Hybrid SSD HDD Boot Architecture for Fast OS Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computing devices face challenges in reducing boot time and latency associated with hard disk drives, and while solid state drives offer lower access times, they are expensive and lack flexibility in operating system changes.
Innovation Solution
A computer apparatus combining a hard disk drive and a solid state drive, where the solid state drive stores and provides the operating system for fast booting, allowing for cost-effective and flexible operating system selection by users through detachable portable drives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If solid state drives are used to store the operating system, then boot time is reduced, but cost increases
Solution Approach 1:
The storage system is segmented into two distinct drives: a solid state drive dedicated to storing the operating system and a hard disk drive for storing data files. This segmentation allows the system to achieve fast boot times by loading the OS from the SSD while maintaining cost-effectiveness by using the cheaper HDD for bulk storage, thus resolving the contradiction between reduced boot time and increased cost.
2Speed
If solid state drives replace hard disk drives, then access time is reduced, but flexibility in operating system changes is lost
Solution Approach 1:
The system implements dynamic flexibility by allowing users to easily replace or change the solid state drive containing the operating system. The computer apparatus is designed to accept different SSDs, enabling users to switch between different operating systems or update them independently without affecting the hard disk drive or other system components, thus maintaining both fast access times and adaptability.
3Loss of time
If preinstalled operating system is burnt into memory, then boot time is reduced, but flexibility in operating system selection is limited
Solution Approach 1:
The operating system is separated from the main system memory and stored on a removable solid state drive. This segmentation allows the OS to be quickly loaded at boot time (achieving fast boot performance) while simultaneously enabling users to change or replace the OS by simply swapping the SSD, thus resolving the contradiction between reduced boot time and limited flexibility.

AI summary
A fast booting computer apparatus includes one or more processors and a memory comprising a hard disk drive and a solid state drive coupled to the one or more processors. The one or more processors are configured to execute programmed instructions stored in the memory. The solid state drive is configured to store and provide the programmed instructions for an operating system for execution by the one or more processors when requested.
