PROJECT TITLE :
Enhancing internal parallelism of solid-state drives while balancing write loads across dies
To increase storage capacity and i/O bandwidth, trendy solid-state drives embed multiple NAND packages that consist of 1 or multiple dies in a very parallel design. Every die can method NAND browse/write/erase operations independently. A dynamic die binding technique for write requests that's intended to exploit this parallel processing capability is proposed. This scheme stripes data to idle dies first, and not like existing dynamic binding schemes, when idle dies are lacking it selects dies with rock bottom accumulated write hundreds, thereby achieving wear levelling by ensuring long-term write load balancing. Thus, it can prevent situations in which some dies are tired more quickly than others. A performance analysis demonstrates that our approach offers slightly better performance compared with an existing dynamic binding scheme and utterly resolves the problem of imbalanced write hundreds.
