[. . . ] QUANTUM BIGFOOT 1. 2AT/ 2. 1 / 2. 5AT AT Key Features High capacity (more than 1, 280 MB per disk) · 5. 25-inch, ultra slim-line (0. 75-inch-high) form factor · Fast ATA-2 PIO Mode 4 and Multiword DMA Mode 2 support · AutoTransfer technology · Multiple AutoRead/Multiple AutoWrite · High-Capacity Disk Drives for Value-Oriented Personal Computers Overview Quantum BigfootTM 5. 25-inch hard disk drives, designed for value-oriented personal computer systems, combine very high capacity with excellent cost-permegabyte 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. [. . . ] Multiple AutoReadTM and Multiple AutoWriteTM--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 SelectTM 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). 160-bit Reed Solomon double-burst ECC on-the-fly · Adaptive Segmented Buffer · DisCache® and WriteCache® firmware · Advanced Embedded Servo · S. M. A. R. T. (Self-Monitoring, Analysis, and Reporting Technology) Revision 2 Support · AT-Bus Cable Select · System-Controlled Power Modes · Defect Free Interface® firmware · DiskWareTM downloadable firmware · 300, 000-hour MTBF · 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 SPECIF IC ATIONS Quantum Bigfoot Form Factor Interface Formatted Capacity (MB1) 1. 2 2. 1 2. 5 Physical Specifications Dimensions--inches (mm) Width Length Height Weight--pounds (kg) 5. 75 (146. 05) 8. 0 (203. 2) 0. 75 (19. 05) 1. 55 (0. 711) 5. 75 (146. 05) 8. 0 (203. 2) 0. 75 (19. 05) 1. 64 (0. 752) 5. 75 (146. 05) 8. 0 (203. 2) 0. 75 (19. 05) 1. 64 (0. 752) 5. 25 inch (Ultra Slim-Line) Fast ATA-2 40-pin dual in-line 1, 286 2, 110 2, 577 Disk Drive Configuration Disks Heads/Recording Surfaces Tracks per Surface Sectors per Track Bytes per Sector Track Density (tpi) Max.
