摘要

The Flash Translation Layer (FTL) plays a crucial role for the performance and lifetime of SSDs. It has been difficult to evaluate different FTL strategies in real SSDs in the past, as the FTL has been deeply embedded into the SSD hardware. Recent host-based FTL architectures like ZNS now enable researchers to implement and evaluate new FTL strategies. In this paper, we evaluate the overhead of va...
