Should i upgrade from ATA?

[Casej18]

Hey guys,
I was wondering if i will see any difference with a SATA HD over my ATA HD. Is the difference to a raptor SATA HD that noticable? I have no idea so let me know

In short, it depends what you're doing. Playing games, yes. Almost anything else, no.

Edit: or at least not as big an increase in speed as in cost.
