Ah, that makes sense, if you look or read about any of these External USB 3.0 drives, with the fastest Hard drive and the the best system, they will only read and write at 3X the speed of a USB 2.0 external hard drive. Most USB 2.0 external hard drives, the portables like the WD Passport , or the Seagate 3.0.
Here is a review from Newegg. I even get better transfer rates than this.
Rating: 5/5USB 3.0 Hard Drive Very Speedy
Pros: Faster then what I thought it was going to be. Transfer test with H2testw 9.76gb in 122 seconds. So I am very happy.
USB 3.0 both ways 9.76gb in 122 seconds
Write Speed: 82.7 MByte/s
Read Speed: 82.8 MByte/s
USB 2.0 9.76gb Write 313 seconds Read 290 seconds
Write Speed: 31.9 MByte/s
Read Speed: 34.4 MByte/s
Other Thoughts: I wish Western Digital would put the rpm of there Portable Hard Drive on the box. I think it's 5400. Either way I am very happy with the performance
