Oh, I misread it ... but still, the modern definition of "excruciatingly slow" doesn't seem all that far off what 90s-era hard drives could do. It is clear from googling though that there's an enormous performance range in SD cards' random write performance, eg wikipedia's entry has a link to http://goughlui.com/2014/01/16/testing-sd-card-performance-round-up/ Seems like it's hard to judge this without knowing exactly which SD card Michael has got in that thing. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
