Solid State Drives

Solid State Drives (SSDs) are rapidly becoming widely deployed in laptops and even data centres. They have some interesting differences from rotating media, which anyone who has an interest in Linux storage will want to understand. Getting the best performance out of SSDs requires some tweaking of the Linux kernel. Some of the changes were quite straight-forward while others required some extensive meandering through bits of the kernel that would initially seem quite unrelated. This presentation describes all the work I've been doing on this over the past year and includes performance measurements.
