Is native SATA ACHI mode needed for SSDs?

Anonymous

I want to install a SSD in my laptop instead of normal hard drive.

Do I also need to change SATA controller mode to "native ACHI" in the BIOS?

Will these special SSD commands like trim work in "legacy IDE" mode?

Thanks,

    In other technical forum they confirmed that AHCI mode is best for SSD drives. They also advised to use the controller vendor's AHCI driver (such as Intel iastor) if possible, because the Microsoft's msachi has some problems, still unfixed to the date.

    Thank you Sooraj. I've already tried the SSD on my machine with win7 and win8 CP, both look good.

    The last link in your reply (Win7 Q&A) does not mention ACHI mode at all, so I assume that it is not required for the filesystem to do its magic. While the SSD is new, the wear is not sensible.

    Hi,

    You can reinstall Windows 7 on the SSD, but you will have to remove Windows 7 from the old hard drive - you cannot have two installs using the same license.

    Also, read up about the differences of SSD.
