Concerning the workflows:They are separate. The two hardware chains are independent and not synced.
I put the processed jpegs on the cloud. The RAW files are stored on the RAID unit.
So far I did not care to save the CNX-D processing parameters anywhere. Most of my pics are snapshots, distributed to relatives or friends, often via social networks, so why care. I reckon that, if I were to have another edition of any picture, I'd redo the processing anyway, e.g. with the latest de-noising filter, color profile and sharpening matching the targeted media (print or screen) etc.
Anyway, my post-processing is generally light-handed. I try to get the picture right "on the spot", rather than using it at raw material. Most frequently, PP means slight cropping (change of proportions, esp. for vertical frames), white balance adjustment, and B&W conversion every now and then.
If I were to perform heavy processing, that would be with LR or Photoshop, not CNX-D. In such case, the parameters are stored on the RAID too, and the catalogue also gets backed up.
Concerning CNX-D performance:
it is very fast (display and correction) to medium fast (processing of output jpegs) on my laptop, which is a M$ Surface 4 with an SSD.
Windows & windows apps generally show a tendency to slowing down that looks like wilful, programmed obsolesence, even on computers with no connections and no config changes (example: the PC that I had been using for ten years for my virtual organ). However, with the help of the SSD, such ailments do not seem to appear. Microsoft will sure fix that in the near future

Sometimes there are cures. For instance, concerning the non-responsiveness of Windows: processor activity would show spikes resulting in loud & ugly cracking sounds from my virtual organ. Culprit is the SysMain service, the new name of an old service that is supposed to "improve user experience" by pre-loading the most frequently used apps, even when the user has absolutely no intention to put them at work. This service has been there for more than a decade. I'm not really surprized M$ was not able to make it behave properly. Killing it is, fortunately, no problem, as the Windows system won't retaliate. There are other unsolicited background activities that I'd like to silence. On the other hand, Onedrive sync used to work like a breeze on Windows 8, but its user interface got crippled on Win 8.1, and now synchronization no longer works properly on Win 10: it can be delayed for weeks with for apparent reason, and cannot even be forced. Delenda Microsoft.
