I've found, inspired by Part 4 just published, this review/test of SSD's and relational databases. Good news. They work.
And in this test, using higher quality retail parts (STEC, EMC, 3Par, etc. aren't used) versus 15K HDD shows how joins are faster, since they test using a TPC-C variant.
Follow, follow, follow, follow the Yellow Brick Road.
Despite what the reactionaries assert, the world is not flat nor is it hierarchical. The world is relational. Infinite granularity yields infinite complexity.

Covid-19 has killed at least 1,123,836 people (as of 20 March 2023, final update)
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. -- Drew Weissman/2022
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.

... 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.

This week's thought
[The intelligence community] argued that [the restrictive amendment] would cripple the program because they typically use it before there is enough evidence to meet a standard of probable cause for a warrant, like early in investigations when they are trying to learn more about a phone number or an email account found to be in contact with a suspected foreign spy or terrorist. -- Charlie Savage/2024 [IOW, let's catch the thief before the horse is out of the barn - the MARF™(party like it's 1829) traitor's worst nightmare]
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.
