Hi, =

=
=20
Normally when making an array, I'd like to use all disks all same speed, =
=20
interface, make and model but from different batches. In this case, I've no=
=20
choice, so we have multiple 1TB disks some 7.2k some 5.4k. I've not mixed =
=20
them like this before. =
=20
=
=20
What effect would this have on the final array? Slower than if all one or t=
he other? =20
No effect? I'm expecting the fastest access will be that of the slowest vde=
v. =20
=
=20
Similarly some disks block size is 512b logical/512b physical, others are 5=
12b =20
logical/4096 physical, still others are 4096/4096. Any effect of =
=20
mixing hardware? I understand zfs sets its own blocksize. =
=20
=
=20
thanks, =
