FlashFire: Buffer-Based Write Reordering For SSDs

FlashFire is a buffer-based write reordering layer for SSDs on Linux, which can lead to greater disk performance for flash-based storage devices.

The FlashFire description according to the Google Code project site is "In many flash storage devices, write performance can be surprisingly enhanced by changing the order of requests in a proper way. However, the current OS storage software stacks are not fully exploiting this opportunity. In this project, we propose and design FlashFire, a low level per-device buffering layer having a dedicated purpose of write request reordering in Linux."

While this is an interesting write reordering layer for Linux, the GPLv2-licensed code hasn't been touched in nearly two years.
