Overview – Quantum BigFoot 2.1gb

Quantum Bigfoot™ 5.25-inch hard disk drives, designed for value-oriented personal computer systems, combine very high capacity with excellent cost-per-megabyte economics. Offered in formatted capacities of 1,286, 2,110, and 2,577 megabytes (MB) of storage, these products are particularly well-suited to multimedia systems and applications that require large storage capacities.

The Quantum Bigfoot drives’ ultra slim-line design, which measures 8 by 5.75 by 0.75 inches, fits into any available 5.25-inch bay in most modular PCs without any customization to system enclosures. Since Quantum Bigfoot drives mount exactly like a CD-ROM unit, installation is actually easier than a traditional 3.5-inch drive, since no brackets or mounting rails are required.

These products are engineered specifically to balance maximum storage capacity, consumer multimedia performance requirements, and attractive cost-per-MB economics. By applying field-proven components to the 5.25-inch form factor, Quantum also provides the highest levels of quality and reliability.

High-Performance Data Transfers

Quantum Bigfoot drives provide highspeed data transfers through a welldesigned, Fast ATA-2 interface. The combination of a 128-kilobyte buffer and the increased track capacities available with 5.25-inch disks allow these drives to meet the performance requirements of the newest generation of consumer PC systems. These features also result in improved sequential performance at the application level because, for any single transaction, there are fewer seeks and head switches. This speed particularly enhances multimedia playback and virtual memory use of the disk drive.

Quantum’s implementation of a Fast ATA-2 interface supports local-bus AT Programmed Input/Output (PIO) Mode 4 and Multiword DMA Mode 2 data transfers at speeds of up to 16.6 MB per second. Enhanced Quantum AutoTransfer™ technology takes advantage of the intelligent processing features of the drives and uses a proprietary ASIC design to speed data transfers by minimizing drive-to-host overhead delays.

Multiple AutoRead™ and Multiple AutoWrite™—industry-first solutions for increasing sequential data transfers—allow multiple-sector transfers for a given data request. This combination of firmware and hardware also enhances AutoTransfer capabilities.

Reliability and Versatility

Quantum Bigfoot drives meet the highest standards for data integrity. Automatic, double-burst, on-the-fly error detection and correction are implemented using an advanced custom ASIC and firmware.

These drives also come with an ATBus Cable Select™ feature that supports the latest Plug-and-Play ATA specifications. When combined with host system support,* this simplifies disk drive installation by automatically configuring the drive and eliminating the need for manual jumper settings. This feature is particularly beneficial for users who are upgrading their system through the addition of a second hard disk drive.

* Host system support is defined as Quantum’s Disk Manager Software (supplied with drive).
