Product Features

Functional / Interface

Maxtor DiamondMax™ Plus 5120 hard drives contain all necessary mechanical and electronic parts to interpret control signals and commands from an AT-compatible host computer. See Section 3 Product Specifications, for complete drive specifications.

Zone Density Recording

The disk capacity is increased with bit density management – common with Zone Density Recording. Each disk surface is divided into 16 circumferential zones. All tracks within a given zone contain a constant number of data sectors. The number of data sectors per track varies in different zones; the outermost zone contains the largest number of data sectors and the innermost contains the fewest.

Read/Write Multiple Mode

This mode is implemented per ANSI ATA/ATAPI-4 specification. Read/Write Multiple allows the host to transfer a set number of sectors without an interrupt request between them, reducing transfer process overhead and improving host performance.

UltraDMA - Mode 2

Maxtor DiamondMax Plus 5120 hard drives fully comply with the new ANSI Ultra DMA protocol, which greatly improves overall AT interface performance by significantly improving burst and sustained data throughput.

Multi-word DMA (EISA Type B) - Mode 2

Supports multi-word Direct Memory Access (DMA) EISA Type B mode transfers.

Sector Address Translation

All DiamondMax Plus 5120 drives feature a universal translate mode. In an AT/EISA-class system, the drive may be configured to any specified combination of cylinders, heads and sectors (within the range of the drive's formatted capacity). DiamondMax Plus 5120 drives power-up in a translate mode:
