Previously I had a cheap part, which was not optimized for SATA 3. This SATA HDDs have 2 works fine when converting to a second SSD (Samsung 840 EVO 1TB) there were, however, very weird problems. I was able to read data, but not write data (was very strange, different error messages). Hab first thought the new SSD has a problem. Fortunately, I have read the reviews on Amazon, the cheaper Adapter SATA 3 often causes problems. By hardwrk adapter is now all Top. The mounting ears are in the right place, so he will not budge in the Mac, the SSD is screwed into the adapter and is therefore immovable. For the plate tighten in the adapter, however, you need a small (0), long, thin Phillips screwdriver, as set screws must be screwed through tiny holes. A normal bit does not fit in any case. Speed with built-up Samsung 840 EVO 1TB: 392 MB / s write, 510 MB / s read (Blackmagic Design Disk Speed Test) Copy RealTest 14.5 GB virtual machine from system disk (Samsung 840 Pro) on data plate: 26 s => 550 MB / s Even a small note for the producer: The very chic stickers are in the installed state of the adapter unfortunately on the bottom ;-) (probably therefore is the sticker set in)
