the high end enterprise SSDs have supercaps to give them time to flush 
their write buffers to flash in case of power failure events.

but these drives are way more expensive than the $200 120GB stuff you'll 
find in the whitebox market.

the whitebox stuff has fast writes because they buffer them, but in case 
of power failure with pending write operations, all bets are off on your 
data integrity.
