a laptop
instead as I need to bring it along when travelling. Downside to
laptop-as-server today is a noticable absence of SATA extra ports
or other
high speed / cheap disk attachments.
USB or FW400 is of course available, but way slower than the built
in SATA
disk. And then I suddenly noticed that eSATA expresscard thingies are
beginning to appear (Belkin has one, as does someone called "LYCOM"
as well
as "SUNIX"), and that ought to be excactly what I want.
Has anyone ever tried one of these? Is there any hope of this "just
working" because we support a bunch of SATA controllers and the
rest is
just PCI-Express?
Most of these cards are probably using a Silicon Image SiI3531 or
SiI3132,
or a Jmicron AHCI controller. The SiI chips have a forthcoming
driver.
AHCI is already supported by ahcisata(4).
