Introduction
The Marathon 630sl prov ides high storage capacity in a smal l, low-profile hard disc drive.
Key Features:
• Low power consumption
• Low profile (12.75 mm max. height)
• Compact, MCC-compatible form-factor
• Quiet operation
• SafeRite shock protection (optional: ST9630AG only)
• Supports PIO modes 0, 1, 2, 3 and 4; also supports 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.
