Hi, I consider buying one of these Intel SSDs for my Database (MLC).
I have a few questions regarding this, maybe some of you already have some experience with that.
- which files should not be put onto the SSD (pg_clog ? pg_xlog ? ) to reduce wear (which may be an issue with the MLC variant)
- is there really a significant performance gain for random reads on a 30GB Database ?
-are there guides for tuning pg on SSD available ? (I guess some of the Planner Cost Constants should be quite differend on an SSD to achive optimal performance, as random_page_cost and seq_page_cost may be quite identical )
currently I have a lot of small random reads/writes causing heavy iowait.
