45E7973 IBM 1TB 7.2k 3Gbps SATA HDD Technology – 45E7971, WD1002FBYS-05A6B0

Operating at 7200 RPM, the IBM 45E7973 offers better overall performance than slower-RPM, capacity-oriented drives at impressively low power-consumption rates. With five Advanced Power Management modes, a 36% reduction in watts during low-RPM idle mode, and using less than 1W during standby/sleep mode, the IBM 45E7973 can help data centers achieve lower AC power and HVAC requirements, freeing up precious headroom for growing enterprise needs.

  • Enhanced Rotational Vibration Safeguard (RVS) for robust performance in multi-drive environments
  • 24×7 enterprise-class duty cycle
  • Delivers proven reliability, with an MTBF of 1.2 million hours
  • Reduces energy and cooling costs, with the lowest power consumption of any nearline 3.5-inch drive

IBM 45E7973 1TB 7.2k 3Gbps SATA HDD Applications – 45E7971, WD1002FBYS-05A6B0

The IBM 45E7973 1TB 7.2k SATA HDD is best suited for higher-capacity environments to help realize cost and capacity benefits. Sequential access applications have a tendency to maximize any caching advantages of the storage system, and take advantage of the higher density SATA disk drives. In these applications, the speed at which the drive can transfer data from the platter has the greatest effect on overall performance. Thus, medium-to-large block and sequential I/O applications can reap the greatest benefits from the drive’s higher area-bit densities.
