The small file write performance is far more important than the peak write speed, the time the computer will feel slowest is normally when it has dozens if not hundreds of tiny writes in a queue. Normally its pretty rare to write huge files, even when patching games, encoding media etc, small writes are appended to the end of existing files, which grow over time, its rare that an entire file is re-written except if you are copying a file from one disk to another, or installing a new program. Appending data to the end of the file is more like the 4k random write scenario, than the full on sustained write speed.
End result, the intel drives feel faster in use than just about anything, as they combine a great read speed, with a stunningly good random write speed, with an "acceptable" if not earth shattering sustained write speed.
