I'd say it's the other way round: write cache is dangerous with
softupdates. Softupdates itself is certainly better than no
softupdates, even if it takes a slight performance drop by disabling
write cache.

I think you should disable the write cache on the 3ware cache (not
sure whether there actually is one, mine don't come with any RAM
sockets) anyway as you'll lose all data in there in the event of a
crash.
