I don't think there's anything spectacular here, but here are five 5 TB Toshiba drives and an SSD:

And here's an older machine that I learned I used the wrong SATA connector for:

Code:
   NOTE: A faster SATA drive is attached to a slower SATA link. You may add
         the /ident command-line option to display and identify the drive.

After fixing the problem. Not a life changing change on these older spinning drives, but it still feels tidier:

Code:

---- ----- ---------------------------- ------- ------- ------- ------- -------

 82  5.0TB ST5000DM000-1FK178            182.9   165.7   150.4   129.6    80.6 
 83  1.0TB Hitachi HDS721010CLA332       128.2    74.4    93.1    87.7    55.2

Maybe not life changing, but the 5.0TB disk is about 50% faster than it was. Not bad for a few seconds work swapping cables.

I think you're confusing the drives...drives 2 and 3 are swapped in the second run.
