Works perfectly. Easy to install. I got the cover of the DVD recorder (flakes easily) and placed it on the adapter (easily fits). The portable hard disc in the adapter (disc 2 = HHD). The SSD placed as the main disk (disk 1 = SDS). Installing the OS (Linux on USB key for me) SSD (much faster than mechanical HDD). SSD = improvement (start, speed, opening programs, Virtualbox, ...).
