Could the SSD revolution already be over? Last week, Western Digital (actually the Hitachi folks they recently bought) announced the imminent release of helium filled hard drives. This story doesn't mention size, price, or availability. The only numbers: rather than five platters, these drives will have seven. That's a 40% increase, and for less power.
Dum da dum dum. Short stroking a hoard of these might be just as cost effective as equivalent SSD. Don't know yet. But could be. Does it matter? In a sense no, in that the point of SSD, so far as I've been concerned, is that SSD was an obvious finger pointing to high normal form databases as the solution to both byte bloat and application performance. For single disk machines, RAID/10 isn't an option, of course, but the point has been database servers, where a RAID set versus SSD is a feasible trade off.
IFF AI, as currently implemented, can intuit Special Relativity from just a clock tower and a moving tram will I take AI seriously.
Infinite granularity yields infinite complexity.

Scientists aren't vocal enough about science. There are large groups of people who think scientists are all frauds and who don't
believe in science, and they're being cultured by some of our far right-wing politicians, religious leaders and community leaders. -- Dr. McElhone/1974

To date, Microsoft is stating that organizations testing In-Memory OLTP have
seen transaction speeds improve by up to 30 times compared to past
performance, with the best performance gains achieved when the business
logic resides in the database and not in the applications.

I have had to explain and re-explain and re-explain and re-explain, you know, how relational databases work, what is an eigenvector,
what is dimensionality reduction.
-- Christopher Wylie/2018
... but Flash-based storage has such a different performance profile from rotating media, that I suspect that it will end up having
a large impact on filesystem design. Right now, most filesystems tend to be designed with the latencies of rotating media in mind.

Election day's thought
Democracy is the theory that the common people know what they want, and deserve to get it good and hard. -- H. L. Menken/1915 [
See you next week in a brand new show©Heckle and Jeckle
In a time of SSD, multi-core/processor, two terabyte memory and Optane App Direct Mode machines, there is no reason not to
build from BCNF data. Time to do what Dr. Codd demonstrated. Technology has finally caught up with the maths.

Shameless Plug
I know a little something about SQL, DB2 (preferably LUW, z/OS if the money's right), Oracle, SQL Server, Postgres, and database design in general. Mentoring/teaching/consulting on a short term basis, too. And a bit of stat analysis if it's R.
