HGST Travelstar
Travelstar was a brand of 2.5-inch hard disk drives (HDD) that was manufactured by Western Digital. The brand was originally introduced by IBM in 1994 with the announcement of the Travelstar LP, a 2.5-inch 300MB 12.5 mm high HDD. IBM began shipping 2.5-inch HDDs in 1990 without this branding.1991 Disk/Trend Report- Rigid Disk Drives, Disk/Trend Inc., p. RSPEC-69 The brand was adopted and renamed to "HGST Travelstar" by HGST after it acquired IBM's HDD business in 2003 and continued for a while after HGST was acquired by Western Digital, but the HGST prefix is now defunct. These drives were typically used with laptop computers and small form factor desktop computers. Models are manufactured with capacities up to 1 TB, with rotational speeds of 5400 RPM or 7200 RPM and in 7mm or 9.5mm z-heights.

Hard Disk Drive
A hard disk drive (HDD), hard disk, hard drive, or fixed disk is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating platters coated with magnetic material. The platters are paired with magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored and retrieved in any order. HDDs are a type of non-volatile storage, retaining stored data when powered off. Modern HDDs are typically in the form of a small rectangular box. Introduced by IBM in 1956, HDDs were the dominant secondary storage device for general-purpose computers beginning in the early 1960s. HDDs maintained this position into the modern era of servers and personal computers, though personal computing devices produced in large volume, like cell phones and tablets, rely on ...

HGST
HGST, Inc. (Hitachi Global Storage Technologies) was a manufacturer of hard disk drives, solid-state drives, and external storage products and services. It was initially a subsidiary of Hitachi, formed through its acquisition of IBM's disk drive business. It was acquired by Western Digital in 2012. However, until October 2015, it was required to operate autonomously from the remainder of the company due to conditions imposed by Chinese regulators. Chinese regulators later permitted Western Digital to begin wider integration of HGST into its main business. By 2018, the HGST brand had been phased out, with its remaining products now marketed under the Western Digital name. History Hitachi Global Storage Technologies was founded on January 6, 2003, as a merger of the hard disk drive businesses of IBM and Hitachi. Hitachi paid IBM US$2.05 billion for its HDD business. On March 8, 2012, Western Digital (WD) acquired Hitachi Global Storage Technologies for $3.9 billion in cash and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laptop
A laptop, laptop computer, or notebook computer is a small, portable personal computer (PC) with a screen and alphanumeric keyboard. Laptops typically have a clam shell form factor with the screen mounted on the inside of the upper lid and the keyboard on the inside of the lower lid, although 2-in-1 PCs with a detachable keyboard are often marketed as laptops or as having a "laptop mode". Laptops are folded shut for transportation, and thus are suitable for mobile use. They are so named because they can be practically placed on a person's lap when being used. Today, laptops are used in a variety of settings, such as at work, in education, for playing games, web browsing, for personal multimedia, and for general home computer use. As of 2022, in American English, the terms ''laptop computer'' and ''notebook computer'' are used interchangeably; in other dialects of English, one or the other may be preferred. Although the terms ''notebook computers'' or ''notebooks'' or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desktop Computer
A desktop computer (often abbreviated desktop) is a personal computer designed for regular use at a single location on or near a desk due to its size and power requirements. The most common configuration has a case that houses the power supply, motherboard (a printed circuit board with a microprocessor as the central processing unit, memory, bus, certain peripherals and other electronic components), disk storage (usually one or more hard disk drives, solid state drives, optical disc drives, and in early models a floppy disk drive); a keyboard and mouse for input; and a computer monitor, speakers, and, often, a printer for output. The case may be oriented horizontally or vertically and placed either underneath, beside, or on top of a desk. Personal computers with their cases oriented vertically are referred to as towers. As the majority of cases offered since the mid-1990s are in this form factor, the term ''desktop'' has been retronymically used to refer to modern cases offer ...

Serial ATA
SATA (Serial AT Attachment) is a computer bus interface that connects host bus adapters to mass storage devices such as hard disk drives, optical drives, and solid-state drives. Serial ATA succeeded the earlier Parallel ATA (PATA) standard to become the predominant interface for storage devices. Serial ATA industry compatibility specifications originate from the Serial ATA International Organization (SATA-IO) which are then promulgated by the INCITS Technical Committee T13, AT Attachment (INCITS T13). History SATA was announced in 2000 in order to provide several advantages over the earlier PATA interface such as reduced cable size and cost (seven conductors instead of 40 or 80), native hot swapping, faster data transfer through higher signaling rates, and more efficient transfer through an (optional) I/O queuing protocol. Revision 1.0 of the specification was released in January 2003. Serial ATA industry compatibility specifications originate from the Serial ATA Internat ...

