Capacity (GB) - One GB is equal to one billion bytes and one TB equals 1,000GB (one trillion bytes) when referring to hard drive capacity. Accessible capacity may be less.
Data Buffer (MB) - Portion of buffer capacity used for drive firmware
Availability - Intended for low duty cycle, non mission-critical applications in PC, gaming and external storage environments, which may vary from application to application. Note that customer environments may vary from application to application.
