Bought this as a standby when my built-in DVD drives stopped working after upgrading my desktop to Windows 7. They were supposedly compatible but after a fruitless search for W7 drivers to make them work, I bought this to serve as a standby. Now installed, and it does this almost on its own very quickly, I wish I had had this facility from the start in my two year old PC - it's faster, covers DVD formats including DVD RAM that most drives don't, and works like a dream both reading and writing. Despite another reviewer's comments, I have had no problems with noise or speed of this kit - quite the opposite. In short, its better than the originals and I would recommend it highly as a free-standing and transferable drive one could use interchangeably on desktop and laptop(s)though, given its size, it is not meant primarily as a portable drive. At this price and spec this represents a solid, highly functional and reliable drive - just what I wanted!
