5,400 RPM
2.5-Inch SATA Hard Disk Drives
High Capacity, Energy Ecient
Solutions for a Multitude of
2.5-inch Applications
Toshiba’s MKxx76GSX Series 5,400 RPM hard disk drives
build upon the maturity of the Toshiba 320GB1 per-
platter architecture to oer the same big storage capacities
with enhanced quality and reliability. Five models in the
MKxx76GSX family deliver capacities spanning 160 to
640GB in the compact 2.5-inch form factor.
Durable, power ecient, and reliable the MKxx76GSX drive
series is ideal for notebook, all-in-one and EnergyStar® PCs,
printers, gaming consoles, video surveillance systems, external
storage devices and other computing applications. Massive
storage capacities as well as quieter and cooler operation make
the MKxx76GSX line an attractive, space-saving alternative
to desktop hard drives. Power consumption can be reduced
by more than 80% with the MKxx76GSX over like-capacity
3.5-inch hard disk drives.

One Terabyte (1TB) = 1,000 Gigabytes (GB). One Gigabyte (1GB) means 109 = 1,000,000,000
bytes using powers of 10. A computer operating system, however, reports storage capacity
using powers of 2 for the denition of 1GB = 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.
