摘要

NAND固态硬盘因其性能的提高和成本的降低而得到广泛应用。然而，它们的性能行为是复杂的。本文探讨了格式化后操作积累与性能之间的关系，主要表明格式化后对未写区域的写入会降低读性能。作为进一步的讨论，我们还提出了通过将读取性能近似为两个变量的二次函数来建模的结果，并表明这种建模方法可以估计性能。

Investigating Weird Latency Deterioration of Solid-state Drives

NAND SSDs are widely used because of their improved performance and decreased cost. However, their performance behavior is complex. In this paper, we explore the relationship between the accumulation of operations after formatting and performance, and show mainly that writing to the unwritten area after formatting degrades read performance. As a further discussion, we also present the results of modeling read performance by approximating it as a quadratic function of two variables, and show that this modeling method can estimate performance.
