The amount of TB's is important of course because the system must be able to provide the storage amount but its also about performance. We use IBM V5030E systems and under maximum load with 48 nearline drives these systems are at about 30% load so they are overkill for 48 drive systems, the nearline drivers aren't fast enough to max out the cpus on the storage controllers. But we also have a customer running a Netapp storage solution, not an Ontap system but a simple entry-level SAN solution with high density storage that has >100 nearline drivers in it. That solution does in fact get very close to being CPU bound under maximum Spectrum Protect load. So I would stick with the amount of nearline drives the blueprint suggest for the performance you see in the blueprints and ask the storage provider what storage controller you need to be sure that the drivers don't overwhelm the controllers, take some growth into account etc. You can compare random read I/O (check the block sizes) between manufacturers to see how they compare, it's never a 100% accurate but it will give you a better indication than sequential imho. With most high end storage systems using nearline drivers you will basically always have the drivers as a bottleneck because a 7.2K drive just doesn't really perform that well and most high-end storage solutions are build for flash and can do insane amounts of IOP/s given the correct storage.
I think Spectrum Protect has become very I/O efficient since they introduced the containerpool, especially when comparing it to the old filepool using dedup.
