Was i correct in understanding that if you use an SSD drive, Windows 7 will automatically shut off specific windows services such as defrag, superfetch...etc.?

Cause i got an Corsair Real ssd, the fastest in the world supposedly, install W7 and later realized Superfetch, defrag is running. I know i can manually shut them down, i just wanted to know why W7 did not do so itself? would this mean an error in W7 detecting my drive properly affecting Trim and garbage?

this quoted from msn blog

Windows 7 will disable disk defragmentation on SSD system drives. Because SSDs perform extremely well on random read operations, defragmenting files isn’t helpful enough to warrant the added disk writing defragmentation produces. The FAQ section below has some additional details.
Be default, Windows 7 will disable Superfetch, ReadyBoost, as well as boot and application launch prefetching on SSDs with good random read, random write and flush performance. These technologies were all designed to improve performance on traditional HDDs, where random read performance could easily be a major bottleneck. See the FAQ section for more details.
Since SSDs tend to perform at their best when the operating system’s partitions are created with the SSD’s alignment needs in mind, all of the partition-creating tools in Windows 7 place newly created partitions with the appropriate alignment.

I still can't any specific info about TRIM and Garbage collection, would they still function ok?
Hard to believe W7 been around this long and still have troubles detecting a simple SSD properly, bet it never gets fixed either.

It's important to shut off those services one way or another if the OS doesn't do it for you. SSD's have a relatively short life compared to mechanical drives and each memory location has a limited number of writes before it fails. Anything that increases that rate, such as defragging, reduces the overall lifespan of the drive.
