Drive Two

SSDs offer much faster speeds, are completely silent, produce far less heat, are lighter and more reliable than HDDs (Hard Disk Drives, these feature a physical disk that spins at 7200RPM)

So what's the catch? The price I'm afraid, SSDs are much more expensive so if on a budget use an SSD for your system drive and for your samples and stick with HDD for your projects drives. If budget does allow though, go for SSD throughout!
