I visit the PostgreSQL site pretty often, and yesterday there was a link to a post on Bruce Momjian's blog (he's a Big Wig in the PostgreSQL world) about SSD. I was moved to comment, and then today saw that AnandTech has just published a review of a new SSD. Herewith my next comment, as it's relevant to this endeavor and I'll assume that y'all don't visit Bruce as a matter of course.
Just for grins, and because it's timely (published today), here's the latest AnandTech SSD review: http://www.anandtech.com/show/3656/corsairs-force-ssd-reviewed-sf1200-is-very-good .
What's important about this review:
- it's for a SandForce 1200 controller, which is intended to be SF's vanilla retail controller
- it's really fast
- it uses no external DRAM cache, which is material to design decisions about how to build an SSD, which makes SF based SSD materially different from all others, retail or "enterprise"
- one can see the playing field of most retail SSD and top notch retail HDD in the tables
SSD are not yet commodity parts, unlike HDD. Evolution continues; hopefully so will decisions about how best to utilize them in RDBMS.
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.

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.
