We won't be seeing these charts go to 0 in a few short years. Hard drives are at 2.7¢/GB while SSDs are at 21.9¢/GB, and that gap won't be closed with just one or two generations of NAND even if hard drives don't get any cheaper. We will increasingly see parts of the hard drive market killed off by SSDs, as the market for low-capacity 2.5" drives has been. Hard drives are shifting from being mainstream storage to archive storage, with things like shingled magnetic recording making hard drives inherently more tape-like. That's why Western Digital had to make a big SSD acquisition (SanDisk), and why Seagate needs to grow their SSD offerings by a lot.
