It is possible, mkfs with "-O ^has_journal" but then of course you ... 
have no journaling.

However, Intel has always said, I think, that you should treat their 
SSDs just like you would treat any other hard drive, so I probably would 
not hesitate to leave the journal intact.

There is a write lifetime of course, but I think it's much better than 
if you were writing to, say, a securedigital card.
