It's a 'half-way-house' between mounting the drive with 'async' (which is where things like write-behind caching go on - i.e. writing changes to the disk in background) and 'sync' (which is the safe 'default' where all writes are guarenteed to have happened before the system proceeds etc.) 'softupdates' gets you the best of both worlds, almost 'write-behind' like caching (i.e. fast) but if the system dies, you don't trash your filesystems as badly as if they'd been mounted with 'async'.
