Yeah... personally, that is someone smoking the "paranoia" crack. I've
only ever had problems when I was using a couple of western digital
drives and then it was corrected by firmware updates to the drives.
(replacement from Western Digital)
Show me where this has really been a problem in the last 4 years. Before
then, maybe. Things have changed firmware has gotten better, write
caching is still okay to use. Why else would manufacturers put cache
ON-BOARD the hard-drives if it was BAD... do you think they LIKE
SPENDING MONEY on things that won't be used? They would rather just not
include it and save more money.
