    I have a Lenovo X200 and I'm thinking about buying a SSD soon. I'm thinking of getting the Intel 80GB SSD (Gen. 2). However, I'm not sure if the X200 have AHCI support. I read that the BIOS needs to support it in order for Windows 7 to utilize TRIM. Is this true? If not, how do I enable AHCI in the BIOS to activate TRIM? Yes, I have Windows 7 Professional installed on my machine, but it's on an HDD at the moment.

    How do you know it works? Did you changed anything in the BIOS?

    See this:

    How do I know if TRIM is working in Windows 7?

    Go to the Command Prompt and type:

    fsutil behavior query disabledeletenotify

    DisableDeleteNotify = 1 (Windows TRIM commands are disabled)
    DisableDeleteNotify = 0 (Windows TRIM commands are enabled)

    This begs the question, how would you know it's not working? And really how important is it to you if you can't even tell if it is working.

    @King Arth, did you flip those?

    I see, I guess windows 7 has trim commands running regardless of whether or not your SSD supports it. It's enabled on my Intel G1, which crystaldiskinfo confirms does not have TRIM

    Well I would guess that windows 7 detects it's an SSD, so enables TRIM, but it's really not running since the G1 doesn't support it, it's just that on the OS side of things windows is reporting that it's enabled.

    Doesn't the BIOS have to support AHCI in order for Windows 7 to TRIM the SSD?

    I don't, but that's why I'm asking so hopefully it'll lead to the truth somewhere down the line.

    The G1 absolutely does not support TRIM, and Intel has said they wont release a firmware update for it that does. So you cannot have it with the G1. As I said windows 7 supports it, so on it's side probably has it enabled, and would report that, but on the hardware side of things, it simply will not work. So in this case, the right hand really doesn't know what the left hand is doing.

    After 6 months without TRIM, I have had four with it. I have not noticed any difference.
