Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional hard disk drives are prone to mechanical failure due to moving components, necessitating the development of more reliable storage solutions that offer increased storage capacity and efficient data management.
Innovation Solution
A memory storage device comprising a motherboard with multiple solid-state drives (SSDs) that include a storage controller for managing data distribution between primary and redundant allocations, with error detection and remapping capabilities to ensure data integrity and reliability, and visual indicators for easy maintenance and error identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional hard disk drives are used, then storage capacity can be provided, but mechanical failure occurs due to moving components
Solution Approach 1:
The patent replaces traditional mechanical hard disk drives with solid-state drives that have no moving parts. The storage device uses SSDs coupled to a motherboard, eliminating mechanical components entirely while maintaining storage capacity and improving reliability.
2Quantity of substance
If multiple solid-state drives are coupled to the motherboard, then storage capacity is increased, but device complexity increases
Solution Approach 1:
The storage system is divided into multiple independent solid-state drives that can be individually managed. Each SSD has its own controller, allowing independent operation and failure isolation. The drives are arranged in rows on both sides of the motherboard, enabling modular expansion.
Solution Approach 2:
Multiple solid-state drives are combined into a single storage array that presents a unified interface. The drives work together to provide increased storage capacity while sharing common control and management infrastructure through the motherboard.
3Reliability
If redundant storage allocation is implemented, then data integrity is improved, but storage capacity is reduced
Solution Approach 1:
The system pre-allocates redundant storage space before failures occur. When an error condition is detected in a primary storage allocation, the redundant allocation is already in place to receive the data, enabling immediate failover without capacity loss.
Solution Approach 2:
The system dynamically manages redundant storage by monitoring drive health and only activating redundancy when failures occur. The redundant storage is made available to replace failed drives, recovering capacity as drives fail and are replaced.

AI summary
Certain embodiments may relate to providing increased storage capacity. For instance, a memory storage device may include a motherboard with an external communication interface. The memory storage device may also include a multiple solid-state drives coupled to the motherboard in communication with the external communication interface. Each of the plurality of solid-state drives may include a respective storage controller to manage the distribution of data during a write or read operation to a combination of a primary storage allocation and a redundant storage allocation. The redundant storage allocation may be included in the combination in response to detecting an error condition associated with at least a portion of the primary storage allocation.
