I have an HGST 7200 RPM 1 TB laptop drive that I have put in a USB 3.0 Enclosure and I am wondering if there are any performance penalties if I run the drive over USB 3.0 compared the 6 GBs SATA internal connection. Since USB 3.0 has a max rate of 5 Gbit/s it should not a problem I guess. But there has to be more to it as it is was not designed for HDD like the SATA interface. And the interface ovearhead? Since my encllouser supports UASP, it should not have any interface issues, will it? Here's a Benchmark I ran for my 7200 1Tb drive over USB 3.0, running with UASP. Is this the same kind of performance I would get in an internal SATA connection? What are the pros and cons of using an external UASP USB 3.0 encloser for an HDD? Thanks.
