If you were todo something like that, you'd be using the flash memory as a boot disk and everything would be getting loaded into RAM - so the flash disk would not be getting accessed afterwords at all.
Of course this would be easier done with linux the
Windows....but if you disabled the swap file (do-able if you've enough RAM) and pointed the internet cache towards a RAM drive maybe you could do it with 'doze and not batter the flash RAM.
But either way you would not need an 8gb card.
