Toshiba’s MKxx56GSY drive family of 7,200 RPM, 2.5-inch hard disk drives provide up to 500GB of capacity storage while improving system and application receptiveness. Top-of-the-line presentation, low-power utilization and field- confirmed sturdiness make the MKxx56GSY Series compatible for a wide diversity of data-intensive movable and stationary computing systems counting consumer and commercial notebook PCs, Energy Star, tiny and all-in-one desktops, as well as graphic and image rendering workstations.

This is a representative of the fast HDD series from Toshiba. It has two 250GB platters, a spindle speed of 7200 RPM, and 16 megabytes of cache memory. Toshiba has proclaimed a new 61 series of HDDs based on 320GB platters by this fall.
The MKxx56GSY continues Toshiba’s proposal in environmentally-conscious solutions by declining or eradicate the use of certain toxic, perilous or contentious chemicals in the drive. Toshiba’s purpose is to switch its whole line of hard disk drives to environmentally safer solutions. This is a 500GB model from Seagate’s new Constellation ES series. Its 1-terabyte cousin did very well in our recent HDD roundup.
