42c per gig is VERY expensive, more than 10 times the price of 15k SAS at volume. SSDs - while I didn't say "are not used" in enterprise - are "generally" not used. As in, for every $10mill enterprise spends on SAS drives, they spend maybe a few hundred thou on SSD.
The market for SSDs is elsewhere.
googles to check. YUP http://www.anandtech.com/show/10348/q1-2016-market-trends-ss... http://www.anandtech.com/show/10098/market-views-2015-hard-d... WD alone ships 3 times more enterprise HDD than the entire enterprise SSD market. roughly speaking Enterprise HDD is about the same size as the entire SSD market.
My pissy comes from HN becoming more and more "pimp my company/product" and downvote to hell anyone remotely critical, with less "news about hacking".
