Because loading from RAM is still faster than loading from SSD. tongue.gif

Well, for Windows 7, Intel Toolbox, disabled the Superfetch.

Yeah, so there! biggrin.gif

But seriously, I'd like to understand what the deal is.

Intel says: "In Microsoft Windows 8, Superfetch functions differently than in previous versions of Windows, and should not be disabled for an Intel SSD."

Has anyone uncovered a link as to just how Superfetch functions differently in Win8? Since MS removes "EnableSuperfetch" on SSD systems, it's clearly not doing what it used to do.

Curiously, EnablePrefetcher remains at 3 on SSD systems, which means that ordinary prefetching occurs on Win8 (you can see the results of this in \windows\prefetch).

There must be some reason for it.

What would you prefer, loading stuff at 4kB random read size speeds (down to 30MB/s) or loading at sequential speeds of up to GB/s? Prefetch has the ability to offer the later but it's implementation seems lacking somewhat, at least in W7. W8 brings a newer level of prefetch, but MSDN does not seem to go into much depth about it. frown.gif
