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

Seems like it's hard to judge this without knowing exactly which
SD card Michael has got in that thing.
