Intel AHCI Driver Question

Thanks in advance!

Okay, which driver should I use for AHCI capabilities, the driver that is installed via the intel chipset utility, or should I install the newly updated "storage matrix" driver and software?

I only have one HDD and care not for raid despite my SB being an ICH9R.

My gut tells me I'm fine with the driver that comes with the intel chipset software, but I just wanted to be safe. Any insight would be deeply appreciated.

Thanks!

Windows 7 X64 Ultimate
Intel Core 2 Duo E8400
Asus Maximus Formula X38 chipset
1 WD Caviar Black Edition 1TB HDD
4GB Gskill DDR-2 800
BFG Tech GeForce 8800 GTS OC2

"Storage Matrix" is Intel marketspeak for RAID. Use the standard chipset driver - the one built into Windows 7 will work just fine.

Thanks for the reply, sminlal! = )

I just searched Intel's download site and found the now called, Rapid Storage Technology has a much more recent driver for my AHCI than the regular chipset software does.

According to the release notes, it claims that the RST is needed for AHCI to work. I understand Windows has a built in AHCI driver, however, is it not best to go with Intel's?

Again, any insight would be deeply appreciated.

Thanks!

I just used the driver included with Windows and haven't had any issues. I've not heard of any problems with the standard AHCI driver and if you're not looking for some specific feature in a later version my inclination would be to just go with the one on the Windows disc. This is because I'm an "if it ain't broke, don't fix it" kind of guy.

It would a different story if you're using RAID HDDs with an SSD, since Intel has a new RAID driver that will pass TRIM commands to a single SSD when the chipset is in RAID mode. In that case I'd go with the latest Intel driver.

Hello Everybody,

I have a laptop with Intel 915 chipset, bought an SSD, put Win7 on it.
The performance seems to me very slow.

http://www.photofast.tw/products/ssd-idev3.html

Read: 92 MB/s
Write: 46 MB/s

Can somebody please help me solve the problem?
Is there any AHCI for ICH6M? Or any other Intel driver?

^Wow, those speed are over/almost half of what Intels speeds are spec'd at: 230MBps Read, 70MBps Writes. OCZ Vertex 2's are listed even faster.

Also, that is close to what the website had listed, just a little slower. These speeds are even slower than my HDD.

Is it too late to return this SSD, and say get a Intel X25-M 80GB for $229.00? Or any other SSD: OCZ Vertex, OCZ Vertex 2, A-Data X25-M?

My SSD is using IDE not SATA!

Ah, then I think they are good.

Sorry, I didn't know they made SSD for IDE. I should have read the link better.

My bad!
