I want to test two different Disks, one of them is HDD and another is SSD
I use exactly same information and app for both servers. They are exactly same, just one of them is SSD and another is HARD.
When I run simple script that insert 1000000 rows in database, They take similar time to run (Some times HARD is faster !)
I want to know does MySQL's MyISAM use any caching, so I can get same time to insert or I have same disk.
If they use cache before insert , how can I disable that to test disk speed .
