We have traditionally setup our mysql database servers with a mix of ssd and spinning disk drives.
We use the ssd drives (Raid-1) for the mysql tablespace data, and we use the spinning disks (15 sas in Raid-1) for the index data, etc.
I am wondering if going forward we should simply put all of the data on the ssd drives. Does anyone have any information on whether or not we would see any significant performance increase if we made this switch?
I have been thinking about using 4 ssd drives (Raid-10) going forward…and wondering if we should expect to see any improvement in the database performance.
Thanks in advance,
