They just work.

What are the symptoms? There may be simply memory management issues for

That's very odd. Our buildd daemons typically get several MiB/sec from
the Internet. Do you have KVM really enabled?

SATA won't be better: the protocol is the same, only the channel is
different.

That's most probably rather issues in memory management or ext2fs. How
much memory did you give to the VM?
(I'm surprised to see such reports, when buildds do go fine for days
long installing/removing software)
