Quantum Bigfoot

Last updated

The Quantum Bigfoot brand was a series of hard disk drives produced by Quantum Corp. from 1996 through the late 1990s. The Bigfoot series was notable for deviating from the standard form factor for hard drives. While most desktop hard drives at that time used a 3.5-inch physical format, Quantum Bigfoot drives used a larger 5.25-inch form factor more commonly seen in older hard drives, CD-ROM and other optical disc drives. This form factor allowed Quantum to increase the capacity of their hard drives without an increase in data density, thus lowering costs compared to a 3.5-inch drive with the same capacity. It also allowed manufacturers and owners to install the hard drive above or below the optical drive in the computer, as the typical computer had multiple 5.25-inch bays.

Overview

The main rationale behind the use of the 5.25-inch form factor was that the typical PC user already owns cases that supports 5.25-inch drives, and by using lower data densities and fewer moving parts, Quantum was able to deliver the products at lower prices, thus more competitively. [1]

Initially, performance in the Bigfoot drives generally lagged behind most other drives of the era, [2] but the large data capacities earned inclusion in many OEM PCs such as ones manufactured by Compaq and HP, [3] as well as popularity with the PC enthusiast community. IBM also used Bigfoot drives in some of their Aptiva PCs even though they were also a major manufacturer of hard drives. [4] Over time, the data density (and therefore the overall capacity) of the drives increased, culminating in the 19.2 GB Bigfoot TS, easily the largest consumer-grade drive available at its release. A side effect of the increased data density was an increase in speed, moving the Bigfoot to middle-of-the-pack status amongst its contemporaries. Unfortunately, the increased manufacturing cost associated with the higher density also caused an increase in price, moving the Bigfoot towards a premium price. [5] Over time, increased prices combined with stiff competition caused sales of the drives to decline, leading to the line being discontinued in the late 1990s. [6]

Bigfoot drives were produced by a variety of different plants in Malaysia, Singapore, Japan and other locations. They were among the first to support Logical Block Addressing (LBA) and Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T.) monitoring.

Series

Four distinct series of Quantum Bigfoot drives were produced over time, with differences in capacity, spindle speed, access time and supported interface speed.

Quantum Bigfoot (original series)

The first generation Quantum Bigfoot drives were introduced around May 1996 [7] and offered in capacities of 1.2 GB (1 platter, 2 heads) and 2.5 GB (2 platters, 4 heads), [8] with suggested retail prices of $225 and $370 respectively. These drives offered only ATA-2 PIO Mode 4 and DMA mode 2 support (16.6 MB/s) and had an average seek time of 15 ms. Actual transfer rate from the platters was much lower, measured at 813 KB/s by PC Magazine using Disk WinMark 96, slower than a same-capacity/similar-capacityQuantum Fireball (3.5") drive, which delivered 1170 KB/s. [9]

Quantum Bigfoot CY

The second series was the Quantum Bigfoot CY series, introduced around December 1996. [10] Bigfoot CY drives shared the characteristics of a 3,600 RPM spindle speed and an ATA-2 interface connection. These drives had one to three 2.1 GB platters, [11] and were produced in capacities of 2.1 GB, 4.3 GB and 6.4 GB. [10] [12] Their access time was advertised as being "as low as 12ms," [12] and they had 128 KB of cache. [13] The suggested retail prices were $224, $310 and $395, respectively. [10] The largest drive of the CY series could transfer about 6 MB/sec from the platters when tested with hdparm -t in Linux. [14]

Quantum Bigfoot TX

The third series of Bigfoot drives was known as the Quantum Bigfoot TX series. This series increased the drives' spindle speed to 4,000 RPM and upgraded their interface capabilities to ATA-66. These drives carried the higher capacities of 4 GB, 6 GB, 8 GB and 12 GB. Like the CY series, access time was advertised as under 12 ms. The 12 GB model is noteworthy for being the first hard drive to attain a capacity in the double digits of gigabytes. Quantum claimed that these drives could outperform many of the 3.5-inch drives on the market at the time. [15]

Quantum Bigfoot TS

The fourth and final series of Quantum Bigfoot drives produced was the Bigfoot TS series. This series retained the spindle speed and interface speed of its predecessor. The main performance enhancement was a reduction in access time, to "less than 10.5 ms." It was produced in capacities of 6.4 GB, 8.4 GB, 10.0 GB, 12.7 GB and 19.2 GB. [16]

With this series, Quantum again claimed to have the highest capacity on the market with its 19.2 GB model. These drives had a new "shock protection system" designed to make the drives more resilient to physical shock, which Quantum called "one of the leading killers of disk drives." StorageReview found that this series was significantly faster than the TX series, though not as fast as most 3.5-inch drives available at the time. They also found it to be significantly louder than the TX series during use.

A floppy disk or floppy diskette is an obsolescent type of disk storage composed of a thin and flexible disk of a magnetic storage medium in a square or nearly square plastic enclosure lined with a fabric that removes dust particles from the spinning disk. Floppy disks store digital data which can be read and written when the disk is inserted into a floppy disk drive (FDD) connected to or inside a computer or other device.

<span class="mw-page-title-main">Hard disk drive</span> Electro-mechanical data storage device

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.

IBM manufactured magnetic disk storage devices from 1956 to 2003, when it sold its hard disk drive business to Hitachi. Both the hard disk drive (HDD) and floppy disk drive (FDD) were invented by IBM and as such IBM's employees were responsible for many of the innovations in these products and their technologies. The basic mechanical arrangement of hard disk drives has not changed since the IBM 1301. Disk drive performance and characteristics are measured by the same standards now as they were in the 1950s. Few products in history have enjoyed such spectacular declines in cost and physical size along with equally dramatic improvements in capacity and performance.

Density is a measure of the quantity of information bits that can be stored on a given length of track, area of surface, or in a given volume of a computer storage medium. Generally, higher density is more desirable, for it allows more data to be stored in the same physical space. Density therefore has a direct relationship to storage capacity of a given medium. Density also generally affects the performance within a particular medium, as well as price.

Perpendicular recording, also known as conventional magnetic recording (CMR), is a technology for data recording on magnetic media, particularly hard disks. It was first proven advantageous in 1976 by Shun-ichi Iwasaki, then professor of the Tohoku University in Japan, and first commercially implemented in 2005. The first industry-standard demonstration showing unprecedented advantage of PMR over longitudinal magnetic recording (LMR) at nanoscale dimensions was made in 1998 at IBM Almaden Research Center in collaboration with researchers of Data Storage Systems Center (DSSC) – a National Science Foundation (NSF) Engineering Research Center (ERCs) at Carnegie Mellon University (CMU).

In 1953, IBM recognized the immediate application for what it termed a "Random Access File" having high capacity and rapid random access at a relatively low cost. After considering technologies such as wire matrices, rod arrays, drums, drum arrays, etc., the engineers at IBM's San Jose California laboratory invented the hard disk drive. The disk drive created a new level in the computer data hierarchy, then termed Random Access Storage but today known as secondary storage, less expensive and slower than main memory but faster and more expensive than tape drives.
