Introduction

The Marathon 810 (ST9816AG) provides high storage capacity in a small, low-profile hard disc drive.

Key features:

• SafeRite shock protection

• Low power consumption

• Compact, MCC-compatible form-factor

• Quiet operation

• Advanced partial-response, maximum-likelihood (PRML) read channel

• Supports logical block addressing

• Supports PIO modes 0, 1, 2, 3 and 4, and DMA modes 0, 1 and 2.

• High instant aneous data-transfer r ates (up to 16.6 Mbytes per s econd

using PIO mode 4 and DMA mode 2).

• Fast microprocessor for lower command overhead

• 120-Kbyte multisegmented adaptive cache

• Advanced caching and on-the-fly error-correction algorithms

• Supports Read Multiple and Write Multiple commands

• Supports autodetection of master/slave drives using cable select and

DASP– signals.
