I actually was using a 3TBx2 configuration (RAID 1) on Proxmox which was hosting a Windows Server 2012 R2 system. I then tested various caching configurations for speed changes ranging from no cache all the way to writeback, but there was no major differences to the encrypted write speeds (though that VM did have 6 core's at it's disposal and was never more than 50% usage), though there was to the normal copy-paste write speeds.
On the home sever that was having the slightly better encryption speeds, it was a basic 750GB 7200RPM drive for the OS with the cloud drives caching onto the 3TBx2 Storage Spaces drive I had setup for the media. I was not really able to configure it too much, but I did try various configurations including caching on the single drive vs the Storage Spaces drive, and it was generally about the same.
I've come to the realization that this technology is amazing, in theory, and when push comes to shove it's just not quite ready for the prime-time for large-content storage of data for a Plex setup (though for long-term/infrequent access it's amazing), whether it's using Google Drive or Amazon Cloud Drive.
I'll be keeping an eye on this for developments, but in the meantime I downgraded my main server since I didn't need so much HDD space/CPU cores to handle the encrypting/decrypting and just upgraded my Internet and local hardware to host it locally!
Best of luck with this endeavor and I hope this matures enough after public release for me to be able to begin using it in a production-style environment!
