SSD Showing No Performance Increase Over SAS? (no replies)

I'm testing SSDs for use with MySql and am unable to see any performance benefits. This makes me feel like I must be doing something wrong.

Here is the setup:

* Xeon 5520 2.26 Ghz Quad Core
* 12 GB Ram
* 300GB 15k in RAID 1
* 64GB SSD in RAID 1

For the test I moved the mysql directory on the SSD.

I imported a table with 3 million rows. Then imported the same table with the data and index directories symlinked to the 15k drive.

Loading the data into the tables via a dump from mysqldump the 15k drives showed a faster insert rate over the SSDs:

* 15k ~= 35,800 inserts/sec
* SSD != 27,000 inserts/sec

Then I tested SELECT speed by doing 'SELECT * FROM table INTO OUTFILE '/tmp/table.txt':

* 15kk ~= 3,000,000 rows in 4.19 seconds
* SSD ~= 3,000,000 rows in 4.21 seconds

The SELECTS were almost identical and the writes were actually slower on the SSD which does not seem right at all. Any thoughts on what I should look into next?

Note: I tuned the SSD with the standard changes: noatime and noob-scheduler with no change.
