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. :bash: ) 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? |

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

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... |
