An as yet unidentified problem with one or more of motherboard, cpu or
memory.  I suspect the motherboard. I originally suspected the PSU,
but a fully tested replacement was no help.

Yeah, I'm seriously considering that option, but 2k is well out of my
league at present ... the recession (soon to get worse) has already
badly hit my income.

 I now know a lot more than I ever wanted to about Linux RAID, but
it'll probably be out of my head by the time another emergency occurs.

Thanks for the tip on write performance.
