since only comes in my old laptop HDD, I'm happy ... Those old laptop HDD, was replaced by an SSD which to test the USB 3.0 enclosure was operated herein. On Sata port gave the SanDisk SDSSDP128G around 477MB / s read and 362MB / s write. In the housing via the USB port 3 I got 100 MB / s both reading than writing. Because the old laptop drive anyway only about 60MB / s creates, suits me the completely ... As far as I am, except for the length of the already repeatedly criticized cable, satisfied because the price is very good (11,99) :-)
