$ But I have a more technical question... Will it be possible for the
$ SATA serial interface to keep up with future data transfer rates?

The expectation is that SATA will keep up for 10-15 years. Discussions
center around upgrades to 3Gbps (300MBps) and 6Gbps (600MBps).

We
$ all know how well serial interfaces scale up to faster data rates -
$ we have some wonderful examples: USB/USB-2, 1394, and others. These
$ examples show that they don't scale up - the serial interface either
$ is redesigned to go faster (USB/USB-2) or it just doesn't work
$ (1394). What happens when ATA/ATAPI/SATA devices need data transfer
$ rates of 1000MByte/second? That translates to a serial interface data
$ rate of about 10Gbit. How compatible will such devices be with
$ current SATA implementations. More important, will today's SATA
$ device be able to work on the future faster SATA interface?

Future SATA is intended to be backwards compatible with SATA I.

$
$ OK, of course I'm trying to stir up trouble. Yea, PATA will never go
$ any faster than the current 100Mbyte rate - PATA is dead. Yea, today
$ SATA can probably go a little faster than that. But is SATA just
$ another "dead end" serial interface thing designed by a secret
$ society only to promote the greedy needs of a few companies? When
$ will the next secret society that will define the SATA replacement
$ get started?

But Hale, greed is good. Haven't you heard? Capitalism and free enterprise
has triumphed! :-) Is everything always going to work perfectly. Nope.
That's why we have consultants. $
