The reason I am looking for larger cards is shooting HDR photos!....Julian
At 5MB per JPEG, a 32GB memory card ideally could contain *5,468 photos. But formatting takes about 10% of that space, so let's call it 4921 photos. RAW images are bigger and fewer could be held. But your camera doesn't shoot RAW, so we can ignore it. You can re-adjust these numbers if your files sizes are different.
If shooting a 3 image HDR stack, you can hold 1640 HDR stacks on a 32GB card.
If shooting a 5 image HDR stack, you can hold 984 HDR stacks on a 32GB card.
Now, let's consider that that 1TB card. It is exactly 32 times larger than the 32GB card. So, let's recompute
If shooting a 3 image HDR stack, you can hold 52480 HDR stacks on a 1TB card.
If shooting a 5 image HDR stack, you can hold 31488 HDR stacks on a 1TB card.
Now let's suppose you are really, really efficient and can find a subject to shoot an HDR stack once every minute. So, let's compute how many days of shooting you would have to do shooting 12 hours a day with an HDR stack once every minute. (Eventually the sun will set, and you will have to stop until the sun rises again and besides, you will need to re-charge a gaggle of batteries)
Using a 3 image HDR stack, you would have to shoot for 73 days.
Using a 5 image HDR stack, you would have to shoot for 44 days.
This is how big that card is!!!
And now comes the processing of all of those HDR stacks. Guess we won't hearing from you again for quite a while!

Just thought of something. You might be having the camera produce the final HDR image. Then the 3 image HDR stack becomes 4 images with the resultant HDR output. And the 5 image HDR stack becomes 6 images with the resultant HDR output.
If shooting a 3 image HDR stack plus an HDR result, you can now hold 1367 HDR stacks + result on a 32GB card.
If shooting a 5 image HDR stack plus an HDR result, you can now hold 911 HDR stacks + result on a 32GB card.
If shooting a 3 image HDR stack plus an HDR result, you can now hold 43744 HDR stacks + result on a 1TB card.
If shooting a 5 image HDR stack plus an HDR result, you can now hold 29152 HDR stacks + result on a 1TB card.
Using a 3 image HDR stack + result, you would have to shoot for 61 days.
Using a 5 image HDR stack + result, you would have to shoot for 41 days.
At least now you have an end date in sight to complete the filling of the card!
