We make them, and our customers use them. 14 drive building blocks,
which combine into groups for bigger configurations (more space, more
speed). 4 unit groups (16 TB) are common. We have run internal tests
quite a lot larger than that.

Some people would like you to believe that iSCSI and SATA are only for
the low end. Don't believe them, it's not true.
