I don't know how functional their solutions are
and I've never had any
of
their products nor I have anything to do with them, but I've had this
link: <http://www.arstech.com/> in my bookmarks just in case since
2005.
I guess if they have been in that business for so long now, they must
have
been doing things right.
I can tell you for a fact that they do NOT support DMA so a non-starter for
many things.....
