You see a noticeable increase in the speed that the now playing list fills (with 512mb), and a slight increase in FTP speed.
You also get a small speed boost going from older 2Mb caches to 8+Mb's in today's drives.
So you may be better off waiting till after the upgrade to see what improvement you get just from the drive.

PS don't buy WD Caviar Blue as they don't work in S1's.
