Sector by Sector Backup Speed for empty sectors.
My SSD C drive uses approximately 85 GB of the 200 GB partition. If I resize the partition to 100GB, will a Full Sector by Sector image file be smaller and take less time to create? in other words, does AOMEI process empty sectors faster than used sectors in an SxS backup?
If so, I will down size the C drive and leave the space to the right unallocated until need.

There is no real reason to backup all sectors for a normal disk or system backup. Sector by sector will backup up everything on your drive like hibernate files, etc that an intelligent backup won't. You don't need these to restore your system.
Just use first option and don't worry about it.
The difference in size for your backups is a System backup only images the partitions you would need to restore to a running system. A Disk backup will backup all partitions on the drive, ie…a factory recovery partition and any data partitions. Be careful if you do have a data partition, you would want to back that up also. The recovery partition isn't necessary.
