New Relic is the largest SAAS based Application Performance Monitoring provider. We have 9 MYSQL shards that collectively handle million data points per second. Our original disk subsystem was 15k HDD drives in a RAID-5 configuration. As our site load grew, the disk subsystem was starting to behave less predictably and was becoming a bottleneck. After several months of research and testing we decided to make the plunge to SSD.

This talk will chronicle our experience moving from HDDs to SSDs and will include:

1) Architectural descriptions of before/after

2) Technical considerations with SSDs

3) Testing methodologies & benchmark results

4) MYSQL tuning for high I/O environments, with benchmark results

5) MYSQL tuning specific to SSDs, with benchmark results

6) Real-world disk utilization data before/after the cut-over
