The Unwritten Contract of Solid State Drives
We perform a detailed vertical analysis of application performance atop a range of modern file systems and SSD FTLs.
We formalize the “unwritten contract” that clients of SSDs
should follow to obtain high performance, and conduct our
analysis to uncover application and file system designs that
violate the contract. Our analysis, which utilizes a highly
detailed SSD simulation underneath traces taken from real
workloads and file systems, provides insight into how to better construct applications, file systems, and FTLs to realize
robust and sustainable performance.
