A nice article, with backing paper surveying a lot of interesting high-performance characteristics of hard drives, SATA SSDs, NVMe SSDs, and Optane devices.

Reading from External Memory

There are really a lot of different io_uring crates for rust. Some are quick bindings, some are specialized to particular application or runtime environments, some are doing deeper experiments to how they connect to the applications using the interface, I think I'll start looking at them to contrast their approaches in a little more detail.

A paper on use of per-file Erasure Coding redundancy in the EOS Filesystem used at CERN. Reasonably basic use of EC at this level of description, but it is always nice to see a review of various design decisons in a real world system.

Abstract, comments and links further on.
