Data storage is one example, a lot of time loading of data from HDD was the n°1 performance issue as it was thousands of time slower than CPUs ; nowadays the fastest SSDs have sequential reads that read at 12GB/s (DDR3-1600 speeds!) which can easily be much faster that whatever non-trivial processing you'll apply to the data, so the bottleneck moved from IO to CPU.
