Secret's out: Small 15K disk drive market is 'growing'

Re: @Nigel 11

Ever taken apart a 3.5" 15k drive? the platters are tiny, about the same size as the ones in 2.5" drives. Dead space filled in usually with big chunks of aluminium.

LOHAN to suck mighty thruster as it goes off, in a shed

Do it smaller

Given that any rocket will rapidly pressurise any sensible size vacuum chamber unless you have a vacuum pump the size of a shed, you are only really testing ignition at the temperature and pressure required. As such, using the full size monster engine wouldn’t be necessary, the smallest one you can get would test ignition just as well, provided it uses the same fuel composition and ignition method. This would mean a much smaller chamber and pump could be used.

Just make sure you have an adequate pressure release valve that will NOT freeze up ;)
