SSD news has flooded in the last couple of days. Head over to AnandTech for Intel's latest, as well as LSI (a fairly new player and new home of SandForce silicon) and OCZ.
Of most interest is the OCZ Vertex 4, built with in-house Indilinx silicon. Prosumer/consumer gear begins to approach enterprise performance; then again, OCZ continues to tout their invasion of the Enterprise Space. One aspect I noticed in the Vertex 4 piece, is that they're reporting random I/O in MBs rather than IOPS. Therefore, one can see that total bytes moved isn't hugely different twixt sequential and random, for the Indilinx silicon. I do wonder how soon it will be that the two components of SSD performance, NAND size and controller sophistication, will collide? At some point, the unreliability of decreasing feature size in the NAND will demand so many cycles in the controller that SSD performance will level out. And, perhaps, decline. Not yet, though.
The Vertex 4 doesn't sound ready for Prime Time Enterprise (no superCap), but for development machines building RDBMS applications using full fledged enterprise SSD, boy howdy is this yummy. (Perversely, OCZ share price is doing a swan dive!) Less and less reason to ignore Dr. Codd.
Despite what the reactionaries assert, the world is not flat nor is it hierarchical. The world is relational. 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. -- 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.

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.
