IBM Travelstar 40GNX 07N9481 20GB Laptop Hard Drive

IBM continues its rich tradition of producing mobile storage products with it's Travelstar 40GNX, a 9.5mm high, fifth generation 5400 rpm, hard disk drive for mobile computing. The innovative hard drive design combines AFC Media, Fluid Dynamic Bearing (FDB) motor technology, IBM Giant Magnetoresistive (GMR) heads, Partial Response Maximum Likelihood (PRML) digital channel, head load/unload technology, Enhanced Adaptive Battery Life ExtenderTM (ABLE) 3.0, and an ATA/100 interface. With this design, the Travelstar 40GNX provides exceptional storage capacity, performance, power management and quality required by today’s demanding notebook requirements.

Product Features:

  • 40GB mobile hard drive and the fifth-generation 5,400rpm model in the industry
    IBM Travelstar 40GNX 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
    • VCM acoustic dampening

    IBM Travelstar 40GNX incorporates state-of- the-art noise suppression technology for industry- leading quiet operation.
  • Fast Ultra-DMA 100 2.5-inch mobile hard drives
    IBM Travelstar 40GNX features industry- standard high data transfer rates to help ensure ultimate performance.
  • High max areal density of 34Gbits/sq.inch resulting in up to 20GB of capacity per disk
    IBM Travelstar 40GNX maximizes areal density to enable more data storage per disk in standard,compact packages.
  • Industry-leading operating shock rating (200Gs/2ms)for a 2.5-inch mobile hard drive
    IBM Travelstar 40GNX provides exceptional ruggedness to help withstand shock during read/write operations.
  • Antiferromagnetically coupled (AFC)media on all models
    The IBM Travelstar family incorporates AFC “pixie dust ” technology,allowing for higher areal density.
