It would be very helpful to know how closely the identifier string needs to be to what format(1m) reports.  As I read things, it should be the concatenation of the Vendor & Product strings. I tried to copy it exactly, but have no clue if it read it correctly or just silently ignored it.

Are you going to be using ZFS on those? If so, how does the ashift of a
zpool created with them look like?

# zdb <poolname> | grep ashift

If it prints "ashift: 12", then you are good, zpool picked up the
correct settings.
