Wanted to see what the actual top speed of an mSATA SSD in an mSATA USB 3.0 enclosure might be, so went to a retail store with several top of the line laptops.

Tried 5 of the highest priced laptops they had and was surprised that only one was over 400 MB /s.  Even more surprised that 3 where barely over 100 MB / s.  And yes, the SSD was plugged into ports that were clearly marked with the 'SS' for USB 3.0.

Was using Crystal Disk Mark on one partition of the SSD to run tests on another partition of the SSD.

Any ideas for why these top dollar laptops had such poor USB 3.0 performance?

Guess it pays to test before you buy.

Crappy, outdated drivers from ~2013? Just a guess, but this happened to my Motherboard, Ethernet drivers after 3rd birthday to a new MB, no Win10 installator, set of new ones on producers website...

That was my first thought, since the retail shelf does get pretty outdated.
But still, never would have expected the USB 3.0 drivers on top of the line laptops to be that bad -- right out of the box.
Thanks
