New technology exceeds expectations

Travelstar E5K160, designed for demanding data-access applications, leverages Hitachi’s perpendicular magnetic recording (PMR) to deliver superior technology and reliability. Hitachi employs specific microcode to allow the Travelstar E5K160 to deliver 24 x 7 access to data. With capacities up to 160GB, industry-leading performance, low-power consumption and excellent shock resistance, the E5K160 can support the stringent demands of ”always-on” applications in lower transaction environments. The improved electronics design reduces the power consumption of this 5400 RPM drive to 10% below its industry-leading predecessor, and the E5K160 runs cooler than the competition. Hitachi has also implemented Thermal Fly-height Control (TFC) for improved error rates, and iridium-manganese-chromium (IrMnCr) read heads for improved reliability. This combination of attributes enables the Travelstar E5K160 to address the needs for rugged, reliable storage in non-stop environments.
