Solid-State Drives (SSD)

[CptDobey]

Hello,

I own a Crucial SSD M225 64 GB and I have some questions about it. I browsed through the forums but I did not find definitive answers to them.

I am using Windows 7 Family Premium 64 bits. I installed the latest bios on the M225, the 1819, before installing W7. I formated the SSD during W7 installation.

In order to maximize the drive speed, do I have to enable the AHCI controller or can I just use "IDE" controller?

If I use "IDE", will the trim function be enabled automatically?

As Windows 7 seems to be "SSD aware", do I have to deactivate anything like files indexation or automatic defrag as it is suggested into some tutorials about SSD with XP or Vista?

Is there any way to be sure W7 is seeing my M225 as a SSD and not as a usual hard drive (and thus activating trim)?

Thanks in advance for your answers.

Regards,
Philippe

You can use IDE or AHCI as long as you use the drivers that come with Windows and don't install any 3rd party AHCI drivers.  There shouldn't be any real world difference between the 2 on an SSD though I suppose any mechanical drives still in your PC might benefit form the NCQ support in AHCI.

Trim is active in Windows 7 for all drives by default - it's simply ignored by most, so technically it doesn't matter whether it thinks it's a hard disk or not.  The only difference is whether it disables certain services or not.  You can check the appropriate services by following these instructions: http://www.forum.crucial.com/t5/Solid-State-Drives-SSD/SSD-Tweaks-for-vista/m-p/4913#M748
