Does eSATAp support SATA 6.0?

If I buy a SATA 6.0 hard disk and plug it into the eSATAp port, would
the drive slow down to SATA 3.0 standard?

An eSATAp port can be any 1.5, 3, 6 Gbit/s, depending on the mobo.

A SATA 6Gbit/s hdd is (should be) backward compatible with 3Gbit/s mobo
('slow down' less bandwidth).

(But) There are 1.5Gbit/s mobo/s (chipsets) that won't be compatible
with a 3Gbit/s hdd unless it can be configured to be 1.5Gbit/s speed.

As I read the wiki on the subject.

The two ends of the link, work at the highest common rate they support.

That holds true, unless one end fails to negotiate properly. In which
case, using a jumper plug on the device on the other end, may be necessary
to build a working link. That shouldn't happen with modern interfaces.
Even VIA figured out how to make it work, when they delivered the
VT8237S. That chip has a fix for the negotiation problem.

For hard drives (rotating platter), not much is really "slowing down",
because the head to media rate currently sustains around 130MB/sec. And
SATA II handles that with ease. Putting SATA III on a hard drive, doesn't
serve much of a purpose (except as a "shiny marketing bullet" for the advert).

SATA III is good on an SSD (flash drive), as if you put enough channels
on a flash drive, the bandwidth can be high enough to make good use
of SATA III. But if you read the reviews here, you might think twice
before buying one.

If you were talking about a direct SATA-to-eSATA cable, it might give
you 6Gbps.
