I'm using an older revision of WD10EADS drives that allow TLER to be

I've got a system running s10x_u7wos_08 with only half of the disks
provisioned. When performing a dry run of a zpool add, I'm seeing some strange

You haven't stated what you intend to use your pc for and what your
requirements are. Without that I don't see how anyone can come up with
an optimal configuration. So... what do you plan to do with your pc?
Do you want the fastest performance and don't care about anything else?

dedup doesn't replace the snapshot/clone feature for the
NFS-share-full-of-vmdk use case because there's no equivalent of
'zfs rollback'

cloning in ZFS. Based on that thread I understand that it's not currently
possible to 'clone' files instead of 'copying' them, but the

Ok, so the bandwidth will be cut in half, and some people use this
configuration. But, how bad is it to have the bandwidth cut in half? Will it
