E7450 SSD partition question/issue

I recently upgrade my OEM mSATA 256GB SSD to a WD Blue 1 TB 3D NAND SATA drive formated to NTFS and cloned the OEM HD to my new one. Prior to swapping the HD I ensured by Bios, all Dell system files and drivers were updated.

The new drive partitions don't look right showing FIVE different partitions. I ran into a very unexpected "low memory" warning of some kind which is what lead me to check Disc Management. (There were several months between researching compatible drives and installing this one but I think I kind of recall reading .that only 500GB would be usable due to E7450 MB limitations. I tried searching for max SSD HD memory access after install and could not seem to find a related link)

Only one HD installed but Disc Management showing a Disc 0 (with the five paritions) and a Disk 1 (with 9351.5 GB unallocated) which I initially thought was on account of the MB having a limit of 500GB access if I remembered that part right but the numbers still don't seem to add up correctly compard to Disc 0)

Disc 0 Partitions:

-System 167 MB 

-Unallocated 181 MB

-Windows (C:) 237.65 GB

-Recovery Partition 495 MB

-Unallocated 692.55 GB

-Recovery Partiton 500 MB

I did run a disc clean up and trim task just to see if it made any difference but nothing significant. Something seems not quite right here and I am not quite sure what the right questions are to ask.

Q1 Why are there five partitions with duplicate recovery partitions? 

Q2 Did I remember correctly that there was a limit of 500GB?

Q3 Is it possible to merge the 692.55 GB partition to the Windows C partition without reformatting and starting over?

Thanks in advance
