Capacities
The seventh-generation iPad is still only available in 32 GB and 128 GB versions — the same capacities offered in the sixth-gen model. The iPad Air comes in 64 GB and 256 GB versions, which may also help to justify the price difference if you’re looking for more capacity, although it’s worth noting that the 128 GB iPad is still $70 cheaper than the 64 GB iPad Air.
The iPad Pro has the same 64 GB and 256 GB versions as the iPad Air, but also offers 512 GB and 1 TB models for those who need significantly more space.
