Re: Primocache Prefetching from HDD and not SSD?

Thank you for the confirmation. I'd certainly be setting prefetch from L2 if that were an option.

Re: Primocache Prefetching from HDD and not SSD?

You're assuming that the L2 has a 100% copy of what was in the L1. To my knowledge they are allowed to keep different blocks in each, which would mean a L1 prefetch doesn't necessarily have to come from the L2. Yes, my assumption is that the L1 is the mostly accessed blocks of L2, which is the most...

Otherwise I'd expect the SSD to show 100% instead on windows task manager. The HDD when prefetching runs between 80 an...
