MK5055GSX (HDD2H21)
2.5" HDD 500GB*
The MK5055GSX 2.5-inch Hard Disk Drive offers quiet acoustics and enhanced durability, providing a solid storage solution for high-capacity mobile PCs, game consoles, printers and external storage. Advanced servo techniques combined with mechanical design changes minimize noise and make them nearly inaudible during operation.
Further design optimizations have boosted the durability of the MK5055GSX to provide industry-leading robustness against operating shock. An optional free-fall sensor (FFS) feature further protects user data against potentially hazardous external shock and vibration events.

* One Gigabyte (1 GB) 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 definition 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.
** 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.
