If you use Windows 7 to mirror a volume across an SSD drive and a mechanical hard drive, will the read performance be similar to a single SSD drive?
I.e. is Windows smart enough to read from them both and use the data that comes back first?

In my test with two conventional hard drives, read performance was as good as the fastest hard drive but write performance was as bad as the slowest.
(Note the scales are different.)
