I had bought this Blu-Ray drive, because I just wanted to have a player for Blu-Rays. I found it very convenient. The data transfer rate is pretty good, Windows 7 has the drive also well recognized. Unfortunately, the drive is very often crashed in the middle of reading operations. Since mostly only helped drive new zustarten (cable out, wait, cable reconnect). Sometimes it did not work then and there, and you had to wait a little. For me, the drive is not usable, so I sent it back and then it brought me a burner from Panasonic, even though I do not really need the burning function.
