That's a normal Raptor not a Velociraptor, I use one myself as a boot drive and for some apps and stuff. All my games and Steam folder are on another drive, the only downside is it takes a few seconds for the drive to spin up when first loading a game as unlike the OS drive there's no need for it to spin up on boot. Access times are apparently what's important for an OS drive and the last time I looked at HDD spec's 7200RPM drives access times seem to have peaked when they had an areal density of 334gb platters(if I re-call correctly around 13ms, compared to around 8ms for a Raptor). I would only bother messing around with moving the OS to another drive if it was an SSD.
