Introduction

The Marathon 810sl provides high storage capacity in a small, lowprofile hard disc drive. This drive is available in two models: the standard model ST9810A, and the ST9810AG, which includes SafeRite shock protection.

Key Features:

• Low power consumption

• Low profile (12.75-mm high); compact, MCC-com patible form- fact or

• Quiet operation

• SafeRite shock protection (optional; ST9810AG only)

• Supports PIO modes 0, 1, 2, 3 and 4, as well as single-word and

multiword DMA modes 0, 1 and 2.

• High instantaneous data-transfer rat es (up to 16.6 Mbytes per second) using PIO mode 4 and DMA mode 2.

• 120-Kbyte adaptive multisegmented cache

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

• Supports Read/Write Multiple commands

• Supports autodetection of master/slave drives using cable select

(CSEL) signal.
