HDD: 2TB (2TBx1) SATA-III 6.0Gb/s 64MB Cache 7200RPM HDD (Single Drive) <----- This is somewhat Decent
You need something around a SSD rather than a Regular drive for the best Possible use of AMD products Trust me I have built many computers before and you won't regret getting a SSD before a HDD. Reasons why?
Boot Time is as fast as possible
Game Load/Render at Maximum File transfers Uses CPU/SSD Transfer rate
Other than that go for a HDD, Your performance may Drop from inability to Maximize Utuility but that won't really matter much as it is from 60-100 Mb transfer Rate or 45-75 Frame rate.
