Lesson Outline
Lesson Summary
In 2001, the Advanced Technology Attachment, Parallel ATA, (PATA) interface
faced significant difficulties in achieving speeds greater than 100MB/sec.
Why SATA was Developed
• Lower Voltages Required
• Performance Roadmap
• Lower Pin Count
• Migration to Servers
• New Cables and
Connectors
• Hot-Plug Devices
• Reliability
Possible Software Compatibility
impact = Millions of computers
Possible Cost to Users =
Billions of $
Solution, adapt a Hardware
Change only high speed
interface that requires no
Software change for users.
