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?

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

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.
