Choppy/stuttery Playback

Here's my conundrum:

1) I am editing UHD 400 Mb/s ALL-I 24p 10 bit 422 video from a Panasonic GH5.
2) I loaded all of that video on three (3) 10 terrabyte Seagate Barracuda HDDs in a Windows 10 software RAID 0 for a total of 30 terrabytes.
3) I applied no effects or correction and did not layer or stack video tracks on top of each other.
4) During timeline playback the video appeared stuttery after playing for a few moments. When I stopped playback, then started again, the stuttery playback stopped temporarily but soon after resumed, as if the hard drives could not keep up with the video. I also use a Blackmagic Decklink Mini 4K card connected to a 4k monitor. The timeline monitor FPS indicator light remains green and constantly shows 24 fps playback.
5) My hardware exceeds the Davinci Resolve technical requirements.
6) I replaced the HDDs with three (3) Samsung, 4 TB SSDs in a software RAID 0. The playback is still stuttery.
7) Am I to assume I need to set up proxy files? How does that work if I am not applying effects and there are no red lines above my timeline clips? I am confused as how to set up proxy files in order to playback smoother video files rendered at a lower resolution.

Thank you.

I recommend it for all H.264 media. I'm partial to the Cineform 10 bit option at 1/4 resolution.

Read the manual on Optimized Media.

I decided to do that after my post since its better to seek on my own before I pester the forum with incessant questions. Thank you.

Do I need to optimize media for stuttery playback even though the timeline FPS indicator on the playback monitor shows a steady green and steady 23.97 playback?

The question doesn't make sense. At full speed, there won't be a stutter.

You're sure timeline and media frame rates match?

Hugh, try selecting "Show All Video Frames" to see if that helps.

Thank you all for your assistance. Sorry it took so long to get back with you. I moved to a new state and, well, you know how that is!
