Hi,
my oi151 based home NAS is approaching a frightening drive space level. Right
now the data volume is a 4*1TB Raid-Z1, 3 1/2 local disks individually
connected to an 8 port LSI 6Gbit controller.
So I can either exchange the disks one by one with autoexpand, use 2-4 TB disks
and be happy.

unclear about the 512b vs 4Kb issue. What sata disk could I use that is big
enough and still uses 512b? I know about the discussion about the

Hi Tim,
thanks to you and the others for answering.

Hi Tim,
you might be able to use
an adapter to the SFF-8088 external 4 lane SAS connector, which may
increase your options.
So what you are saying is that something like this will do the trick?

Good to know. This really opens up the

No problem, and yes, I think that should work. One thing to keep in

the multilane SAS cable into 4 connectors without an expander, and you
use SATA drives, the controller will use
