Using Aconis True Image 2011, it takes about 25 minutes to restore my Windows 7 x64 Ultimate (about 45GB) to my SSD, OCZ Vertex 2..
I normally use another Windows 7 install on a standard hard drive to accomplish this but I have also used the Acronis bootable media as well.
I must say that I have only restored my system 4 times total, so far.
