the assignee for the bug.=
