For complement of information :
The SSD used is a Samsung 850 Pro 256 GB and the case is a Satechi ST-TCDEM.
Write rates were high at the start of the copy (450 MB/sec then dropped before
the crash to +/- 30 Mb/sec).
Restoring the disk image with this same SSD but integrated in a Delock USB 3
Type A case to a USB A socket on my computer works correctly with a transfer
rate of 60 to 90 MB/s.
The same SSD still plugged into the Delock USB 3 Type A box but connected to my
machine on a USB C port completes the restoration of the image with a constant
transfer rate of +/- 41MB/sec.
Regards.
