Couldn't find any tread on Asus K401UB ultrabook. I bought one today from Asus dealer, upgraded the ram & also to check on the mb. To my surprise & lengthy discussion with the retailer, our local model of K401UB does not come with 24GB ssd. Unlike the same model that is sold in Taiwan & Singapore which comes with the 24GB ssd in addition to 1TB hdd, the Malaysian model is void of the ssd. The empty half size msata ssd is there for us to insert.

So buyers beware of the missing ssd. There will be a big difference in performance without the 24GB ssd cache.

Plan to get 128GB half size msata ssd to test on this machine. If possible I prefer the Win OS to be on the ssd & leave the 1TB hdd for data files.
