The comparison is a bit self-serving
The SSD market is, despite the best efforts of drive makers, NOT slavishly following the "enterprise" classification beloved of HDD makers. Enterprises are moving to appliance level redundancy and that implies cheaper SSDs are good enough.The figures from Gartner don't include this large SSD segment and so understate the impact of SSD on "enterprise" HDD sales by a considerable factor.
What is surprising is that there are still good sales levels for those very expensive "enterprise" drives. Prices are 2 to 3x those of comparably sized mid-range SSD, which makes any rationale for staying with these HDD unfathomable!
