Is it possible to operate a SATA drive at reduced signaling rate (i.e., less
than the nominal 1.5Mb/s)? It appears not all implementations recover the
embedded clock for sync - some may use a local clock (presumably at
1.5Mb/s), and use the embedded clock to resync. Yet there's just enough
weasel wording in the actual spec to make me believe that there was an
intention to allow reduced rate signaling.
Does anyone have any experience with this?
Thanks,
