A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1 GB = 230 = 1,073,741,824 bytes, and therefore shows less storage capacity. Available storage capacity will also be less if the computer includes one or more pre-installed operating systems, pre-installed software applications, or media content. Actual formatted capacity may vary. ** Free of brominated flame retardants (BFR) and polyvinyl chloride (PVC); hazardous halogens, antimony trioxide and red phosphorous also eliminated from all components in the MKxx55GSX drive series. *** Buffer space available to the user. **** S-ATA power management features applied.
