I am currently doing my first backup since installing a new SSD to replace my aging HDD. It is taking a much longer time to do this backup than previous. Is this because the harddrive is new and its the first one since installing. Everything else works much faster and the spinning wheel gone. Total backup data is 78.29GB.

A fews things - very loosely speaking - that will affect your backup time:
1. If the backups on your old HDD were incremental, they would be small. If this is your first backup and your backup destination doesn't see the SSD as being the same backup source as the HDD, it may be doing a first-time backup of the entire drive contents, which would take much more time.

2. What kind of disk(s) is/are your backup drive (SSD, HDD, RAID)? You could have the fastest source drive in the world, but if your backup drive is slower, that's the bottleneck.

3. What kind of connection (USB 2.0, 3.0, ethernet, wifi, thunderbolt) are you using to your backup drive? You can have the fastest source and backup drives in the world, but if your connection is slower, that's the bottleneck.

3. Are you backing up many small files, or fewer large files? Byte for byte, there's a lot more overhead in transferring smaller files than a few large files. This can also affect your backup time.

4. Are you using Time Machine? I love Time Machine but it'll never go very fast, especially on first-time backups, because it wants to prioritize your system's resources for the user, not background backups.

Hope this helps narrow it down.

For only 80gb, I'd suggest you try either CarbonCopyCloner or SuperDuper (instead of TM, if that's what you're using).

Both are FREE to download and try for 30 days.
Both will create BOOTABLE cloned backups.
Can save you LOTS of downtime and headaches in a "moment of extreme need"...
