IBM/Hitachi Travelstar 80GN IC25N080ATMR04 (08K0635) 80GB Laptop Hard Drive

Hitachi Travelstar 80GN IC25N080ATMR04 (08K0635) 80GB is a 9.5mm high 4200rpm 2.5-inch mobile hard disk drive.The Travelstar 80GN brings a 26th generation addition to the long line of Travelstar family drives. Its design combines AFC Media Fluid Dynamic Bearing(FDB) motor technology Giant Magneto resistive (GMR) heads Partial Response Maximum Likelihood (PRML) digital channel head load/unload technology Enhanced ADaptive Batter Life Extender (ABLE) 3.0 and an ATA/100 interface. With this design,the Travelstar 80GN provides exceptional quietness, storage capacity, performance,power management and quality required by today ís demanding notebook systems.


  • 26th generation of Travelstar hard drives
    Hitachi Travelstar 80GN has the industry-leading performance to enable mobile users to work with a new range of emerging storage-intensive applications.
  • Drive Noise Suppression System (DNSS)
    Fluid Dynamic Bearing (FDB) motors on all models
    Hitachi Travelstar 80GN incorporates state-of-the-art noise suppression technology for industry- motors leading quiet operation.
  • Fast Ultra-DMA 100 2.5-inch mobile hard drives
    HItachi Travelstar 80GN features industry-standard high data transfer rates to help ensure ultimate performance.
  • High max areal density of 70Gbits/sq.inch up to 40GB of capacity per disk
    Hitachi Travelstar 80GN maximizes areal density resulting in to enable more data storage per disk in standard compact packages.
  • Operational shock rating of (200Gs/2ms) for a 2.5-inch mobile hard drive
    Hitachi Travelstar 80GN provides exceptional ruggedness to help withstand shock during read/write operations.
  • Antiferromagnetically-coupled (AFC) media on all models
    The HItachi Travelstar family incorporates AFC "pixie dust" technology,allowing for higher areal density.
