Question about hdd upgrade, restoring boot disk

[Sleepy81]

I just bought my first Mac, a Mac mini i5 with 4gb ram and the 500gb hdd. (Mac mini 6.1)

I have ordered ram to upgrade it to 16gb, but now I also want to do something with the hdd speed and capacity.

I have a 2,5 inch 750 WD black edition (7200rpm), and want to create a Fusion drive with an SSD. (haven't ordered it yet, but thinking about a 128gb)
Data Diubler kit is already ordered.

However, I have no experience with macs, since I mainly use windows, so I have a question regarding the backup procedure.

Right now, the original disk is in the Mac. Can I do the following:

1. Take out the original 500gb disk.
2. Install the 750gb hdd + the 128gb SSD
3. Create fusion drive using terminal or disk utility.
4. Connect the original 500gb disk to an external hdd enclosure and boot the Mac from this using USB.
5. Restore all the data from the 500gb disk to the fusion drive, creating a bootable fusion drive, using SuperDuper.

I guess what I'm asking is can SuperDuper "clone" all the data from the 500gb disk to the fusion drive, without using superduper to first run a backup of the original disk.

I would swap steps 3 & 4 and create the Fusion drive after booting from the external. Yes, just backup the external 500G to the new fusion drive and you should fine. Make sure you choose bootable backup if given a choice. I use CCC myself.

I also prefer Carbon Copy Cloner.
