HDD Transfer rate question

I have a 500GB WD5000AAVS external drive that I took out of the case and made internal. I benchmarked it as a secondary drive and got a 78.1MB/s transfer rate. I then benchmarked my 250GB WD2500JS drive and got 58.4MB/s transfer rate. My question is, why is the 250GB drive significantly slower than the 500GB drive? Both are SATA2 drives. I have tried swapping cables and using a different SATA port. I have also heard of my drive reaching speeds of up to 80MB/s.

SATA2 has a theoretical transfer speed of 300MB/s. Why put that if nothing will ever reach that speed? (Correct me if I am wrong on that statement)
 
SSD can beat that speed already. which is why they have sata-3 coming.

SAS has been 6GB already.

keep in mind you do not have to plug in just one device to a port. expanders do exist!

As you stated, it's a "theoretical" speed.
It's common knowledge that "theoretical" speeds aren't achieved in real world application.

Guess what...
SATA 6 (as they want it to be known), WON'T have real world application speeds of 6Gb/s. :roll:
