    I have 4 Intel 320 series ssd's in a RAID 0 array on an areca 1882 raid controller with 4GB of cache. Would having a ram disk or program like fancy cache have any real world benefit for me or would it be purely synthetic placebo effect type of thing?

    I only ask this because I still get stuttering on my system when doing tasks that involve the disk systems. I was wondering if using that would alleviate that issue or not really.

    Thank you for any help.

    A RAM disk isn't going to help you.

    Have you tried the disks not raided?

    You can open resource monitor during the activities you are talking about, and notice which is reaching 100% usage, is it the cpu or the disk, there you will know which is causing the slow downs.

    Hint: it is the cpu.

    I ended up replacing those drives with Samsung 830 series drives and the stuttering has seemed to subside quite a bit. It is still there every now and then but a lot less severe.

    CPU is never maxing out when these slow downs happen.

    If your computer have 4 threads then a cpu usage of 25% percentage is enough to cause some slow downs.

    That is why you should monitor "disk utilization" and not "cpu usage".

    Real world benefit depends on real world usage scenarios. RAM disk will still be faster than the raid setup. Much faster.
