This session is about SSD deployment strategies for MySQL. For example, is it fine to store all files on SSD or is it faster to store some files (i.e. binary log files) on HDD? Is RAID 5 SSD fast enough? Do traditional H/W raid cards perform well for many(4-8) SSDs? Do MyISAM/InnoDB/other engines work well for SSD? I'll talk about these topics based on many kinds of recent benchmarking results.
