Hello fellow cMP pilots.
Thanks to all who contribute to the forum.
It’s really helpful and appreciated.
My primary objective is to make my Mid 2010 5,1 edit Final Cut Pro X 4K footage effortlessly, if that’s possible?
Final Cut Pro X (FCPX) frustration examples:
- adding a transition and wanting to view/play it immediately without stutter, and without waiting several seconds for it to render.
- scrubbing is not smooth on a 4K timeline.
- can’t play-back 4K on the timeline without dropped frames / without creating proxies.
Random FCPX notes:
I always transcode to ProRes on import.
I almost always export to H.264.
Most of my footage comes from the Sony A7III and Phantom 4 Pro.
I recently upgraded both CPU’s and GPU; noticed almost no real-world improvement when editing.
I recently learned the old-tech SATA 2 bus in the cMP is a known I/O bottleneck?
Am I on the right track thinking I/O is the culprit?
My boot drive is a 500GB Crucial SSD.
My remaining drives are all HD’s… listed at bottom of page.
FCPX lives on the SSD.
My FCPX Libraries live on one of the 6TB WDC 7200 HD’s.
Attached are two disk speed test results, in case they're helpful.
I’ve been doing a bunch of reading about I/O here, among other places:

These two NVMe PCIe Adaptors seem to have a good reputation:

If you feel a PCIe Adaptor is the way I need to go, which NVMe drive blades have worked well in your experience, in terms of making a real difference speeding-up FCPX?
How might a backed-up RAID-0 factor into this whole thing, considering the drives I have on hand?
This is all a bit of a head-scratcher??
I don’t know what I don’t know.
Thanks very much in advance!