Parallel ATA
Parallel ATA (PATA), originally , also known as IDE, is a standard interface designed for IBM PC-compatible computers. It was first developed by Western Digital and Compaq in 1986 for compatible hard drives and CD or DVD drives. The connection is used for storage devices such as hard disk drives, floppy disk drives, and optical disc drives in computers. The standard is maintained by the X3/INCITS committee. It uses the underlying (ATA) and Packet Interface ( ATAPI) standards. The Parallel ATA standard is the result of a long history of incremental technical development, which began with the original AT Attachment interface, developed for use in early PC AT equipment. The ATA interface itself evolved in several stages from Western Digital's original Integrated Drive Electronics (IDE) interface. As a result, many near-synonyms for ATA/ATAPI and its previous incarnations are still in common informal use, in particular Extended IDE (EIDE) and Ultra ATA (UATA). After the introd ...

Deskstar
The Deskstar was the name of a product line of computer hard disk drives. It was originally announced by IBM in October 1994. The line was continued by Hitachi when in 2003 it bought IBM's hard disk drive division and renamed it Hitachi Global Storage Technologies. In 2012 Hitachi sold the division to Western Digital who continued the drive product line brand as HGST Deskstar. In 2018 Western Digital began winding down the HGST brand and as of 2020 it is defunct. The first Deskstar product produced by IBM was the DALA-3540; the last was the 180GXP HGST continued the product line after the acquisition, selling the Deskstar 120GXP and Deskstar 180GXP under the HGST brand for a short time and selling new models thereafter. The unreliable IBM Deskstar 75GXP product became notorious as the " Deathstar" (only one of at least twenty IBM products in the Deskstar family).

Ultrastar (WD Brand)
Ultrastar is a Western Digital brand of high performance 3.5-inch hard disk drives (HDDs) and solid-state drives (SSDs). The brand was originally introduced by IBM in 1994 for HDDs and was adopted and renamed to "HGST Ultrastar" by HGST after it acquired IBM's HDD business in 2003. Western Digital continued using the HGST prefix for a while after it acquired HGST in 2012 but the HGST prefix is now defunct. Some Ultrastar HDDs were sold under both HGST and WD branding (e.g. the HGST Ultrastar He10 and WD Ultrastar HC510 are the same models of HDD). These drives are typically used with enterprise computer systems. The two 1994 models, the 10.8 GB Ultrastar2 and the 8.7 GB Ultrastar2 XP were offered with a variety of interfaces including Fast SCSI, Fast-Wide SCSI, SCA 80-pin connectors, and Serial Storage Architecture. Evaluations units were available in the third quarter of 1995. Current HDD models are offered with capacities up to 20 TB and with SATA or SAS interfaces. Cur ...

Computer Storage Devices
Computer data storage is a technology consisting of computer components and recording media that are used to retain digital data. It is a core function and fundamental component of computers. The central processing unit (CPU) of a computer is what manipulates data by performing computations. In practice, almost all computers use a storage hierarchy, which puts fast but expensive and small storage options close to the CPU and slower but less expensive and larger options further away. Generally, the fast volatile technologies (which lose data when off power) are referred to as "memory", while slower persistent technologies are referred to as "storage". Even the first computer designs, Charles Babbage's Analytical Engine and Percy Ludgate's Analytical Machine, clearly distinguished between processing and memory (Babbage stored numbers as rotations of gears, while Ludgate stored numbers as displacements of rods in shuttles). This distinction was extended in the Von Neumann arch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Divested IBM Products
In finance and economics, divestment or divestiture is the reduction of some kind of asset for financial, ethical, or political objectives or sale of an existing business by a firm. A divestment is the opposite of an investment. Divestiture is an adaptive change and adjustment of a company's ownership and business portfolio made to confront with internal and external changes. Motives Firms may have several motives for divestitures: # a firm may divest (sell) businesses that are not part of its core operations so that it can focus on what it does best. For example, Eastman Kodak, Ford Motor Company, Future Group and many other firms have sold various businesses that were not closely related to their core businesses. # to obtain funds. Divestitures generate funds for the firm because it is selling one of its businesses in exchange for cash. For example, CSX Corporation made divestitures to focus on its core railroad business and also to obtain funds so that it could pay off some ...
