Ubuntu Server RAID Setup & Data Transfer

I need assistance with setting up a Mirror 1 RAID Array on a couple of 1Tb SSD drives and transferring data from my current hotch-potch of drives. All data is equally important and needs to be transferred. The preferred tool for this task is mdadm.

Ideal Skills:
- Extensive experience with Ubuntu Server
- Proficient in RAID configuration, specifically with mdadm
- Strong data transfer skills
- Ability to work with SSD drives

Please note, the project involves both setting up the RAID Array and the data transfer.
