As soon Ordering and soon received but soon disappointed. If fpnctionne object, you can not say that this one really is at the top. Indeed when we stopped by a disc paneau Mac both are stopped and set error. When pluge two drives those are not working really well and stop from time to time (the mac told me that they were abnormally unpluge). Short end this is not the miracle product I expected. Still money wasted.
And in addition the seller did not respond to messages sent, so no opportunity to be reimbursed would be it a SCAM.
