There’s never enough time to read everything that’s worth reading, so even though Guy Harrison’s blog is one of the ones worth reading I find that it’s often months since I last read it. Visiting it late last night, I found an interesting batch of articles spread over the last year about the performance of SSD – the conclusions may not be what you expect, but make sure you read all the articles or you might end up with a completely misleading impression:
- Using flash disk for redo on Exadata
- Using SSD for redo on Exadata – pt. 2
- Exadata smart flash logging
- Exadata smart flash logging – outliers
Don’t forget to read the comments as well. For other notes Guy has written about SSD, here’s a URL for his SSD tag.
