Samsung 840 EVO Performance Degradation

Hello folks,
I have a concern regarding my recent SSD purchase. I bought the Samsung 840 EVO (250GB), after reading great reviews from this website, and many others. The performance, however, doesn't come anywhere close to the bench marked numbers on Tom's Hardware, or the claimed IOPS. It says the maximum IOPS is supposed to be 97000. I am, however, getting 22000 random 4K reads QD32, and around the same number for the random 4K writes QD32.

I do have my Samsung Drive Magician software set up, and I have the latest firmware. I think I have SATA II on my laptop, although I know having SATA II shouldn't really matter all that much in terms of IOPS.

I am very confused to why I can't get the claimed performace out of the drive, and the numers that the Tom's Hardware team was able to achieve. Does anybody know what's wrong with my SSD?

On a side note, this is my first SSD and I love it. Because I haven't had an SSD before though, I am worried that I possibly have gotten a faulty slow unit that needs replacement. Please Help! Thanks!

SATA 3 would make Random IOPS faster...? I thought it would be more of a sequential IOPS improvement...

I have the ASUS K52JT. I believe that it only supports SATA 3Gb/s. At this SATA configuration though, what numbers am I supposed to be seeing? The drive claims way higher speeds...
