In device manager, expand disk drives, right click on your SSD, select the policies tab. This is the way it should be unless you have a battery backup power source in case of power failure. In either case a power failure can cause data corruption, but without enabling write caching you will suffer serious performance loss. I think it is a bigger corruption problem to check the second box.

I leave indexing for my SSD off but have it enabled for my 2 spinners. The SSD can work just as fast without it, unless you have some really fancy timing equipment, you won't notice any difference. It will also lessen the read/write cycles.
I leave Super Fetch turned on as well, it takes little space and helps the system open programs faster than without it, even with a SSD. I gleaned this from my own science experiments and from member whs, our SSD guru.

Do you have Prefetch enabled too?

I think super fetch replaced pre fetch in w7. I don't even have it listed in Services, so I guess I do not.

Prefetch is part of superfetch.

It can be changed in the Registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters

Look for "EnablePrefetcher". 3 is enabled, and 0 is disabled.

Yup, it IS enabled, I don't delve into the registry for Services as a matter of practice though. What would values 1 and 2 do?

Lol, was going to rep all 3 of you, I don't spread it around enough (I know, I spread something pretty good, lol).

To ease your worries, more or less any modern SSD will last decades even if you write 3-4 GB on it per day.

The "limited read-writes before the drive fails" are an issue for servers and companies, as both move hundreds of GB per week like they were peanuts.
