You got that one right! I removed 2 GP models one being a 500gb added for testing 7 and later another 1tb drives for storage. Each Windows install on the 500gb then proved to have problems with any program you installed despite repeated clean installs.

Note the 500gb GP was almost removed from the old case and stuffed back into the external casings. The one 1tb while still in the new build was just replaced by a Sata III 1gb Black edition for the new and a noticable increase in access time has been seen. Both the GP and BE models see a 32mb cache as well as for the Sata II 1tb model bought in Dec.

The 1tb GP model was first bought and simply extracted from the casing and instaled internally for storage. But the reference to "Good to some degree, Certainly Better, and Best" would seem to fit the bill better for those three model lines. At times the GP even vanished from WE or was simply had to access even on the new build where it is now for ??? just how long remains to be seen.
