Too many horror stories with pDrive about people getting locked out and never seeing their data again, and their terms lay it out that they own what you upload not you. That scared me away from pDrive.

I moved to kDrive and it has done everything I need so far. It's a little slow to transfer if you are in the US since their servers are in the EU, but that's a minor complaint and only a hurdle I had to worry about once during initial sync... It's hardly noticeable with everyday changed to individual files.

The Google drive integrations in dolphin / KDE work well enough but it doesn't have an option to "sync" folders in a local drive like the windows client did, and that was my main use case. Same with dropbox, you get one sync folder on your main OS drive. I have 8 storage drives in my computer and I have more data that needs synced and backed up than will fit on my main OS drive.
