NVIDIA GeForce 9100 chipset advice

[Jim]

My m8's Mrs has an old HP Pavilion a6716uk which has a M2N78-LA
Motherboard which comes with the above chipset, i am having real
problems finding out information regarding the SATA sockets on the board.
I'm far from an expert but from my understanding these sockets run on
lanes and certain sockets may have more lanes (bandwidth) then others
and i want to make sure that the SSD going in is going to be on the best
port, the board has 4 sockets.

I guess i could install and run Crystal Disk Mark on each port to see
what gives best result but i'd like to know more about the chipset involved

It's absolute shite, I'm afraid (the GF9100 chipset)

http://docslide.us/documents/m2n78-la-asus-pegatron-manual-rev-3.html

says they're SATA300 ports, i.e. SATA2

Nope. Not on these. They're hanging off the everything-but-the-
kitchen-sink "GF9100" (nVidia MCP780V) chip which integrates northbridge
and southbridge.

Use the first port (marked SATA1). That means SATA port number 1, not
that it's running at SATA1 speed. Use the generic Microsoft mass
storage drivers, not the nvidia ones.

With that chipset, performance will be pretty poor, but if you're
upgrading from a HDD to an SSD, it'll still make a big difference.

Thanks Mike awesome reply, Yea it feels like it's walking through
treacle just firing up IE or FF, and she takes ages to boot to desktop,
well i'll do the work they want i'm sure any SSD will impress so
hopefully she will be happy, once again thanks for the reply.

It will.

It's not the bandwidth improvement that helps with SSDs, it's the latency.

A good SSD on the right port might give you an improvement of 4x in
bandwidth. At most.

And the latency? A 7200RPM drive is doing 120 revs per second - 1 rev in
8mS. So on average you'll have to wait half a turn for some random
sector to come around - 4mS - on top of the 5 or so to get the head on
the right track. Say 120 transfers per second. On a high-end drive. An
old 3600RPM 12mS per track is half that.

An SSD - the latency is essentially zero. Nil, rien, nada, nothing.
You'll get thousands of transfers per second. Even on a slow interface.

In the end i got a good deal on a Sandisk Extreme Pro, which is overkill
for her i know but as i say it was a decent deal so went for that in the
end.
