You have a second HD in your Optical bay if that's the case.
a 15.2mm thick (the thinnest conventional 2TB hard drive) will not fit into any macbook HD bay out there. Rather 2HD, one in the HD bay, and one in the Opti-bay.
However two 12.5mm thick 1.5TB HD can go into a non-retina Macbook Pro (one in the optical, and one in the HD bay) for a total of 3TB
No SSD or HD inside a computer is storage by definition. Its your computer system data.
1. All data on the computer is just that, your data.
2. All data on the first external HD is your backup.
3. Only the second external HD is your first safe data storage / redundancy.
The single worst mistake almost ALL computer users make is wrongly thinking that an internal HD (or drives) is "data storage". It is not.
"data storage" and "internal" can never be implied of the same HD(s)/SSD or location.
This way of looking at ones data is #1 cause of data loss without exception.
Never consider any computer a data storage device at any time under any circumstance, rather a data creation, sending, and manipulation device. Anyone who thinks data is safe on /in any computer, even copied upon multiple partitions is making a mistake that will, without fail, strike.
You can use the 2nd HD inside the macbook AS a Time Machine backup,... however considering its IN the macbook, if it gets stolen or lost, then the issue and error of logic becomes obvious, and data protection forthwith nullified.
