Flash-based Solid-State Drives (SSDs) are rapidly becoming the mainstream solution in the storage panorama thanks to their ruggedness, high performance and reliability. To guarantee the demanding reliability requirements, it is mandatory to embed complex Error Correction Codes (ECCs) and advanced read algorithms. These countermeasures induce an overall performance degradation and hence a non trivial reliability-performance trade-off arises. This work explores such trade-off in a qualitative manner.

Abstract
Flash-based Solid-State Drives (SSDs) are rapidly becoming the mainstream solution in the storage panorama thanks to their ruggedness, high performance and reliability. To guarantee the demanding reliability requirements, it is mandatory to embed complex Error Correction Codes (ECCs) and advanced read algorithms. These countermeasures induce an overall performance degradation and hence a non trivial reliability-performance trade-off arises. This work explores such trade-off in a qualitative manner.File in questo prodotto:
