No, under Windows 8 SSD’s and RAID’s are ignored by SuperFetch. SuperFetch, under Windows 8 / 8.1 and newer will only run against spinning disk even though the service is running apparently on all disks… it is not working on SSD’s.
You might have wanted to disable the SuperFetch service in the Windows 7 days because of the price of RAM. That is, RAM was more expensive than it is now and so you may not have had all you need. Today, RAM is very cheap so if SuperFetch is using some of it, that is likely a very good thing.
In case you were not aware, SuperFetch is Microsoft’s proprietary service that algorithmically figures out what you are likely to need from your hard drive NEXT (i.e. in the near future BEFORE you click on anything) and loads it into memory thereby making the machine respond much faster.
