Yes you can change that any time.

Most modern motherboards has it enabled by default.

I recommend you go into the BIOS and make sure if it's set to AHCI or IDE before doing anything else.

If it is set to IDE then follow this guide:

AHCI: Enable in Windows 7 / Vista

READ THE ENTIRE GUIDE!!!

DO NOT SKIP ANYTHING!!!

It requires quite a bit more work that just flipping the switch in BIOS. You also need to change a registry entry to enable it in Windows, otherwise you will start getting error messages, you won't get the performance you expect, the lifespan of your SSD will be shorter, etc. If you haven't done anything on the computer yet then it might be best if you reinstall. That way you will be sure than everything such as TRIM is enabled, AHCI mode is properly on, SuperFetch is disabled, and all the other configs Windows automatically does when you install it on an SSD is configured properly.

I did it the other week, one of the posts on there explains it fully. Although I used this video, which walks you through it step by step:

Microsoft also has a fix to enable as well. I do not know the location on The Microsoft website.
