Hi Gurus
Asus Rampage extreme 3 motherboard and a Samsung 840 Pro 256 gb (brand new)
I plugged the SSD into the 6 GB/S port. I went into the bios and set the Marvel 6gb/s port to AHCI.
I run AS SSD and get the following
read write
Seq 376 229
4K 30 59
4K-64thrd 218 126
Acc time .073 .051
Score 286 209
647
This seems slow when I compare to the posts that get over 500
I installed the latest Marvel drivers and no change. Am I doing something wrong or is the speed fine
Thanks guys

Your benchmark results are normal.

X58 Chipset based motherboards do not have native 6Gb/s ports. Your motherboard uses a Marvell controller for the 6Gb/s ports. That controller was released in 2009 and can't handle the speeds of current generation SSDs.

You need a motherboard with Intel 6Gb/s ports in order to get advertised Read/Write speeds from current generation SSDs.
