I wanted to insulate my Blu-Ray burner 5 "1/4 (SATA) to use it on multiple computers. After an unfortunate experience with the same article but repackaged by Amazon and not working (disks detected by the OS but impossible to read), I just received a new and everything works perfectly. I can play Blu Ray on all my ordis. Ultimately, I will be fine me the monumental side (style "audiophile" with a net over-size compared to the reader located inside + blue light flashing on the flanks for disc playback) but I did not find any lower cost alternative ... And, as already mentioned, the LEDs can already disconnect is more discreet.
