Improving I/O efficiency and resilience

[Nelson H. F. Beebe]

Today's new issue of ACM Transactions on Storage contains a long
article on SSD performance that may be of interest to HAMMER
architects:

	Performance Modeling and Practical Use Cases for Black-Box {SSDs}
	ToS 17(2) 14:1--14:38 June 2021
	https://doi.org/10.1145/3440022

The same issue contains another article on filesystem resilience:

	Can Applications Recover from fsync Failures?
	ToS 17(2) 12:1--12:30 June 2021
	https://doi.org/10.1145/3450338

At least for Linux's EXT4, XFS, and BTRFS, the answer to the
title question is no.
