This is indeed curious....I saw this same thing on the old mobo, so I
don't think that's the issue.
As for caching, that's an idea. But would that not imply that whatever
runs second would benefit more than what runs first (so that they
caching can happen)?

USB 3.0 has a theoretical capacity of 5.0gb/s, while SATA 3gb/s is...just

3gb/s, so I suspect whatever you're seeing is as a result of caching or
something like that. USB is also far more processor intensive and has a lot
more overhead, so all else being equal, if you can't saturate SATA, native
SATA will be faster.

Subject: [H] USB 3.0 faster than SATA 3Gb/s on HD?
Is that right? I have a 1 TB drive in a usb3.0 enclosure running off my
mobo.
Using CrystalDiskMark, I find that the read/write performance is faster to
a
usb 3.0 drive than to an internal drive on a SATA port. In some cases
almost a
factor of 2, but not generally.
Is that right?
How does esata compare? I currently don't have an esata enclosure hooked
up so I can't test.
