So what gives?
As I understand it, USB 3.0 is supposed to be 10 times faster than 2.0.
I have two external 2.5 hard drives, exactly the same...both 250gb drives. One is in a 2.0 external case, the other in a 3.0 external case.
I just installed a PCI-E USB 3.0 card reader in my old Gateway E4610. All seems to work fine.
However, when I copy a 10gb folder from my desktop to the USB 2.0 drive, using a USB 2.0 port, I get transfer rates of about 25mb/sec.
Doing the same thing with the same folder, except using the USB 3.0 enclosure with the new 3.0 port, I only get transfer rates of about 61mb/sec.
How is this 10 times faster? It isn't...it is only a little better than double the speed....and I repeated the test several times.
