When computers use less energy, they cost less to operate, thereby increasing a company's profits. It does not get any simpler than that. Fujitsu has once again answered the call to helping companies save money by saving power, while at the same time, helping the environment. Fujitsu is now shipping its third generation 2.5" 10K RPM and first generation 15K RPM Enterprise hard disk drives. These drives range from 36GB up to 147GB in capacity.

While today's computers offer higher processor speeds and more memory at a lower acquisition cost than ever before, they cost much more to operate. That's because while newer server-class computers are smaller and more powerful than before, their greater processing power and increased capacity for storage make them consume more power as they perform their work.

These increasingly powerful processors, larger-scale memory devices, emit more waste heat than earlier models. They have less space in which to dissipate heat, and that heat must dissipate through higher-volume fans. Furthermore, the additional heat dissipated into data centers has to be re-dissipated using more powerful air-cooling systems.

Adoption is Happening:
For nearly two years, a variety of Serial Attached SCSI (SAS) products has been available in the marketplace. In 2006, the hard disk drive (HDD) industry anticipates shipping as many as 2.5M to 3M enterprise products with SAS as the preferred interface. This will represent approximately ten percent of the overall enterprise hard disk drives shipped for the year. In parallel, it is evident that small form factor (SFF) SAS hard disk drives are continuing to gain momentum.

Serial Attached SCSI (SAS)/Serial ATA (SATA) compatibility produces unprecedented storage synergies and efficiencies, enabling enterprises to meet both performance and capacity requirements with a single SAS infrastructure. SAS drives deliver the speed, reliability and scalability demanded in high-availability enterprise environments, while high-capacity SATA nearline drives are purpose-built for bulk storage applications, combining low cost per GB and enhanced reliability.

And now the SAS value proposition grows even stronger with the arrival of small form factor (SFF) 2.5-inch enterprise drives. These drives are spearheading a new class of high-I/O-density storage solutions that facilitate rapid and cost-effective storage consolidation. SFF 2.5-inch drives are 70 percent smaller than conventional 3.5-inch 10K drives, enabling them to deliver 130-150 percent greater system performance in the same footprint. They also use 40 percent less power and run cooler, reducing airflow requirements and enabling greater storage density.
