The data=journal mode protected data, didn't it?

But yes, some people (and Google are apparently enough people to count) want the best possible FS features minus journalling.

Also fsck is probably /faster/ in ext4 than ext2, so Google would be wise to choose ext4 w/o journalling over ext2 even if they did care about fsck performance. Sparse inode structures iirc were a particularly big fsck win.

Apparantly not. I think you want the 'sync' mount option in this case.

Ted's talking about ext4 there, not ext3. Combining delayed allocation with data journalling clearly doesn't make much sense. But point taken.
