Intel 330 SSD speed Sequential: 350MB/Read and 280MB/Write?

I have the Inel 330 SSD with the latest firmware

I ran tests on a SuperMicro Motherboard SATA2 and got speeds of 250MB/s READ and then

installed a HighPoint Pcie2.0 card which is SATA3 and got 350MB/Read, is the fastest it will go?

I like that there was an improvement, but I just thought it would be faster.

I believe I have all the googled' settings properly set, and the latest drivers.

I am running system 32bit windows 8

4GB Ram (2.99 GB Usable)

Motherboard model is: http://www.supermicro.com/products/motherboard/Xeon3000/946/PDSBM-LN2_.cfm Super Micro Computer, Inc. - Products | Motherboards | Pentium® D Boards | PDSBM-LN2+

Rocket 640L is: Marvell 88SE9235 // PCI-Express 2.0 x4

The Rocket is running in the Universal Slot 1 (x4) (x8 physical) PCI-Express Slot via a riser card

[ ] compress this drive to save disk space is not checked

i set page swap size to ZERO

Write Cache is enabled

Anything I am missing to get faster speeds?

I haven't seen the 400MB/s-500MB/s with Sata3 drives ever?

I want to see that happen.

I got a response back from SuperMicro Support (Motherboard maker)

and they said it was:

"It is PCi-e 1.0"

So the reason I am getting the 350-390MB/s sequential read speeds in

because it's using 2 lanes?

There is no difference in speed between PCIe 1.0 and 1.1. Why SuperMicro said it is PCIe 1.0 I don't know, but it doesn't matter.

Yes, the use of two lanes each for input and output add up to 5Gb/s, the same as the older single PCIe lane Marvell SATA chips, when used on a PCIe 2.0 board.
