Here's a more recent test:
http://www.anandtech.com/show/4020/ocz-vertex-plus-preview-introducing-the-indilinx-martini/3

That shows several consumer grade SSD's and a 600GB VelociRaptor, its 
200+ vs 140MB/sec. I'm not sure how recent 15k rpm sas disks would do, 
nor do I know how recent server grade SSD's would behave. But if we 
assume similar gains for both, its still in favor of SSD's :-)

Best regards,
