Icon17 Mobile Chipsets Don't Take Advantage of SSDs faster than SATA150 spec ?

The latest SSDs have surpassed the SATA-I spec and have made 2 things abundantly clear:

1. There is hardly ANY SATA-II mobile chipset out there!

The very common ICH8 provides SATA-II support, but it is not a SATA-II chipset in itself. All it means is that SATA-II HDDs will work with it...
You won't get the speed benefits of SATA-II, as I've discovered upon installing a faster than SATA-I SSD (OCZ Vertex 30GB).

Feel free to benchmark with ATTO, if you don't believe me.

Here's mine:

- A Dell 1720 laptop (ICH8M), the 30GB is the OS drive and there is another 250GB mechanical HDD.
- All tweaks have been performed (and they are a lot!) as detailed here
- The 30GB Vertex is aligned with an 128 offset.
- WinXp Pro SP3 (with all the latest updates), clean install.
- AHCI 8.7, Intel Chipset Driver 9.0.0.1008
- No other programs running in the background (not even text services or Anti-Virus).
- ATTO run of the C drive (Vertex).




2. There is no point for laptop owners to buy any SSD that exceeds the SATA-I spec!

(3. And of course that mobile chipsets are well behind the times when it comes to storage technology. )


If anyone knows of a true/actual SATA-II mobile chipset, please post a link here.

interesting find, definitely something worth looking into. Upcoming AMD/INTEL mobile platform show no change of this?

Well, there is ONE ssd enhancing chipset on the market!

The ICH9M
• Two integrated Serial ATA host controllers, each with transfer rates of up to 3 Gb/s, support four SATA ports for increased storage capacity and speed.
allegedely!

Anyone got one to confirm SATA-II perfromance?

The mobile Nehalem (Calpella / Ibex Peak-M / GM47) platform is supposed to have explicit support for non-volatile cache and SSDs. Though we won't be seeing that for some months yet.
As I'm being informed.

searching the web for http://www.google.com/search?q=mobile+chipset+SATA300 brings it to a thread of yours

Damn right! I spent 2 hours researching this last night, all while being very angry thinking that I could not even buy a laptop that could take advantage of these great new SSDs.

At least consumers will now be more aware.

As UberGerbil reports:

Quote:
AMD's SB600 is used in some mobile AMD systems and claims 3Gbps capability.
The nVidia nForce Go 430 claims this as well.
The SB600, however, is as bad as SATA-I, while the nVidia one only comes with AMD mobile CPUs...

Do any users have experience with either ICH9M or nVidia Go 430 chipstes and SSDs?

This is interesting, but not a huge surprise? Intel's mobile chipsets have lagged behind desktop by a generation or two. ICH8M is from the 965 chipset, atlhough the desktop ICH8 does support 3 GB/s support.

Intel's spec sheets do not appear to specifically mention the type of SATA spec for the mobile versions of the ICH8 family.

Indeed, I've gone through them. All there is, is a passing mention of SATA but not details as to what kind exactly.

How about nvidia's 9400 ? (Mac notebooks)

http://arstechnica.com/apple/news/20...0-chipsets.ars

Looks like these are 3Gb/s, but not sure if that's native...
