When installing Windows 7 on a new SSD unit with just a single partition, should I care about:

  • partition alignment?
  • enabling SSD optimizations?
  • disabling HDD stuff (defrag, superfetch, etc)?

Or will it detect and configure all automatically?

Nice article on Lifehacker, explains everything, see section "Popular Tweaks That You Probably Don't Need"

You also may want to apply this Windows patch after windows is installed, not sure if automatic Windows Updates applies this one or not.

Long answer: Yes ... Windows 7 will auto configure SSD drives.

Yes he should care, or yes it will configure all automatically? – Ben Voigt May 5 '12 at 0:19
@BenVoigt Yes, Windows 7 will auto configure SSD drives. – pcunite Jun 7 '12 at 22:53
So please put that into your answer, to make it clear. The OP did after all ask more than one question. – Ben Voigt Jun 8 '12 at 2:27

This is not a reliable answer since it is not based on formal research, but on my own experience.

I installed a brand new unformatted SSD after enabling AHCI in the BIOS, and removed the existing HDD. Put Windows 7 disc in the DVD drive and...

What W7 did:

  • It properly created a new NTFS partition and also created a hidden system partition to ensure correct alignment.
  • It enabled TRIM.

What W7 forgot about:

  • It did not disable superfetch.
  • It did not disable prefetcher.
  • It did not disable defrag.

I also disabled indexing.
