The physical specs of the 2TB hard drive seem compatible: 2TB 5400 RPM 32MB Cache SATA 6.0Gb/s 2.5" 9.5mm high. Is there any incompatibility other than physical that would prevent from upgrading with that hard drive?
Thanks. Fred.

Any 2.5" SATA drive should work fine. One standard trick to get a speed bump is to replace the current internal hard drive with:
You can then take your larger traditional hard drive and swap it into the optical drive bay with an appropriate mounting bracket. This gives you the speed advantage of the faster boot drive, with the storage space of a traditional hard drive.

I would go with a SSHD (hybrid HD). The newer MacBook Pros have SATA speed issues with a dual drive setup and the head crash protection does not work if you move the HD over to the optical drive location.
One other option I've been hoping for is the WD Black2 which is a dual drive within a single device. So far they have not offered it for the Mac's yet.
Does Western Digital specifically state that the Black2 is incompatible with Macs? I've been assuming that the mechanism is similar to the Fusion Drive that Apple's installing in iMacs and minis. If the Black2 appears in the Finder/Disk Utility as two separate drives, shouldn't it be possible to smush them together as a Fusion drive, using Terminal?
So far its not compatible as the physical SATA port needs to be split across the two drives which needs a splitter driver within the OS. I keep hoping ;-}
Just an update to this discussion, in case anyone comes back to this: WDC now supports the Black2 SSHD with OS X, under both 10.9/Mavericks and 10.10/Yosemite. Utilities are available at the link for configuration as a Fusion Drive or as separate SSD+HD volumes.

As far as I know, you shouldnt get problems as long as your SSD/HDD has a capacity of less than 2.19 TB !
I suggest reading http://www.wdc.com/wdproducts/library/Wh... yourself ...
... limitations of 512-byte Sector Size may prefent you from using drives with higher capacity and there might be problems with capacities of more than 4TB, HFS+ should support volume sizes of up to 80000000 TB = 8 exabyte ( https://en.wikipedia.org/wiki/HFS_Plus )

No, the drives limit is not its storage size but its physical size as it can't be higher than 9.5 mm for the MacBook Pro's limited space. OS-X has a newer version of format which removes all limits in the storage size. In fact Apple sells iMac systems today that have 3 TB drives.
That doesnt mean that no problems would arise for drives with more than 4 or 8 TB !
The problem could be hidden in the hardware of the SATA interface, which sureley will not be able to adress drives with up to 8 exabytes !
The questions is how many BIT does the SATA interface hardware have for adressing sectors of a drive ...
We have a couple of very large RAID storage systems one which is 16 TB! So not to worry ;-} The OS file system can support it.
RAID storage systems are usually not connected to a MacBookPro by its INTERNAL SATA interface !
You're mixing things! SATA & the OS file system have very different limits!
SATA is limited by its 48-bit LBA addressing which pushes the upper drive limit to well over a Petabyte per the single SATA connection. The OS's limit is even higher! 8 Exabyte as you have noted.
The SATA port issue would be an issue with either the MacBook Pro or a RAID rack system if there was one (which we know there isn't).
