I have at home not 1 but 2 desktops ( and 3 kids ...)

One is an AMD config and I left the SATA controller in "IDE compatibility" mode.
I initially had done the same on the intel config.

I'm now upgrading the Intel config to add a corsair F60 SSD and upgrade the OS to windows 7. Other drives are a SATA-ii plextor DVD-RW and two Samsung sata-ii HDD ( spinpoint F3). All SATA peripherals are mounted to the ICH10 controller.

I was wondering whether it would make sense to convert to AHCI . AHCI is supposed to improve performance but aren't there issues concerning optical discs ?

And if so, should I a) simply put the controller mode on AHCI in the bios and go on with the win 7 install process or b) make the install in IDE mode and go the registry hack trick afterwards ?

Using an SATA controller in "IDE compatibility mode" all the time is just dumb: AHCI doesn't just improve performances, it gives the drive the chance to exploit advanced features like hot swapping and native command queuing.

FYI, I use the IDE compatibility mode of my SATA controller only when I have to load some boot disk that has no clue of what an SATA controller is, and I switch back the controller to AHCI mode soon afterward.

Assuming it is correctly detected by the OS (be it a PATA or an SATA drive, it doesn't matter), an optical drive has nothing to do with the AHCI (or IDE compatibility) mode of the SATA controller.

Don't risk the "registry hack" route if you can avoid it, go for the install process in AHCI native mode and you will get the best results (even in XP, if you have a floppy with the disk drivers to load at the startup) :-P

P.S. If your SATA controller has a "RAID mode", go for it instead (it comprises the AHCI advanced features)....

Well, I have installed the ssd and configured the controler as AHCI. Everything seems functionnal. I will now install nero and check that the nurner is happy with the current setup ( as you say, optical drives should not be affected but some seem to have problems though , due to their firmwares)

Just for the record, for Windows Vista and 7 there is an official "IDE to AHCI" procedure (and fix) released by Microsoft here: http://support.microsoft.com/kb/922976
It is perfectly safe. It is very useful as it will spare you the time lost with a clean install in certain situations.

Why choose RAID if you don't use such a setup?

Tip: If you have intel chipset and AHCI mode enabled in BIOS, it is recommended to install "Intel Rapid Storage Technology".

Because you could is later so if you set it beforehand you won't need to change your configuration....
