Seagate ST446452W manual

Elite 47 Installation Guide, Rev. B

•Do not remove any circuit boards from the drive. Return the entire drive for depot repair if any circuit board is defective. Removal of circuit boards by personnel not performing depot repair will damage components and may void the warranty.

•Return the entire drive for depot repair if the HDA is defective.

•Do not attempt to disassemble the HDA. It is not field repair- able. If the sealed HDA is opened by personnel not performing depot repair, this will damage components and void the warranty.

As a component, this drive is designed to be installed and oper- ated in accordance with UL1950, EN60950, CSA C22.2 950- M89, and VDE0805.

Seagate takes all reasonable steps to ensure that its products are certifiable to currently accepted standards. Typical applica- tions of these disc drives include customer packaging and sub- system design. Safety agencies conditionally certify component assemblies, such as the Elite disc drive, based on their final acceptability in the end-use product. The subsystem designers are responsible for meeting these conditions of acceptability in obtaining safety-regulatory agency compliance in their end-use products and for certifying where required by law. A necessary part of meeting safety requirements is the provision for overcur- rent protection on drive SELV supply voltages.

This unit is a component part and as such is not meant to com- ply with FCC or similar national requirements as a stand-alone unit. Engineering radiated emissions test results are available through the Seagate Safety Department to assist the subsystem designer.

ST446452W specifications

The Seagate ST446452W is a notable entry in the world of hard drives, particularly renowned for its application in enterprise storage solutions during the mid-1990s. Designed primarily for servers and workstations, this drive was part of Seagate's formidable lineup, catering to business needs where reliability and performance were paramount.

With a physical size of 3.5 inches, the ST446452W hosts a storage capacity of 4.5 GB— an impressive figure for its time. This capacity enabled enterprises to store significant amounts of data, including critical applications and databases. The drive employs the SCSI (Small Computer System Interface) interface, specifically the SCSI-2 standard, which was commonplace during that era, allowing for speedy data transfer rates and the ability to connect multiple drives in a single setup.

The Seagate ST446452W features a rotational speed of 7200 RPM, contributing to its performance efficiency and response times. This speed, combined with an average seek time of around 9 milliseconds, positioned the ST446452W as a competitive option for database applications, file servers, and other data-intensive tasks.

One of the key technologies employed in the ST446452W is the use of magneto-resistive (MR) head technology. This advancement allowed for improved data density, ultimately enhancing the drive’s ability to read and write data at lower error rates. The drive also features a buffer cache, which serves to improve data throughput by temporarily storing frequently accessed data, minimizing seek times.

With its robust construction and reputation for reliability, the Seagate ST446452W proved to be a trusted choice for IT professionals seeking longevity in their storage solutions. Its design included features such as internal shock mounting and thermal management systems to ensure optimal performance under various conditions. These characteristics made the ST446452W an ideal candidate for mission-critical applications where downtime needed to be minimized.

In conclusion, the Seagate ST446452W encapsulates the technological advancements and engineering prowess of its time. Its integration of SCSI interface technology, high RPM speeds, and innovative data management features cemented its place in the legacy of data storage solutions, laying groundwork for subsequent generations of hard drives. Though it may be considered obsolete in today’s context, the ST446452W remains a significant reference point in the evolution of hard drive technologies.
