I just purchased this W510, and I love it!
I also purchased a Corsair F120 120GB SSD and a Patriot Gauntlet USB 3.0 enclosure for storage of files. In running initial tests on this drive with HD Tune Pro, I found the following:
1) Sequential read: Internal HDD starts off at ~97 MB/sec and tapers off to ~60% of that speed as the test runs out to the edge of the platter. SSD, on the other hand, is a constant ~94 MB/sec or so, and equals the performance of the HDD when the HDD is about at the 100GB mark (500GB drive).
2) Sequential write: Internal HDD is still just under 100 MB/sec to start, but the SSD only delivers about 50 MB/sec.
Now this is a newer Sandforce SSD capable of over 250 MB/sec transfer rates, so I know the bottleneck isn't the SSD. Also, I read test writeup here: http://www.guru3d.com/article/msi-star-usb-3-contr
Any ideas on what might be going on here? Can I actually expect higher performance? At this point, I'd be happy to match the performance of the internal hard drive!
My USB 3.0 controller driver is version 18.104.22.168, which I believe is current.
