In this paper, we are the first to characterize the trade-off of performance and index size in existing SSD-based graph and cluster indexes: to improve throughput by 5. 7$\times$ and 1. 7$\times$, these indexes have to pay a 5. 8$\times$ storage amplification and 7. 7$\times$ with respect to the dataset size, respectively.
