Did my data from the old to the new SSD mirrored SSD using the supplied Samsung software. That was done in less than 10 minutes to went rapidly. Screw PC, old raus, new purely SSD, screw, finished! It's that fast.
I then led to the ATTO Disk Benchmark test, the hit me almost from the stool. But look at the data itself:
469 MB / s write
539 MB / s read!
And the positive: have again to roam for any virtual machines for testing!
