Does the Envy 17 have Port Multiplier for eSATA? [ Edited ]

[Fireater989]

I'm looking at buying a multiple bay drive enclosure like this or this. They both support USB or eSATA host connections, but naturally you get faster speeds with eSATA, but for the computer to recognize all drives, it says I need to have Port Multiplier. I've looked and looked and looked and can't really find anywhere that says whether the 17 does or doesn't. I'd also rather have a software controller rather than a hardware. Any help?

Edit: It has to be a FIS-based switching PM also

I don't know of any HP notebook with a e-sata port multiplier, you are better off to go with USB 3.0, its faster.

eSATA III is actually faster than USB 3.0, and that's assuming the enclosure I'm buying even has USB 3.0. On top of that, 3.0 doesn't even have that great of transfer speed. The fastest write I've had with my external HDD is around 90 Mb/s
