SSD Speed Test on MBP 13" Kingston HyperX 120GB

Whats up guys/gals?

First of all i just picked up my first MBP 13" from the Apple store on 9/11/13

In those few days ive done a few things.

First i removed the HDD and installed my Kingston HyperX 120GB SSD that was previously in my desktop.

I also removed the optical drive, Installed the stock 500GB drive in a Data Doubler.

Its boothing quite fast and its nice to have all this extra storage, however,

on "Disk Speed Test" im only showing 140MB/s write & 410MB/s read.

I have not done anything with system settings after installing this drive. Do i need to enable TRIM? Is it ok to sleep the MBP (close the lid) on the SSD?

The speeds seem a bit slow for a SSD. Is there anything i am missing?

Here are some photos.
