Need to transfer my info from Time Machine to recently purchased MBPro

I just recently purchased a used MBP Early 2011 with an SSD drive in it. Heres the info for that:

• Physical Volumes:
  • disk0s2:
  • Device Name: Samsung SSD 840 EVO 250GB
  • Media Name: Samsung SSD 840 EVO 250GB Media
  • Size: 249.2 GB (249,199,591,424 bytes)
  • Medium Type: SSD
  • Protocol: SATA
  • Internal: Yes
  • Partition Map Type: GPT (GUID Partition Table)
  • Status: Online
  • S.M.A.R.T. Status: Verified
  • PV UUID: 2F86FB24-0DE2-4DAE-AEDE-DC201298F766

Now, my problem is that I don't have enough space on this to restore from Time machine backup, so, I'm being told I can add a second hard drive in the space where my optical drive is. Here is that info:

• HL-DT-ST DVDRW GS31N:
  • Firmware Revision: TA17
  • Interconnect: ATAPI
  • Burn Support: Yes (Apple Shipping Drive)
  • Cache: 2048 KB
  • Reads DVD: Yes
  • CD-Write: -R, -RW
  • DVD-Write: -R, -R DL, -RW, +R, +R DL, +RW
  • Write Strategies: CD-TAO, CD-SAO, CD-Raw, DVD-DAO
  • Media: To show the available burn speeds, insert a disc and choose File > Refresh Information

So thats where I'm at currently and I'd like to know what kind of hardware I need to add the 2nd hard drive. I would like it to be at least 1 TB drive so I can backup from TM and move forward.

Thanks in advance
