Yes, you can replace the HD with the same 1TB HD from WD or use a newer cheaper model from WD or Seagate. The very newest versions of these drives implement Apples thermo spec of SMART (Apple does not use an external sensor on the newer models). Even if you get a non-conforming HD you still can get it to work with the addition of a third party system add-on Fan Control that works with other thermo sensor SMART spec'ed HD's and non-SMART disks as well. I would recommend getting Temperature Gauge app from the App Store to monitor your sensors and fans as well.

I would recommend getting the 2nd HD/SSD mounting kit from iFixIt for your system to mount your SSD to using the second HD/SSD SATA interface your system has so you don't need to swap out the optical drive. Make sure the SSD you buy is rated for your system some don't have a means to be set for the correct SATA I/O speed.

As there data sheet states it does then it must. If you are worried here give them a call or email to double check if they have any open issues with the units.
