I tend to agree that the case for SSDs as a revolutionary technology has been significantly overstated. This recent article makes some interesting points: http://www.zdnet.com/article/what-we-learned-about-ssds-in-2015/ I think it's much more true that main memory scaling (in particular, main memory capacity) has had a huge impact, but that trend appears to now be stalling. -- Peter Geoghegan -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
