Vmware View Datastore

on the screenshot below, I would like to have an Expert to explain the difference between the datastores on step 6-7-8
I initially thought OS disk and Replica mean the same thing.?
 Persistent I believe is still created off the Master image Snapshot . correct?

Thank you

You have a Master Image or Golden Master which is vSphere Cloned to a Replica and then VMware Composer then creates many Linked Clones.

So

Master Image ---> Replica -----> Linked Clones

The replica is the object which the Linked Clones is created from.

6 - Where the OS of the VDI client is stored. So e.g. the C: drive of the VM

7 - Persistent Disks for VDI VMs are stored. User Data disks! Where users will store there data so the D: drive

8 - Replica Disks are stored - we did replicas in another question, usually these are SSD or Flash Array for SPEED!

So if you are configuring Dedicated VM  then, each data of that VM will be split into different datastores:

- The OS files will be in Datastore1
- The user Data (profile as well the documents saved by user) to Datastore 2
- Replica (it sounds to me like OS files) ? will be in Datastore 3

Correct ?

That is correct, splitting datastores in this way, using tier-ed storage aids performance.
