    Any virtual memory system that has to make use of page files, swap files, or swap partitions because the application(s) require more memory than the computer has in RAM are potentially going to slow down the memory access.

    With multiple applications running concurrently, this might not actually be a problem as the system can switch to a different application while it swaps memory pages to and from disk for an application that needs more memory space or has some pages swapped out to disk.

    The amount of degradation will depend on the speed of the disk drives concerned and the speed of the interface that the disk drive(s) are using.

    SSDs are probably best avoided as the potential for doing large numbers of writes exists and this can reduce the life of an SSD.

    Tertiary storage (on tape or similar media) can really slow things down, and is rarely used nowadays.

    I hope this helps.

    secondary storage is larger but it is slow to the primary memory

    Yeah big data chunks from like SSD or (gasp) disk are slower than system DRAM memory.

    No they do not slow memory access.
