Tweaktown published a review of the Lite-On DX-401S Blu-ray USB2.0 ROM Drive.

Quote from the review: "Today we get a look at our second Blu-ray ROM drive to hit our labs, and this time it is from Philips & Lite-On Digital Solutions Corp based out of Taiwan. It actually came to us straight off the factory production line and we are excited to bring you the first review of the product. The first drive we tested was an internal SATA Blu-ray burner as we mentioned just before from ASUS, and while it was cheaper than standalone players, it still had a pretty high asking price. Today we get down and dirty with the Lite-On DX-401S 4X Blu-ray ROM drive which connects to your Windows XP SP2 or Windows Vista based computer via a spare USB 2.0 port. It is essentially a Lite-On DH-4O1S internal SATA Blu-ray ROM placed inside a stylish black and white plastic box with USB 2.0 port and external AC power supply."
