server hardware upgrade – SSD

It seems my server is getting old.  It typically runs Windows 7 64-bit with a non-raid cloned (redundant) OS disc, 1.5TB storage disc (pics, videos, teaching material, etc.), and 3TB redundant backup of everything.  Just tonight I switched over to a Solid State Drive (SSD) for the OS.  Can you notice any speed difference?  Hope so.  Been eating up HDDs the past year – 3 in total.  So hopefully this will help.
