Abstract

Current high performance server class disk drives used in the enterprise and workstation environment are all packaged in a standard 3.5" form factor. The devices currently available all require approximately 12-19 Watts of operational power. Recording technology has advanced to the point that the available capacity on a 3.5" device far exceeds the needs of most customers and applications. Therefore, a trend has developed in the industry of producing devices with fewer heads and disks.

High Performance Server Class Disk Drive packaged in a reduced size form factor

  Current high performance server class disk drives used in the enterprise and workstation environment are all packaged in a standard 3.5" form factor. The devices currently available all require approximately 12-19 Watts of operational power. Recording technology has advanced to the point that the available capacity on a 3.5" device far exceeds the needs of most customers and applications. Therefore, a trend has developed in the industry of producing devices with fewer heads and disks.

Based in this, what is proposed is a device of server class performance and reliability, but packaged in a much smaller volume. The capacity offered would be reduced from that available in 3.5" servers, which reduces the required operational power. Specifically, what is proposed is a serve class drive configured to 2.5" form factor (100 mm x 70 mm). A variety of Z height can be accomplished (9.5 mm, 12.7 mm, 15 mm for example) by varying the number of disks used. The capacity and operational power of such a device is roughly 1/2 of traditional 3.5" servers.

The reduced size and power of the proposed device offers advantages in several applications. The smaller device can achieve higher packaging density for applications that value small space (blade servers, RAID in a box, 1U based drive bays). The lower power per device is attractive in high end workstations where increasing processor power needs can be offset by reduced HDD power consumption.

The smaller size of the device also improves the mechanical dynamics of the system relative to a normal 3.5" device, so higher track densities can be realized. Ultimate costs are also lower for a smaller device.

The specific device proposed here offers 2 significant advantages over the expected competitive drives of the size:
1) The PCB of the proposed device has been configured to allow the largest possibl...
