By a nurse with an SSD for a brain. You'll get through that meal quick.

My understanding is as Geneo posted, earlier: Windows 7 monitors your boot drive, and only automatically disables SuperFetch (and Prefetcher???) if it decides your SSD is fast enough. That must mean that some are too slow.

As a reference: I am using generation 2 Intel SSD's (with the latest firmware) and if I disable Superfetch, my OS & apps boot times slow down dramatically. I'm about to switch to an OCZ RevoDrive, so it will be interesting to see what happens.

Anyway, I really don't see any great need to disable these manually, what's the big deal? A 4 year lifespan instead of 5 years?

-but I also admit to being kind of confused on this. (g)

I have the same on my Intel 320. Superfetch on is faster with some software. So I left mine on.
On a 120GB as this one is there is plenty of space for it so why not.

It seems on the newer drives you try it both ways for your SSD and set up and which ever works best that is the way to go.

My 2 cents.

Although it may have been answered here, I didn't see it: how does Windows 7 react to a system that has a spinning data drive in addition to an SSD system disk? If it determines that the SSD is fast enough to disable the various features mentioned above, are they still enabled for the mechanical drive? Or does it not disable anything if it sees a mechanical drive regardless of SSD?

I do not understand this discussion regarding Superfetch. Why would anybody want to disable that. RAM is still a lot faster than any SSD and a nice pack of cached stuff enhances performance.

Am I missing something. Please enlighten me.

PS: The argument of extra write operations to the SSD does not count. That is a phony argument. SSDs do not wear out as long as you care to keep it.

Please start a new thread. Then state a question concerning your inquiry.

There are nine pages in this thread so I have no remembrance of all that was covered.

Thank you.

OK, though I thought here was appropriate because the thread had recent posts and my question is exactly aligned with the content of the thread.
