Toshiba MK1255GSX 120GB 2.5-Inch Hard Drive Specifications And Datasheet

Toshiba MK1255GSX 120GB 2.5-Inch Hard Drive

Description

The MKxx55GSX Series of 5,400 RPM, 2.5-inch hard disk drives offers up to one- half terabyte in capacity with quiet acoustics and enhanced durability, providing a solid storage solution for mobile and stationary PCs, game consoles, printers, external storage devices as well as set-top boxes, personal video recorders, and surveillance systems. Toshiba’s advanced servo techniques and mechanical design minimize drive acoustics, making them nearly inaudible during operation. The 320GB1, 160GB1, and 120GB1 in particular, perform close to the threshold of human hearing.

Further design optimizations boost the durability of the MKxx55GSX line-up, providing industry-leading robustness against shock while the drives are in operation. An operational free-fall sensor (FFS) feature further protects the drive and user data against potential damage from shock, vibration, and rough handling. The MKxx55GSX products support a 3 Gb/sec data transfer rate and have passed testing by the Serial ATA International Organization (SATA-IO) for SATA interoperability.

1. 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 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.
2. A small portion of buffer memory is used for drive firmware control.
3. SATA PHY is in slumber mode.
4. Halogen-free as defined by levels of chlorine (CL) and bromine (Br) or a compound in which they are combined reduced to be less than the standards of IEC61249-2-21:2003, as stated below: Chlorine: less than 900ppm, Bromine: less than 900ppm, Chlorine + bromine: less than 1500ppm
